The example below parses args and options from `process.argv`, leaving remaining args as the `program.args` array which were not consumed by options. - -```js -#!/usr/bin/env node - -/** - * Module dependencies. - */ - -var program = require('commander'); - -program - .version('0.1.0') - .option('-p, --peppers', 'Add peppers') - .option('-P, --pineapple', 'Add pineapple') - .option('-b, --bbq-sauce', 'Add bbq sauce') - .option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble') - .parse(process.argv); - -console.log('you ordered a pizza with:'); -if (program.peppers) console.log(' - peppers'); -if (program.pineapple) console.log(' - pineapple'); -if (program.bbqSauce) console.log(' - bbq'); -console.log(' - %s cheese', program.cheese); -``` - -Short flags may be passed as a single arg, for example `-abc` is equivalent to `-a -b -c`. Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc. - -Note that multi-word options starting with `--no` prefix negate the boolean value of the following word. For example, `--no-sauce` sets the value of `program.sauce` to false. - -```js -#!/usr/bin/env node - -/** - * Module dependencies. - */ - -var program = require('commander'); - -program - .option('--no-sauce', 'Remove sauce') - .parse(process.argv); - -console.log('you ordered a pizza'); -if (program.sauce) console.log(' with sauce'); -else console.log(' without sauce'); -``` - -To get string arguments from options you will need to use angle brackets <> for required inputs or square brackets [] for optional inputs. - -e.g. ```.option('-m --myarg [myVar]', 'my super cool description')``` - -Then to access the input if it was passed in. - -e.g. ```var myInput = program.myarg``` - -**NOTE**: If you pass a argument without using brackets the example above will return true and not the value passed in. - - -## Version option - -Calling the `version` implicitly adds the `-V` and `--version` options to the command. -When either of these options is present, the command prints the version number and exits. - - $ ./examples/pizza -V - 0.0.1 - -If you want your program to respond to the `-v` option instead of the `-V` option, simply pass custom flags to the `version` method using the same syntax as the `option` method. - -```js -program - .version('0.0.1', '-v, --version') -``` - -The version flags can be named anything, but the long option is required. - -## Command-specific options - -You can attach options to a command. - -```js -#!/usr/bin/env node - -var program = require('commander'); - -program - .command('rm ') - .option('-r, --recursive', 'Remove recursively') - .action(function (dir, cmd) { - console.log('remove ' + dir + (cmd.recursive ?

However, if an action-based command does not define an action, then the options are not validated. - -## Coercion - -```js -function range(val) { - return val.split('..').map(Number); -} - -function list(val) { - return val.split(','); -} - -function collect(val, memo) { - memo.push(val); - return memo; -} - -function increaseVerbosity(v, total) { - return total + 1; -} - -program - .version('0.1.0') - .usage('[options] ') - .option('-i, --integer ', 'An integer argument', parseInt) - .option('-f, --float ', 'A float argument', parseFloat) - .option('-r, --range ..', 'A range', range) - .option('-l, --list ', 'A list', list) - .option('-o, --optional [value]', 'An optional value') - .option('-c, --collect [value]', 'A repeatable value', collect, []) - .option('-v, --verbose', 'A value that can be increased', increaseVerbosity, 0) - .parse(process.argv); - -console.log(' int: %j', program.integer); -console.log(' float: %j', program.float); -console.log(' optional: %j', program.optional); -program.range = program.range || []; -console.log(' range: %j..%j', program.range[0], program.range[1]); -console.log(' list: %j', program.list); -console.log(' collect: %j', program.collect); -console.log(' verbosity: %j', program.verbose); -console.log(' args: %j', program.args); -``` - -## Regular Expression -```js -program - .version('0.1.0') - .option('-s --size ', 'Pizza size', /^(large|medium|small)$/i, 'medium') - .option('-d --drink [drink]', 'Drink', /^(coke|pepsi|izze)$/i) - .parse(process.argv); - -console.log(' size: %j', program.size); -console.log(' drink: %j', program.drink); -``` - -## Variadic arguments - - The last argument of a command can be variadic, and only the last argument. To make an argument variadic you have to - append `...` to the argument name. Here is an example: - -```js -#!/usr/bin/env node - -/** - * Module dependencies. - */ - -var program = require('commander'); - -program - .version('0.1.0') - .command('rmdir [otherDirs...]') - .action(function (dir, otherDirs) { - console.log('rmdir %s', dir); - if (otherDirs) { - otherDirs.forEach(function (oDir) { - console.log('rmdir %s', oDir); - }); - } - }); - -program.parse(process.argv); -``` - - An `Array` is used for the value of a variadic argument. This applies to `program.args` as well as the argument passed - to your action as demonstrated above. - -## Specify the argument syntax - -```js -#!/usr/bin/env node - -var program = require('commander'); - -program - .version('0.1.0') - .arguments(' [env]') - .action(function (cmd, env) { - cmdValue = cmd; - envValue = env; - }); - -program.parse(process.argv); - -if (typeof cmdValue === 'undefined') { - console.error('no command given!'); - process.exit(1); -} -console.log('command:', cmdValue); -console.log('environment:', envValue || "no environment given"); -``` -Angled brackets (e.g. ``) indicate required input. Square brackets (e.g. `[env]`) indicate optional input. - -## Git-style sub-commands - -```js -// file: ./examples/pm -var program = require('commander'); - -program - .version('0.1.0') - .command('install [name]', 'install one or more packages') - .command('search [query]', 'search with optional query') - .command('list', 'list packages installed', {isDefault: true}) - .parse(process.argv); -``` - -When `.command()` is invoked with a description argument, no `.action(callback)` should be called to handle sub-commands, otherwise there will be an error. This tells commander that you're going to use separate executables for sub-commands, much like `git(1)` and other popular tools. -The commander will try to search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-command`, like `pm-install`, `pm-search`. - -Options can be passed with the call to `.command()`. Specifying `true` for `opts.noHelp` will remove the subcommand from the generated help output. Specifying `true` for `opts.isDefault` will run the subcommand if no other subcommand is specified. - -If the program is designed to be installed globally, make sure the executables have proper modes, like `755`. - -### `--harmony` - -You can enable `--harmony` option in two ways: -* Use `#! /usr/bin/env node --harmony` in the sub-commands scripts. Note some os version don’t support this pattern. -* Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning sub-command process. - -## Automated --help - - The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free: - -``` -$ ./examples/pizza --help -Usage: pizza [options] - -An application for pizzas ordering - -Options: - -h, --help output usage information - -V, --version output the version number - -p, --peppers Add peppers - -P, --pineapple Add pineapple - -b, --bbq Add bbq sauce - -c, --cheese Add the specified type of cheese [marble] - -C, --no-cheese You do not want any cheese -``` - -## Custom help - - You can display arbitrary `-h, --help` information - by listening for "--help". Commander will automatically - exit once you are done so that the remainder of your program - does not execute causing undesired behaviors, for example - in the following executable "stuff" will not output when - `--help` is used. - -```js -#!/usr/bin/env node - -/** - * Module dependencies. - */ - -var program = require('commander'); - -program - .version('0.1.0') - .option('-f, --foo', 'enable some foo') - .option('-b, --bar', 'enable some bar') - .option('-B, --baz', 'enable some baz'); - -// must be before .parse() since -// node's emit() is immediate - -program.on('--help', function(){ - console.log('') - console.log('Examples:'); - console.log(' $ custom-help --help'); - console.log(' $ custom-help -h'); -}); - -program.parse(process.argv); - -console.log('stuff'); -``` - -Yields the following help output when `node script-name.js -h` or `node script-name.js --help` are run: - -``` -Usage: custom-help [options] - -Options: - -h, --help output usage information - -V, --version output the version number - -f, --foo enable some foo - -b, --bar enable some bar - -B, --baz enable some baz - -Examples: - $ custom-help --help - $ custom-help -h -``` - -## .outputHelp(cb) - -Output help information without exiting. -Optional callback cb allows post-processing of help text before it is displayed. - -If you want to display help by default (e.g. if no command was provided), you can use something like: - -```js -var program = require('commander'); -var colors = require('colors'); - -program - .version('0.1.0') - .command('getstream [url]', 'get stream URL') - .parse(process.argv); - -if (!process.argv.slice(2).length) { - program.outputHelp(make_red); -} - -function make_red(txt) { - return colors.red(txt); //display the help text in red on the console -} -``` - -## .help(cb) - - Output help information and exit immediately. - Optional callback cb allows post-processing of help text before it is displayed. - - -## Custom event listeners - You can execute custom actions by listening to command and option events. - -```js -program.on('option:verbose', function () { - process.env.VERBOSE = this.verbose; -}); - -// error on unknown commands -program.on('command:*', function () { - console.error('Invalid command: %s\nSee --help for a list of available commands.', program.args.join(' ')); - process.exit(1);

For example, the median can be computed using *p* = 0.5, the first quartile at *p* = 0.25, and the third quartile at *p* = 0.75. This particular implementation uses the [R-7 method](http://en.wikipedia.org/wiki/Quantile#Quantiles_of_a_population), which is the default for the R programming language and Excel. For example: - -```js -var a = [0, 10, 30]; -d3.quantile(a, 0); // 0 -d3.quantile(a, 0.5); // 10 -d3.quantile(a, 1); // 30 -d3.quantile(a, 0.25); // 5 -d3.quantile(a, 0.75); // 20 -d3.quantile(a, 0.1); // 2 -``` - -An optional *accessor* function may be specified, which is equivalent to calling *array*.map(*accessor*) before computing the quantile. - -# d3.variance(array[, accessor]) [<>](https://github.com/d3/d3-array/blob/master/src/variance.js "Source") - -Returns an [unbiased estimator of the population variance](http://mathworld.wolfram.com/SampleVariance.html) of the given *array* of numbers.

If the given *array* contains no comparable elements (*i.e.*, the comparator returns NaN when comparing each element to itself), returns undefined. If *comparator* is not specified, it defaults to [ascending](#ascending). For example: - -```js -var array = [{foo: 42}, {foo: 91}]; -d3.scan(array, function(a, b) { return a.foo - b.foo; }); // 0 -d3.scan(array, function(a, b) { return b.foo - a.foo; }); // 1 -``` - -This function is similar to [min](#min), except it allows the use of a comparator rather than an accessor and it returns the index instead of the accessed value. See also [bisect](#bisect). - -# d3.bisectLeft(array, x[, lo[, hi]]) [<>](https://github.com/d3/d3-array/blob/master/src/bisect.js#L6 "Source") - -Returns the insertion point for *x* in *array* to maintain sorted order. The arguments *lo* and *hi* may be used to specify a subset of the array which should be considered; by default the entire array is used. If *x* is already present in *array*, the insertion point will be before (to the left of) any existing entries. The return value is suitable for use as the first argument to [splice](https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/splice) assuming that *array* is already sorted. The returned insertion point *i* partitions the *array* into two halves so that all *v* < *x* for *v* in *array*.slice(*lo*, *i*) for the left side and all *v* >= *x* for *v* in *array*.slice(*i*, *hi*) for the right side. - -# d3.bisect(array, x[, lo[, hi]]) [<>](https://github.com/d3/d3-array/blob/master/src/bisect.js "Source")
-# d3.bisectRight(array, x[, lo[, hi]]) [<>](https://github.com/d3/d3-array/blob/master/src/bisect.js#L6 "Source") - -Similar to [bisectLeft](#bisectLeft), but returns an insertion point which comes after (to the right of) any existing entries of *x* in *array*. The returned insertion point *i* partitions the *array* into two halves so that all *v* <= *x* for *v* in *array*.slice(*lo*, *i*) for the left side and all *v* > *x* for *v* in *array*.slice(*i*, *hi*) for the right side. - -# d3.bisector(accessor) [<>](https://github.com/d3/d3-array/blob/master/src/bisector.js "Source") -
# d3.bisector(comparator) [<>](https://github.com/d3/d3-array/blob/master/src/bisector.js "Source") - -Returns a new bisector using the specified *accessor* or *comparator* function. This method can be used to bisect arrays of objects instead of being limited to simple arrays of primitives. For example, given the following array of objects: - -```js -var data = [ - {date: new Date(2011, 1, 1), value: 0.5}, - {date: new Date(2011, 2, 1), value: 0.6}, - {date: new Date(2011, 3, 1), value: 0.7}, - {date: new Date(2011, 4, 1), value: 0.8} -]; -``` - -A suitable bisect function could be constructed as: - -```js -var bisectDate = d3.bisector(function(d) { return d.date; }).right; -``` - -This is equivalent to specifying a comparator: - -```js -var bisectDate = d3.bisector(function(d, x) { return d.date - x; }).right; -``` - -And then applied as *bisectDate*(*array*, *date*), returning an index. Note that the comparator is always passed the search value *x* as the second argument. Use a comparator rather than an accessor if you want values to be sorted in an order different than natural order, such as in descending rather than ascending order. - -# bisector.left(array, x[, lo[, hi]]) [<>](https://github.com/d3/d3-array/blob/master/src/bisector.js#L6 "Source") - -Equivalent to [bisectLeft](#bisectLeft), but uses this bisector’s associated comparator. - -# bisector.right(array, x[, lo[, hi]]) [<>](https://github.com/d3/d3-array/blob/master/src/bisector.js#L16 "Source") - -Equivalent to [bisectRight](#bisectRight), but uses this bisector’s associated comparator. - -# d3.ascending(a, b) [<>](https://github.com/d3/d3-array/blob/master/src/ascending.js "Source") - -Returns -1 if *a* is less than *b*, or 1 if *a* is greater than *b*, or 0. This is the comparator function for natural order, and can be used in conjunction with the built-in [*array*.sort](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort) method to arrange elements in ascending order. It is implemented as: - -```js -function ascending(a, b) { - return a < b ? -1 : a > b ? 1 : a >= b ? 0 : NaN; -} -``` - -Note that if no comparator function is specified to the built-in sort method, the default order is lexicographic (alphabetical), not natural! This can lead to surprising behavior when sorting an array of numbers. - -# d3.descending(a, b) [<>](https://github.com/d3/d3-array/blob/master/src/descending.js "Source") - -Returns -1 if *a* is greater than *b*, or 1 if *a* is less than *b*, or 0. This is the comparator function for reverse natural order, and can be used in conjunction with the built-in array sort method to arrange elements in descending order. It is implemented as: - -```js -function descending(a, b) { - return b < a ? -1 : b > a ? 1 : b >= a ? 0 : NaN; -} -``` - -Note that if no comparator function is specified to the built-in sort method, the default order is lexicographic (alphabetical), not natural! This can lead to surprising behavior when sorting an array of numbers. - -### Transformations - -Methods for transforming arrays and for generating new arrays. - -# d3.cross(a, b[, reducer]) [<>](https://github.com/d3/d3-array/blob/master/src/cross.js "Source") - -Returns the [Cartesian product](https://en.wikipedia.org/wiki/Cartesian_product) of the two arrays *a* and *b*. For each element *i* in the specified array *a* and each element *j* in the specified array *b*, in order, invokes the specified *reducer* function passing the element *i* and element *j*. If a *reducer* is not specified, it defaults to a function which creates a two-element array for each pair: - -```js -function pair(a, b) { - return [a, b]; -} -``` - -For example: - -```js -d3.cross([1, 2], ["x", "y"]); // returns [[1, "x"], [1, "y"], [2, "x"], [2, "y"]] -d3.cross([1, 2], ["x", "y"], (a, b) => a + b); // returns ["1x", "1y", "2x", "2y"] -``` - -# d3.merge(arrays) [<>](https://github.com/d3/d3-array/blob/master/src/merge.js "Source") - -Merges the specified *arrays* into a single array. This method is similar to the built-in array concat method; the only difference is that it is more convenient when you have an array of arrays. - -```js -d3.merge([[1], [2, 3]]); // returns [1, 2, 3] -``` - -# d3.pairs(array[, reducer]) [<>](https://github.com/d3/d3-array/blob/master/src/pairs.js "Source") - -For each adjacent pair of elements in the specified *array*, in order, invokes the specified *reducer* function passing the element *i* and element *i* - 1. If a *reducer* is not specified, it defaults to a function which creates a two-element array for each pair: - -```js -function pair(a, b) { - return [a, b]; -} -``` - -For example: - -```js -d3.pairs([1, 2, 3, 4]); // returns [[1, 2], [2, 3], [3, 4]] -d3.pairs([1, 2, 3, 4], (a, b) => b - a); // returns [1, 1, 1]; -``` - -If the specified array has fewer than two elements, returns the empty array. - -# d3.permute(array, indexes) [<>](https://github.com/d3/d3-array/blob/master/src/permute.js "Source") - -Returns a permutation of the specified *array* using the specified array of *indexes*. The returned array contains the corresponding element in array for each index in indexes, in order. For example, permute(["a", "b", "c"], [1, 2, 0]) -returns ["b", "c", "a"]. It is acceptable for the array of indexes to be a different length from the array of elements, and for indexes to be duplicated or omitted. - -This method can also be used to extract the values from an object into an array with a stable order. Extracting keyed values in order can be useful for generating data arrays in nested selections. For example: - -```js -var object = {yield: 27, variety: "Manchuria", year: 1931, site: "University Farm"}, - fields = ["site", "variety", "yield"]; - -d3.permute(object, fields); // returns ["University Farm", "Manchuria", 27] -``` - -# d3.shuffle(array[, start[, stop]]) [<>](https://github.com/d3/d3-array/blob/master/src/shuffle.js "Source") - -Randomizes the order of the specified *array* in-place using the [Fisher–Yates shuffle](https://bost.ocks.org/mike/shuffle/) and returns the *array*. If *start* is specified, it is the starting index (inclusive) of the *array* to shuffle; if *start* is not specified, it defaults to zero. If *stop* is specified, it is the ending index (exclusive) of the *array* to shuffle; if *stop* is not specified, it defaults to *array*.length. For example, to shuffle the first ten elements of the *array*: shuffle(*array*, 0, 10). - -# d3.ticks(start, stop, count) [<>](https://github.com/d3/d3-array/blob/master/src/ticks.js "Source") - -Returns an array of approximately *count* + 1 uniformly-spaced, nicely-rounded values between *start* and *stop* (inclusive). Each value is a power of ten multiplied by 1, 2 or 5. See also [d3.tickIncrement](#tickIncrement), [d3.tickStep](#tickStep) and [*linear*.ticks](https://github.com/d3/d3-scale/blob/master/README.md#linear_ticks). - -Ticks are inclusive in the sense that they may include the specified *start* and *stop* values if (and only if) they are exact, nicely-rounded values consistent with the inferred [step](#tickStep). More formally, each returned tick *t* satisfies *start* ≤ *t* and *t* ≤ *stop*. - -# d3.tickIncrement(start, stop, count) [<>](https://github.com/d3/d3-array/blob/master/src/ticks.js#L16 "Source") - -Like [d3.tickStep](#tickStep), except requires that *start* is always less than or equal to *step*, and if the tick step for the given *start*, *stop* and *count* would be less than one, returns the negative inverse tick step instead. This method is always guaranteed to return an integer, and is used by [d3.ticks](#ticks) to avoid guarantee that the returned tick values are represented as precisely as possible in IEEE 754 floating point. - -# d3.tickStep(start, stop, count) [<>](https://github.com/d3/d3-array/blob/master/src/ticks.js#L16 "Source") - -Returns the difference between adjacent tick values if the same arguments were passed to [d3.ticks](#ticks): a nicely-rounded value that is a power of ten multiplied by 1, 2 or 5. Note that due to the limited precision of IEEE 754 floating point, the returned value may not be exact decimals; use [d3-format](https://github.com/d3/d3-format) to format numbers for human consumption. - -# d3.range([start, ]stop[, step]) [<>](https://github.com/d3/d3-array/blob/master/src/range.js "Source") - -Returns an array containing an arithmetic progression, similar to the Python built-in [range](http://docs.python.org/library/functions.html#range). This method is often used to iterate over a sequence of uniformly-spaced numeric values, such as the indexes of an array or the ticks of a linear scale. (See also [d3.ticks](#ticks) for nicely-rounded values.) - -If *step* is omitted, it defaults to 1. If *start* is omitted, it defaults to 0. The *stop* value is exclusive; it is not included in the result. If *step* is positive, the last element is the largest *start* + *i* \* *step* less than *stop*; if *step* is negative, the last element is the smallest *start* + *i* \* *step* greater than *stop*. If the returned array would contain an infinite number of values, an empty range is returned. - -The arguments are not required to be integers; however, the results are more predictable if they are. The values in the returned array are defined as *start* + *i* \* *step*, where *i* is an integer from zero to one minus the total number of elements in the returned array. For example: - -```js -d3.range(0, 1, 0.2) // [0, 0.2, 0.4, 0.6000000000000001, 0.8] -``` - -This unexpected behavior is due to IEEE 754 double-precision floating point, which defines 0.2 * 3 = 0.6000000000000001. Use [d3-format](https://github.com/d3/d3-format) to format numbers for human consumption with appropriate rounding; see also [linear.tickFormat](https://github.com/d3/d3-scale/blob/master/README.md#linear_tickFormat) in [d3-scale](https://github.com/d3/d3-scale). - -Likewise, if the returned array should have a specific length, consider using [array.map](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map) on an integer range. For example: - -```js -d3.range(0, 1, 1 / 49); // BAD: returns 50 elements! -d3.range(49).map(function(d) { return d / 49; }); // GOOD: returns 49 elements. -``` - -# d3.transpose(matrix) [<>](https://github.com/d3/d3-array/blob/master/src/transpose.js "Source") - -Uses the [zip](#zip) operator as a two-dimensional [matrix transpose](http://en.wikipedia.org/wiki/Transpose). - -# d3.zip(arrays…) [<>](https://github.com/d3/d3-array/blob/master/src/zip.js "Source") - -Returns an array of arrays, where the *i*th array contains the *i*th element from each of the argument *arrays*. The returned array is truncated in length to the shortest array in *arrays*. If *arrays* contains only a single array, the returned array contains one-element arrays. With no arguments, the returned array is empty. - -```js -d3.zip([1, 2], [3, 4]); // returns [[1, 3], [2, 4]] -``` - -### Histograms - -[Histogram](http://bl.ocks.org/mbostock/3048450) - -Histograms bin many discrete samples into a smaller number of consecutive, non-overlapping intervals. They are often used to visualize the distribution of numerical data. - -# d3.histogram() [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js "Source") - -Constructs a new histogram generator with the default settings. - -# histogram(data) [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js#L14 "Source") - -Computes the histogram for the given array of *data* samples. Returns an array of bins, where each bin is an array containing the associated elements from the input *data*. Thus, the `length` of the bin is the number of elements in that bin. Each bin has two additional attributes: - -* `x0` - the lower bound of the bin (inclusive). -* `x1` - the upper bound of the bin (exclusive, except for the last bin). - -# histogram.value([value]) [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js#L58 "Source") - -If *value* is specified, sets the value accessor to the specified function or constant and returns this histogram generator. If *value* is not specified, returns the current value accessor, which defaults to the identity function. - -When a histogram is [generated](#_histogram), the value accessor will be invoked for each element in the input data array, being passed the element `d`, the index `i`, and the array `data` as three arguments. The default value accessor assumes that the input data are orderable (comparable), such as numbers or dates. If your data are not, then you should specify an accessor that returns the corresponding orderable value for a given datum. - -This is similar to mapping your data to values before invoking the histogram generator, but has the benefit that the input data remains associated with the returned bins, thereby making it easier to access other fields of the data. - -# histogram.domain([domain]) [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js#L62 "Source") - -If *domain* is specified, sets the domain accessor to the specified function or array and returns this histogram generator. If *domain* is not specified, returns the current domain accessor, which defaults to [extent](#extent). The histogram domain is defined as an array [*min*, *max*], where *min* is the minimum observable value and *max* is the maximum observable value; both values are inclusive. Any value outside of this domain will be ignored when the histogram is [generated](#_histogram). - -For example, if you are using the the histogram in conjunction with a [linear scale](https://github.com/d3/d3-scale/blob/master/README.md#linear-scales) `x`, you might say: - -```js -var histogram = d3.histogram() - .domain(x.domain()) - .thresholds(x.ticks(20)); -``` - -You can then compute the bins from an array of numbers like so: - -```js -var bins = histogram(numbers); -``` - -Note that the domain accessor is invoked on the materialized array of [values](#histogram_value), not on the input data array. - -# histogram.thresholds([count]) [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js#L66 "Source") -
# histogram.thresholds([thresholds]) [<>](https://github.com/d3/d3-array/blob/master/src/histogram.js#L66 "Source") - -If *thresholds* is specified, sets the [threshold generator](#histogram-thresholds) to the specified function or array and returns this histogram generator. If *thresholds* is not specified, returns the current threshold generator, which by default implements [Sturges’ formula](#thresholdSturges). (Thus by default, the histogram values must be numbers!) Thresholds are defined as an array of values [*x0*, *x1*, …]. Any value less than *x0* will be placed in the first bin; any value greater than or equal to *x0* but less than *x1* will be placed in the second bin; and so on. Thus, the [generated histogram](#_histogram) will have *thresholds*.length + 1 bins. See [histogram thresholds](#histogram-thresholds) for more information. - -Any threshold values outside the [domain](#histogram_domain) are ignored. The first *bin*.x0 is always equal to the minimum domain value, and the last *bin*.x1 is always equal to the maximum domain value. - -If a *count* is specified instead of an array of *thresholds*, then the [domain](#histogram_domain) will be uniformly divided into approximately *count* bins; see [ticks](#ticks). - -### Histogram Thresholds - -These functions are typically not used directly; instead, pass them to [*histogram*.thresholds](#histogram_thresholds). You may also implement your own threshold generator taking three arguments: the array of input [*values*](#histogram_value) derived from the data, and the [observable domain](#histogram_domain) represented as *min* and *max*. The generator may then return either the array of numeric thresholds or the *count* of bins; in the latter case the domain is divided uniformly into approximately *count* bins; see [ticks](#ticks). - -# d3.thresholdFreedmanDiaconis(values, min, max) [<>](https://github.com/d3/d3-array/blob/master/src/threshold/freedmanDiaconis.js "Source") - -Returns the number of bins according to the [Freedman–Diaconis rule](https://en.wikipedia.org/wiki/Histogram#Mathematical_definition); the input *values* must be numbers. - -# d3.thresholdScott(values, min, max) [<>](https://github.com/d3/d3-array/blob/master/src/threshold/scott.js "Source") - -Returns the number of bins according to [Scott’s normal reference rule](https://en.wikipedia.org/wiki/Histogram#Mathematical_definition); the input *values* must be numbers. - -# d3.thresholdSturges(values) [<>](https://github.com/d3/d3-array/blob/master/src/threshold/sturges.js "Source") - -Returns the number of bins according to [Sturges’ formula](https://en.wikipedia.org/wiki/Histogram#Mathematical_definition); the input *values* must be numbers. diff --git a/node_modules/d3-array/dist/d3-array.js b/node_modules/d3-array/dist/d3-array.js deleted file mode 100644 index 89d17e73a07fda9a2c52e72e8b8d43d311c87d03..0000000000000000000000000000000000000000 --- a/node_modules/d3-array/dist/d3-array.js +++ /dev/null @@ -1,590 +0,0 @@ -// https://d3js.org/d3-array/ v1.2.4 Copyright 2018 Mike Bostock -(function (global, factory) { -typeof exports === 'object' && typeof module !== 'undefined' ? factory(exports) : -typeof define === 'function' && define.amd ? define(['exports'], factory) : -(factory((global.d3 = global.d3 || {}))); -}(this, (function (exports) { 'use strict'; - -function ascending(a, b) { - return a < b ? -1 : a > b ? 1 : a >= b ? 0 : NaN; -} - -function bisector(compare) { - if (compare.length === 1) compare = ascendingComparator(compare); - return { - left: function(a, x, lo, hi) { - if (lo == null) lo = 0; - if (hi == null) hi = a.length; - while (lo < hi) { - var mid = lo + hi >>> 1; - if (compare(a[mid], x) < 0) lo = mid + 1; - else hi = mid; - } - return lo; - }, - right: function(a, x, lo, hi) { - if (lo == null) lo = 0; - if (hi == null) hi = a.length; - while (lo < hi) { - var mid = lo + hi >>> 1; - if (compare(a[mid], x) > 0) hi = mid; - else lo = mid + 1; - } - return lo; - } - }; -} - -function ascendingComparator(f) { - return function(d, x) { - return ascending(f(d), x); - }; -} - -var ascendingBisect = bisector(ascending); -var bisectRight = ascendingBisect.right; -var bisectLeft = ascendingBisect.left; - -function pairs(array, f) { - if (f == null) f = pair; - var i = 0, n = array.length - 1, p = array[0], pairs = new Array(n < 0 ? 0 : n); - while (i < n) pairs[i] = f(p, p = array[++i]); - return pairs; -} - -function pair(a, b) { - return [a, b]; -} - -function cross(values0, values1, reduce) { - var n0 = values0.length, - n1 = values1.length, - values = new Array(n0 * n1), - i0, - i1, - i, - value0; - - if (reduce == null) reduce = pair; - - for (i0 = i = 0; i0 < n0; ++i0) { - for (value0 = values0[i0], i1 = 0; i1 < n1; ++i1, ++i) { - values[i] = reduce(value0, values1[i1]); - } - } - - return values; -} - -function descending(a, b) { - return b < a ? -1 : b > a ? 1 : b >= a ? 0 : NaN; -} - -function number(x) { - return x === null ?

This alleviates one of the more tedious tasks in visualizing data. - -## Installing - -If you use NPM, `npm install d3-axis`. Otherwise, download the [latest release](https://github.com/d3/d3-axis/releases/latest). You can also load directly from [d3js.org](https://d3js.org), either as a [standalone library](https://d3js.org/d3-axis.v1.min.js) or as part of [D3 4.0](https://github.com/d3/d3). (To be useful, you’ll also want to use [d3-scale](https://github.com/d3/d3-scale) and [d3-selection](https://github.com/d3/d3-selection), but these are soft dependencies.) AMD, CommonJS, and vanilla environments are supported. In vanilla, a `d3` global is exported: - -```html - - -``` - -[Try d3-axis in your browser.](https://tonicdev.com/npm/d3-axis) - -## API Reference - -Regardless of orientation, axes are always rendered at the origin. To change the position of the axis with respect to the chart, specify a [transform attribute](http://www.w3.org/TR/SVG/coords.html#TransformAttribute) on the containing element. For example: - -```js -d3.select("body").append("svg") - .attr("width", 1440) - .attr("height", 30) - .append("g") - .attr("transform", "translate(0,30)") - .call(axis); -``` - -The elements created by the axis are considered part of its public API. You can apply external stylesheets or modify the generated axis elements to [customize the axis appearance](https://bl.ocks.org/mbostock/3371592). - -[Custom Axis](http://bl.ocks.org/mbostock/3371592) - -An axis consists of a [path element](https://www.w3.org/TR/SVG/paths.html#PathElement) of class “domain” representing the extent of the scale’s domain, followed by transformed [g elements](https://www.w3.org/TR/SVG/struct.html#Groups) of class “tick” representing each of the scale’s ticks. Each tick has a [line element](https://www.w3.org/TR/SVG/shapes.html#LineElement) to draw the tick line, and a [text element](https://www.w3.org/TR/SVG/text.html#TextElement) for the tick label.

A null format indicates that the scale’s default formatter should be used, which is generated by calling [*scale*.tickFormat](https://github.com/d3/d3-scale/blob/master/README.md#continuous_tickFormat).

If *size* is not specified, returns the current outer tick size, which defaults to 6. The outer tick size controls the length of the square ends of the domain path, offset from the native position of the axis. Thus, the “outer ticks” are not actually ticks but part of the domain path, and their position is determined by the associated scale’s domain extent. Thus, outer ticks may overlap with the first or last inner tick. An outer tick size of 0 suppresses the square ends of the domain path, instead producing a straight line. - -# axis.tickPadding([padding]) [<>](https://github.com/d3/d3-axis/blob/master/src/axis.js#L152 "Source") - -If *padding* is specified, sets the padding to the specified value in pixels and returns the axis.

Brushing is often used to select discrete elements, such as dots in a scatterplot or files on a desktop. It can also be used to zoom-in to a region of interest, or to select continuous regions for [cross-filtering data](http://square.github.io/crossfilter/) or live histograms: - -[Mona Lisa Histogram](http://bl.ocks.org/mbostock/0d20834e3d5a46138752f86b9b79727e) - -The d3-brush module implements brushing for mouse and touch events using [SVG](https://www.w3.org/TR/SVG/). Click and drag on the brush selection to translate the selection. Click and drag on one of the selection handles to move the corresponding edge (or edges) of the selection. Click and drag on the invisible overlay to define a new brush selection, or click anywhere within the brushable region while holding down the META (⌘) key. Holding down the ALT (⌥) key while moving the brush causes it to reposition around its center, while holding down SPACE locks the current brush size, allowing only translation. - -Brushes also support programmatic control. For example, you can listen to [*end* events](#brush-events), and then initiate a transition with [*brush*.move](#brush_move) to snap the brush selection to semantic boundaries: - -[Brush Snapping](http://bl.ocks.org/mbostock/6232537) - -Or you can have the brush recenter when you click outside the current selection: - -[Click-to-Recenter](https://bl.ocks.org/mbostock/6498000) - -## Installing - -If you use NPM, `npm install d3-brush`. Otherwise, download the [latest release](https://github.com/d3/d3-brush/releases/latest). You can load as a [standalone library](https://d3js.org/d3-brush.v1.min.js) or as part of [D3](https://github.com/d3/d3). ES modules, AMD, CommonJS, and vanilla environments are supported.

This function is typically not invoked directly, and is instead invoked via [*selection*.call](https://github.com/d3/d3-selection#selection_call). For example, to render a brush: - -```js -svg.append("g") - .attr("class", "brush") - .call(d3.brush().on("brush", brushed)); -``` - -Internally, the brush uses [*selection*.on](https://github.com/d3/d3-selection#selection_on) to bind the necessary event listeners for dragging. The listeners use the name `.brush`, so you can subsequently unbind the brush event listeners as follows: - -```js -group.on(".brush", null); -``` - -The brush also creates the SVG elements necessary to display the brush selection and to receive input events for interaction. You can add, remove or modify these elements as desired to change the brush appearance; you can also apply stylesheets to modify the brush appearance. The structure of a two-dimensional brush is as follows: - -```html - - - - - - - - - - - - -``` - -The overlay rect covers the brushable area defined by [*brush*.extent](#brush_extent). The selection rect covers the area defined by the current [brush selection](#brushSelection). The handle rects cover the edges and corners of the brush selection, allowing the corresponding value in the brush selection to be modified interactively. To modify the brush selection programmatically, use [*brush*.move](#brush_move). - -# brush.move(group, selection) [<>](https://github.com/d3/d3-brush/blob/master/src/brush.js "Source") - -Sets the active *selection* of the brush on the specified *group*, which must be a [selection](https://github.com/d3/d3-selection) or a [transition](https://github.com/d3/d3-transition) of SVG [G elements](https://www.w3.org/TR/SVG/struct.html#Groups). The *selection* must be defined as an array of numbers, or null to clear the brush selection. For a [two-dimensional brush](#brush), it must be defined as [[*x0*, *y0*], [*x1*, *y1*]], where *x0* is the minimum *x*-value, *y0* is the minimum *y*-value, *x1* is the maximum *x*-value, and *y1* is the maximum *y*-value. For an [*x*-brush](#brushX), it must be defined as [*x0*, *x1*]; for a [*y*-brush](#brushY), it must be defined as [*y0*, *y1*]. The selection may also be specified as a function which returns such an array; if a function, it is invoked for each selected element, being passed the current datum `d` and index `i`, with the `this` context as the current DOM element. The returned array defines the brush selection for that element. - -# brush.clear(group) [<>](https://github.com/d3/d3-brush/blob/master/src/brush.js "Source") - -An alias for [*brush*.move](#brush_move) with the null selection. - -# brush.extent([extent]) [<>](https://github.com/d3/d3-brush/blob/master/src/brush.js "Source") - -If *extent* is specified, sets the brushable extent to the specified array of points [[*x0*, *y0*], [*x1*, *y1*]], where [*x0*, *y0*] is the top-left corner and [*x1*, *y1*] is the bottom-right corner, and returns this brush. The *extent* may also be specified as a function which returns such an array; if a function, it is invoked for each selected element, being passed the current datum `d` and index `i`, with the `this` context as the current DOM element. If *extent* is not specified, returns the current extent accessor, which defaults to: - -```js -function defaultExtent() { - var svg = this.ownerSVGElement || this; - if (svg.hasAttribute("viewBox")) { - svg = svg.viewBox.baseVal; - return [[svg.x, svg.y], [svg.x + svg.width, svg.y + svg.height]]; - } - return [[0, 0], [svg.width.baseVal.value, svg.height.baseVal.value]]; -} -``` - -This default implementation requires that the owner SVG element have a defined [viewBox](https://www.w3.org/TR/SVG/coords.html#ViewBoxAttribute), or [width](https://www.w3.org/TR/SVG/struct.html#SVGElementWidthAttribute) and [height](https://www.w3.org/TR/SVG/struct.html#SVGElementHeightAttribute) attributes. Alternatively, consider using [*element*.getBoundingClientRect](https://developer.mozilla.org/en-US/docs/Web/API/Element/getBoundingClientRect). (In Firefox, [*element*.clientWidth](https://developer.mozilla.org/en-US/docs/Web/API/Element/clientWidth) and [*element*.clientHeight](https://developer.mozilla.org/en-US/docs/Web/API/Element/clientHeight) is zero for SVG elements!) - -The brush extent determines the size of the invisible overlay and also constrains the brush selection; the brush selection cannot go outside the brush extent. - -# brush.filter([filter]) [<>](https://github.com/d3/d3-brush/blob/master/src/brush.js "Source") - -If *filter* is specified, sets the filter to the specified function and returns the brush.

Thus, the filter determines which input events are ignored. The default filter ignores mousedown events on secondary buttons, since those buttons are typically intended for other purposes, such as the context menu. - -# brush.touchable([touchable]) [<>](https://github.com/d3/d3-brush/blob/master/src/brush.js "Source") - -If *touchable* is specified, sets the touch support detector to the specified function and returns the brush. If *touchable* is not specified, returns the current touch support detector, which defaults to: - -```js -function touchable() { - return navigator.maxTouchPoints || ("ontouchstart" in this); -} -``` - -Touch event listeners are only registered if the detector returns truthy for the corresponding element when the brush is [applied](#_brush). The default detector works well for most browsers that are capable of touch input, but not all; Chrome’s mobile device emulator, for example, fails detection. - -# brush.keyModifiers([modifiers]) [<>](https://github.com/d3/d3-brush/blob/master/src/brush.js "Source") - -If *modifiers* is specified, sets whether the brush listens to key events during brushing and returns the brush.

If *size* is not specified, returns the current handle size, which defaults to six. This method must be called before [applying the brush](#_brush) to a selection; changing the handle size does not affect brushes that were previously rendered. - -# brush.on(typenames[, listener]) [<>](https://github.com/d3/d3-brush/blob/master/src/brush.js "Source") - -If *listener* is specified, sets the event *listener* for the specified *typenames* and returns the brush. If an event listener was already registered for the same type and name, the existing listener is removed before the new listener is added. If *listener* is null, removes the current event listeners for the specified *typenames*, if any. If *listener* is not specified, returns the first currently-assigned listener matching the specified *typenames*, if any. When a specified event is dispatched, each *listener* will be invoked with the same context and arguments as [*selection*.on](https://github.com/d3/d3-selection#selection_on) listeners: the current datum `d` and index `i`, with the `this` context as the current DOM element. - -The *typenames* is a string containing one or more *typename* separated by whitespace. Each *typename* is a *type*, optionally followed by a period (`.`) and a *name*, such as `brush.foo` and `brush.bar`; the name allows multiple listeners to be registered for the same *type*. The *type* must be one of the following: - -* `start` - at the start of a brush gesture, such as on mousedown. -* `brush` - when the brush moves, such as on mousemove. -* `end` - at the end of a brush gesture, such as on mouseup. - -See [*dispatch*.on](https://github.com/d3/d3-dispatch#dispatch_on) and [Brush Events](#brush-events) for more. - -# d3.brushSelection(node) [<>](https://github.com/d3/d3-brush/blob/master/src/brush.js "Source") - -Returns the current brush selection for the specified *node*. Internally, an element’s brush state is stored as *element*.\_\_brush; however, you should use this method rather than accessing it directly. If the given *node* has no selection, returns null. Otherwise, the *selection* is defined as an array of numbers. For a [two-dimensional brush](#brush), it is [[*x0*, *y0*], [*x1*, *y1*]], where *x0* is the minimum *x*-value, *y0* is the minimum *y*-value, *x1* is the maximum *x*-value, and *y1* is the maximum *y*-value. For an [*x*-brush](#brushX), it is [*x0*, *x1*]; for a [*y*-brush](#brushY), it is [*y0*, *y1*]. - -### Brush Events - -When a [brush event listener](#brush_on) is invoked, [d3.event](https://github.com/d3/d3-selection#event) is set to the current brush event. The *event* object exposes several fields: - -* `target` - the associated [brush behavior](#brush). -* `type` - the string “start”, “brush” or “end”; see [*brush*.on](#brush_on). -* `selection` - the current [brush selection](#brushSelection). -* `sourceEvent` - the underlying input event, such as mousemove or touchmove. diff --git a/node_modules/d3-brush/dist/d3-brush.js b/node_modules/d3-brush/dist/d3-brush.js deleted file mode 100644 index 186166d1a5c1948de9c3ca1a43f98f37c1b7008f..0000000000000000000000000000000000000000 --- a/node_modules/d3-brush/dist/d3-brush.js +++ /dev/null @@ -1,617 +0,0 @@ -// https://d3js.org/d3-brush/ v1.1.5 Copyright 2019 Mike Bostock -(function (global, factory) { -typeof exports === 'object' && typeof module !== 'undefined' ?

The given *matrix* must be an array of length *n*, where each element *matrix*[*i*] is an array of *n* numbers, where each *matrix*[*i*][*j*] represents the flow from the *i*th node in the network to the *j*th node. Each number *matrix*[*i*][*j*] must be nonnegative, though it can be zero if there is no flow from node *i* to node *j*.

In other words, *chord*.source.index equals *chord*.target.subindex, *chord*.source.subindex equals *chord*.target.index, *chord*.source.value is greater than or equal to *chord*.target.value, and *chord*.source.value is always greater than zero. - -The *chords* array also defines a secondary array of length *n*, *chords*.groups, where each group represents the combined outflow for node *i*, corresponding to the elements *matrix*[*i*][0 … *n* - 1], and is an object with the following properties: - -* `startAngle` - the start angle in radians -* `endAngle` - the end angle in radians -* `value` - the total outgoing flow value for node *i* -* `index` - the node index *i* - -The groups are typically passed to [d3.arc](https://github.com/d3/d3-shape#arc) to produce a donut chart around the circumference of the chord layout. - -# chord.padAngle([angle]) [<>](https://github.com/d3/d3-chord/blob/master/src/chord.js#L104 "Source") - -If *angle* is specified, sets the pad angle between adjacent groups to the specified number in radians and returns this chord layout.

The standard mechanism for iterating over the keys (or property names) in an associative array is the [for…in loop](https://developer.mozilla.org/en/JavaScript/Reference/Statements/for...in). However, note that the iteration order is undefined. D3 provides several methods for converting associative arrays to standard arrays with numeric indexes. - -A word of caution: it is tempting to use plain objects as maps, but this causes [unexpected behavior](http://www.devthought.com/2012/01/18/an-object-is-not-a-hash/) when built-in property names are used as keys, such as `object["__proto__"] = 42` and `"hasOwnProperty" in object`. If you cannot guarantee that map keys and set values will be safe, use [maps](#maps) and [sets](#sets) (or their ES6 equivalents) instead of plain objects. - -# d3.keys(object) [<>](https://github.com/d3/d3-collection/blob/master/src/keys.js "Source") - -Returns an array containing the property names of the specified object (an associative array). The order of the returned array is undefined. - -# d3.values(object) [<>](https://github.com/d3/d3-collection/blob/master/src/values.js "Source") - -Returns an array containing the property values of the specified object (an associative array). The order of the returned array is undefined. - -# d3.entries(object) [<>](https://github.com/d3/d3-collection/blob/master/src/entries.js "Source") - -Returns an array containing the property keys and values of the specified object (an associative array). Each entry is an object with a key and value attribute, such as `{key: "foo", value: 42}`. The order of the returned array is undefined. - -```js -d3.entries({foo: 42, bar: true}); // [{key: "foo", value: 42}, {key: "bar", value: true}] -``` - -### Maps - -Like [ES6 Maps](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map), but with a few differences: - -* Keys are coerced to strings. -* [map.each](#map_each), not [map.forEach](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map/forEach). (Also, no *thisArg*.) -* [map.remove](#map_remove), not [map.delete](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map/delete). -* [map.entries](#map_entries) returns an array of {key, value} objects, not an iterator of [key, value]. -* [map.size](#map_size) is a method, not a [property](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map/size); also, there’s [map.empty](#map_empty). - -# d3.map([object[, key]]) [<>](https://github.com/d3/d3-collection/blob/master/src/map.js "Source") - -Constructs a new map. If *object* is specified, copies all enumerable properties from the specified object into this map. The specified object may also be an array or another map. An optional *key* function may be specified to compute the key for each value in the array. For example: - -```js -var map = d3.map([{name: "foo"}, {name: "bar"}], function(d) { return d.name; }); -map.get("foo"); // {"name": "foo"} -map.get("bar"); // {"name": "bar"} -map.get("baz"); // undefined -``` - -See also [nests](#nests). - -# map.has(key) [<>](https://github.com/d3/d3-collection/blob/master/src/map.js#L7 "Source") - -Returns true if and only if this map has an entry for the specified *key* string. Note: the value may be `null` or `undefined`. - -# map.get(key) [<>](https://github.com/d3/d3-collection/blob/master/src/map.js#L10 "Source") - -Returns the value for the specified *key* string. If the map does not have an entry for the specified *key*, returns `undefined`. - -# map.set(key, value) [<>](https://github.com/d3/d3-collection/blob/master/src/map.js#L13 "Source") - -Sets the *value* for the specified *key* string. If the map previously had an entry for the same *key* string, the old entry is replaced with the new value. Returns the map, allowing chaining. For example: - -```js -var map = d3.map() - .set("foo", 1) - .set("bar", 2) - .set("baz", 3); - -map.get("foo"); // 1 -``` - -# map.remove(key) [<>](https://github.com/d3/d3-collection/blob/master/src/map.js#L17 "Source") - -If the map has an entry for the specified *key* string, removes the entry and returns true. Otherwise, this method does nothing and returns false. - -# map.clear() [<>](https://github.com/d3/d3-collection/blob/master/src/map.js#L21 "Source") - -Removes all entries from this map. - -# map.keys() [<>](https://github.com/d3/d3-collection/blob/master/src/map.js#L24 "Source") - -Returns an array of string keys for every entry in this map. The order of the returned keys is arbitrary. - -# map.values() [<>](https://github.com/d3/d3-collection/blob/master/src/map.js#L29 "Source") - -Returns an array of values for every entry in this map. The order of the returned values is arbitrary. - -# map.entries() [<>](https://github.com/d3/d3-collection/blob/master/src/map.js#L34 "Source") - -Returns an array of key-value objects for each entry in this map. The order of the returned entries is arbitrary. Each entry’s key is a string, but the value has arbitrary type. - -# map.each(function) [<>](https://github.com/d3/d3-collection/blob/master/src/map.js#L48 "Source") - -Calls the specified *function* for each entry in this map, passing the entry’s value and key as arguments, followed by the map itself. Returns undefined. The iteration order is arbitrary. - -# map.empty() [<>](https://github.com/d3/d3-collection/blob/master/src/map.js#L44 "Source") - -Returns true if and only if this map has zero entries. - -# map.size() [<>](https://github.com/d3/d3-collection/blob/master/src/map.js#L39 "Source") - -Returns the number of entries in this map. - -### Sets - -Like [ES6 Sets](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set), but with a few differences: - -* Values are coerced to strings. -* [set.each](#set_each), not [set.forEach](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set/forEach). (Also, no *thisArg*.) -* [set.remove](#set_remove), not [set.delete](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set/delete). -* [set.size](#set_size) is a method, not a [property](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set/size); also, there’s [set.empty](#set_empty). - -# d3.set([array[, accessor]]) [<>](https://github.com/d3/d3-collection/blob/master/src/set.js "Source") - -Constructs a new set. If *array* is specified, adds the given *array* of string values to the returned set. The specified array may also be another set. An optional *accessor* function may be specified, which is equivalent to calling *array.map(accessor)* before constructing the set. - -# set.has(value) [<>](https://github.com/d3/d3-collection/blob/master/src/set.js#L9 "Source") - -Returns true if and only if this set has an entry for the specified *value* string. - -# set.add(value) [<>](https://github.com/d3/d3-collection/blob/master/src/set.js#L10 "Source") - -Adds the specified *value* string to this set. Returns the set, allowing chaining. For example: - -```js -var set = d3.set() - .add("foo") - .add("bar") - .add("baz"); - -set.has("foo"); // true -``` - -# set.remove(value) [<>](https://github.com/d3/d3-collection/blob/master/src/set.js#L15 "Source") - -If the set contains the specified *value* string, removes it and returns true. Otherwise, this method does nothing and returns false. - -# set.clear() [<>](https://github.com/d3/d3-collection/blob/master/src/set.js#L16 "Source") - -Removes all values from this set. - -# set.values() [<>](https://github.com/d3/d3-collection/blob/master/src/set.js#L17 "Source") - -Returns an array of the string values in this set. The order of the returned values is arbitrary. Can be used as a convenient way of computing the unique values for a set of strings. For example: - -```js -d3.set(["foo", "bar", "foo", "baz"]).values(); // "foo", "bar", "baz" -``` - -# set.each(function) [<>](https://github.com/d3/d3-collection/blob/master/src/set.js#L20 "Source") - -Calls the specified *function* for each value in this set, passing the value as the first two arguments (for symmetry with [*map*.each](#map_each)), followed by the set itself. Returns undefined. The iteration order is arbitrary. - -# set.empty() [<>](https://github.com/d3/d3-collection/blob/master/src/set.js#L19 "Source") - -Returns true if and only if this set has zero values. - -# set.size() [<>](https://github.com/d3/d3-collection/blob/master/src/set.js#L18 "Source") - -Returns the number of values in this set. - -### Nests - -Nesting allows elements in an array to be grouped into a hierarchical tree structure; think of it like the GROUP BY operator in SQL, except you can have multiple levels of grouping, and the resulting output is a tree rather than a flat table. The levels in the tree are specified by key functions. The leaf nodes of the tree can be sorted by value, while the internal nodes can be sorted by key. An optional rollup function will collapse the elements in each leaf node using a summary function. The nest operator (the object returned by [nest](#nest)) is reusable, and does not retain any references to the data that is nested. - -For example, consider the following tabular data structure of Barley yields, from various sites in Minnesota during 1931-2: - -```js -var yields = [ - {yield: 27.00, variety: "Manchuria", year: 1931, site: "University Farm"}, - {yield: 48.87, variety: "Manchuria", year: 1931, site: "Waseca"}, - {yield: 27.43, variety: "Manchuria", year: 1931, site: "Morris"}, - ... -]; -``` - -To facilitate visualization, it may be useful to nest the elements first by year, and then by variety, as follows: - -```js -var entries = d3.nest() - .key(function(d) { return d.year; }) - .key(function(d) { return d.variety; }) - .entries(yields); -``` - -This returns a nested array. Each element of the outer array is a key-values pair, listing the values for each distinct key: - -```js -[{key: "1931", values: [ - {key: "Manchuria", values: [ - {yield: 27.00, variety: "Manchuria", year: 1931, site: "University Farm"}, - {yield: 48.87, variety: "Manchuria", year: 1931, site: "Waseca"}, - {yield: 27.43, variety: "Manchuria", year: 1931, site: "Morris"}, ...]}, - {key: "Glabron", values: [ - {yield: 43.07, variety: "Glabron", year: 1931, site: "University Farm"}, - {yield: 55.20, variety: "Glabron", year: 1931, site: "Waseca"}, ...]}, ...]}, - {key: "1932", values: ...}] -``` - -The nested form allows easy iteration and generation of hierarchical structures in SVG or HTML. - -For a longer introduction to nesting, see: - -* Phoebe Bright’s [D3 Nest Tutorial and examples](http://bl.ocks.org/phoebebright/raw/3176159/) -* Shan Carter’s [Mister Nester](http://bl.ocks.org/shancarter/raw/4748131/) - -# d3.nest() [<>](https://github.com/d3/d3-collection/blob/master/src/nest.js "Source") - -Creates a new nest operator. The set of keys is initially empty. - -# nest.key(key) [<>](https://github.com/d3/d3-collection/blob/master/src/nest.js#L4 "Source") - -Registers a new *key* function. The *key* function will be invoked for each element in the input array and must return a string identifier to assign the element to its group. Most often, the function is a simple accessor, such as the year and variety accessors above. (Keys functions are *not* passed the input array index.) Each time a key is registered, it is pushed onto the end of the internal array of keys, and the nest operator applies an additional level of nesting. - -# nest.sortKeys(comparator) [<>](https://github.com/d3/d3-collection/blob/master/src/nest.js#L5 "Source") - -Sorts key values for the [current key](#nest_key) using the specified *comparator* function, such as [d3.ascending](https://github.com/d3/d3-array#ascending) or [d3.descending](https://github.com/d3/d3-array#descending). If no comparator is specified for the current key, the order in which keys will be returned is undefined. For example, to sort years in ascending order and varieties in descending order: - -```js -var entries = d3.nest() - .key(function(d) { return d.year; }).sortKeys(d3.ascending) - .key(function(d) { return d.variety; }).sortKeys(d3.descending) - .entries(yields); -``` - -Note that this only affects the result of [*nest*.entries](#nest_entries); the order of keys returned by [*nest*.map](#nest_map) and [*nest*.object](#nest_object) is always undefined, regardless of comparator. - -# nest.sortValues(comparator) [<>](https://github.com/d3/d3-collection/blob/master/src/nest.js#L6 "Source") - -Sorts leaf elements using the specified *comparator* function, such as [d3.ascending](https://github.com/d3/d3-array#ascending) or [d3.descending](https://github.com/d3/d3-array#descending). This is roughly equivalent to sorting the input array before applying the nest operator; however it is typically more efficient as the size of each group is smaller. If no value comparator is specified, elements will be returned in the order they appeared in the input array. This applies to [*nest*.map](#nest_map), [*nest*.entries](#nest_entries) and [*nest*.object](#nest_object). - -# nest.rollup(function) [<>](https://github.com/d3/d3-collection/blob/master/src/nest.js#L7 "Source") - -Specifies a rollup *function* to be applied on each group of leaf elements. The return value of the rollup function will replace the array of leaf values in either the associative array returned by [*nest*.map](#nest_map) or [*nest*.object](#nest_object); for [*nest*.entries](#nest_entries), it replaces the leaf *entry*.values with *entry*.value. If a [leaf comparator](#nest_sortValues) is specified, the leaf elements are sorted prior to invoking the rollup function. - -# nest.map(array) [<>](https://github.com/d3/d3-collection/blob/master/src/nest.js#L50 "Source") - -Applies the nest operator to the specified *array*, returning a nested [map](#map). Each entry in the returned map corresponds to a distinct key value returned by the first key function. The entry value depends on the number of registered key functions: if there is an additional key, the value is another map; otherwise, the value is the array of elements filtered from the input *array* that have the given key value. If no keys are defined, returns the input *array*. - -# nest.object(array) [<>](https://github.com/d3/d3-collection/blob/master/src/nest.js#L49 "Source") - -Applies the nest operator to the specified *array*, returning a nested object. Each entry in the returned associative array corresponds to a distinct key value returned by the first key function. The entry value depends on the number of registered key functions: if there is an additional key, the value is another associative array; otherwise, the value is the array of elements filtered from the input *array* that have the given key value. - -Note: this method is unsafe if any of the keys conflict with built-in JavaScript properties, such as `__proto__`. If you cannot guarantee that the keys will be safe, you should use [nest.map](#nest_map) instead. - -# nest.entries(array) [<>](https://github.com/d3/d3-collection/blob/master/src/nest.js#L51 "Source") - -Applies the nest operator to the specified *array*, returning an array of key-values entries. Conceptually, this is similar to applying [*map*.entries](#map_entries) to the associative array returned by [*nest*.map](#nest_map), but it applies to every level of the hierarchy rather than just the first (outermost) level. Each entry in the returned array corresponds to a distinct key value returned by the first key function. The entry value depends on the number of registered key functions: if there is an additional key, the value is another nested array of entries; otherwise, the value is the array of elements filtered from the input *array* that have the given key value. diff --git a/node_modules/d3-collection/dist/d3-collection.js b/node_modules/d3-collection/dist/d3-collection.js deleted file mode 100644 index c70af52bc8801013e85ac1437c95bf3f4d730436..0000000000000000000000000000000000000000 --- a/node_modules/d3-collection/dist/d3-collection.js +++ /dev/null @@ -1,217 +0,0 @@ -// https://d3js.org/d3-collection/ v1.0.7 Copyright 2018 Mike Bostock -(function (global, factory) { -typeof exports === 'object' && typeof module !== 'undefined' ? factory(exports) : -typeof define === 'function' && define.amd ? define(['exports'], factory) : -(factory((global.d3 = global.d3 || {})));

The first value *x0* should typically be greater than zero. - -If a *count* is specified instead of an array of *thresholds*, then approximately *count* uniformly-spaced nicely-rounded thresholds will be generated; see [d3.ticks](https://github.com/d3/d3-array/blob/master/README.md#ticks). - -# density.bandwidth([bandwidth]) [<>](https://github.com/d3/d3-contour/blob/master/src/density.js "Source") - -If *bandwidth* is specified, sets the bandwidth (the standard deviation) of the Gaussian kernel and returns the estimate. If *bandwidth* is not specified, returns the current bandwidth, which defaults to 20.4939…. The specified *bandwidth* is currently rounded to the nearest supported value by this implementation, and must be nonnegative. diff --git a/node_modules/d3-contour/dist/d3-contour.js b/node_modules/d3-contour/dist/d3-contour.js deleted file mode 100644 index 9bbd766b5abf19ec3e75e9988821def57c9ea394..0000000000000000000000000000000000000000 --- a/node_modules/d3-contour/dist/d3-contour.js +++ /dev/null @@ -1,431 +0,0 @@ -// https://d3js.org/d3-contour/ v1.3.2 Copyright 2018 Mike Bostock -(function (global, factory) { -typeof exports === 'object' && typeof module !== 'undefined' ? factory(exports, require('d3-array')) : -typeof define === 'function' && define.amd ? define(['exports', 'd3-array'], factory) : -(factory((global.d3 = global.d3 || {}),global.d3));

The subject is then exposed as *event*.subject on subsequent [drag events](#drag-events) for this gesture. - -The default subject is the [datum](https://github.com/d3/d3-selection#selection_datum) of the element in the originating selection (see [*drag*](#_drag)) that received the initiating input event; if this datum is undefined, an object representing the coordinates of the pointer is created. When dragging circle elements in SVG, the default subject is thus the datum of the circle being dragged. With [Canvas](https://html.spec.whatwg.org/multipage/scripting.html#the-canvas-element), the default subject is the canvas element’s datum (regardless of where on the canvas you click). In this case, a custom subject accessor would be more appropriate, such as one that picks the closest circle to the mouse within a given search *radius*: - -```js -function subject() { - var n = circles.length, - i, - dx, - dy, - d2, - s2 = radius * radius, - circle, - subject; - - for (i = 0; i < n; ++i) { - circle = circles[i]; - dx = d3.event.x - circle.x; - dy = d3.event.y - circle.y; - d2 = dx * dx + dy * dy; - if (d2 < s2) subject = circle, s2 = d2; - } - - return subject; -} -``` - -(If necessary, the above can be accelerated using [*quadtree*.find](https://github.com/d3/d3-quadtree#quadtree_find).) - -The returned subject should be an object that exposes `x` and `y` properties, so that the relative position of the subject and the pointer can be preserved during the drag gesture. If the subject is null or undefined, no drag gesture is started for this pointer; however, other starting touches may yet start drag gestures. See also [*drag*.filter](#drag_filter). - -The subject of a drag gesture may not be changed after the gesture starts. The subject accessor is invoked with the same context and arguments as [*selection*.on](https://github.com/d3/d3-selection#selection_on) listeners: the current datum `d` and index `i`, with the `this` context as the current DOM element. During the evaluation of the subject accessor, [d3.event](https://github.com/d3/d3-selection#event) is a beforestart [drag event](#drag-events). Use *event*.sourceEvent to access the initiating input event and *event*.identifier to access the touch identifier. The *event*.x and *event*.y are relative to the [container](#drag_container), and are computed using [d3.mouse](https://github.com/d3/d3-selection#mouse) or [d3.touch](https://github.com/d3/d3-selection#touch) as appropriate. - -# drag.clickDistance([distance]) [<>](https://github.com/d3/d3-drag/blob/master/src/drag.js#L162 "Source") - -If *distance* is specified, sets the maximum distance that the mouse can move between mousedown and mouseup that will trigger a subsequent click event. If at any point between mousedown and mouseup the mouse is greater than or equal to *distance* from its position on mousedown, the click event following mouseup will be suppressed. If *distance* is not specified, returns the current distance threshold, which defaults to zero. The distance threshold is measured in client coordinates ([*event*.clientX](https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/clientX) and [*event*.clientY](https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/clientY)). - -# drag.on(typenames, [listener]) [<>](https://github.com/d3/d3-drag/blob/master/src/drag.js#L157 "Source") - -If *listener* is specified, sets the event *listener* for the specified *typenames* and returns the drag behavior. If an event listener was already registered for the same type and name, the existing listener is removed before the new listener is added. If *listener* is null, removes the current event listeners for the specified *typenames*, if any. If *listener* is not specified, returns the first currently-assigned listener matching the specified *typenames*, if any. When a specified event is dispatched, each *listener* will be invoked with the same context and arguments as [*selection*.on](https://github.com/d3/d3-selection#selection_on) listeners: the current datum `d` and index `i`, with the `this` context as the current DOM element. - -The *typenames* is a string containing one or more *typename* separated by whitespace. Each *typename* is a *type*, optionally followed by a period (`.`) and a *name*, such as `drag.foo` and `drag.bar`; the name allows multiple listeners to be registered for the same *type*. The *type* must be one of the following: - -* `start` - after a new pointer becomes active (on mousedown or touchstart). -* `drag` - after an active pointer moves (on mousemove or touchmove). -* `end` - after an active pointer becomes inactive (on mouseup, touchend or touchcancel). - -See [*dispatch*.on](https://github.com/d3/d3-dispatch#dispatch_on) for more. - -Changes to registered listeners via *drag*.on during a drag gesture *do not affect* the current drag gesture. Instead, you must use [*event*.on](#event_on), which also allows you to register temporary event listeners for the current drag gesture. **Separate events are dispatched for each active pointer** during a drag gesture. For example, if simultaneously dragging multiple subjects with multiple fingers, a start event is dispatched for each finger, even if both fingers start touching simultaneously. See [Drag Events](#drag-events) for more. - -# d3.dragDisable(window) [<>](https://github.com/d3/d3-drag/blob/master/src/nodrag.js#L4 "Source") - -Prevents native drag-and-drop and text selection on the specified *window*. As an alternative to preventing the default action of mousedown events (see [#9](https://github.com/d3/d3-drag/issues/9)), this method prevents undesirable default actions following mousedown. In supported browsers, this means capturing dragstart and selectstart events, preventing the associated default actions, and immediately stopping their propagation. In browsers that do not support selection events, the user-select CSS property is set to none on the document element. This method is intended to be called on mousedown, followed by [d3.dragEnable](#dragEnable) on mouseup. - -# d3.dragEnable(window[, noclick]) [<>](https://github.com/d3/d3-drag/blob/master/src/nodrag.js#L15 "Source") - -Allows native drag-and-drop and text selection on the specified *window*; undoes the effect of [d3.dragDisable](#dragDisable). This method is intended to be called on mouseup, preceded by [d3.dragDisable](#dragDisable) on mousedown. If *noclick* is true, this method also temporarily suppresses click events. The suppression of click events expires after a zero-millisecond timeout, such that it only suppress the click event that would immediately follow the current mouseup event, if any. - -### Drag Events - -When a [drag event listener](#drag_on) is invoked, [d3.event](https://github.com/d3/d3-selection#event) is set to the current drag event. The *event* object exposes several fields: - -* `target` - the associated [drag behavior](#drag). -* `type` - the string “start”, “drag” or “end”; see [*drag*.on](#drag_on). -* `subject` - the drag subject, defined by [*drag*.subject](#drag_subject). -* `x` - the new *x*-coordinate of the subject; see [*drag*.container](#drag_container). -* `y` - the new *y*-coordinate of the subject; see [*drag*.container](#drag_container). -* `dx` - the change in *x*-coordinate since the previous drag event. -* `dy` - the change in *y*-coordinate since the previous drag event. -* `identifier` - the string “mouse”, or a numeric [touch identifier](https://www.w3.org/TR/touch-events/#widl-Touch-identifier). -* `active` - the number of currently active drag gestures (on start and end, not including this one). -* `sourceEvent` - the underlying input event, such as mousemove or touchmove. - -The *event*.active field is useful for detecting the first start event and the last end event in a sequence of concurrent drag gestures: it is zero when the first drag gesture starts, and zero when the last drag gesture ends. - -The *event* object also exposes the [*event*.on](#event_on) method. - -# event.on(typenames, [listener]) [<>](https://github.com/d3/d3-drag/blob/master/src/event.js "Source") - -Equivalent to [*drag*.on](#drag_on), but only applies to the current drag gesture. Before the drag gesture starts, a [copy](https://github.com/d3/d3-dispatch#dispatch_copy) of the current drag [event listeners](#drag_on) is made. This copy is bound to the current drag gesture and modified by *event*.on. This is useful for temporary listeners that only receive events for the current drag gesture. For example, this start event listener registers temporary drag and end event listeners as closures: - -```js -function started() { - var circle = d3.select(this).classed("dragging", true); - - d3.event.on("drag", dragged).on("end", ended); - - function dragged(d) { - circle.raise().attr("cx", d.x = d3.event.x).attr("cy", d.y = d3.event.y); - } - - function ended() { - circle.classed("dragging", false); - } -} -``` diff --git a/node_modules/d3-drag/dist/d3-drag.js b/node_modules/d3-drag/dist/d3-drag.js deleted file mode 100644 index 89d9ad410481b6e522a31e87be604b3653cd6ae7..0000000000000000000000000000000000000000 --- a/node_modules/d3-drag/dist/d3-drag.js +++ /dev/null @@ -1,234 +0,0 @@ -// https://d3js.org/d3-drag/ v1.2.5 Copyright 2019 Mike Bostock -(function (global, factory) { -typeof exports === 'object' && typeof module !== 'undefined' ?

This function is intended to be used as a *row* accessor function in conjunction with [*dsv*.parse](#dsv_parse) and [*dsv*.parseRows](#dsv_parseRow). For example, consider the following CSV file: - -``` -Year,Make,Model,Length -1997,Ford,E350,2.34 -2000,Mercury,Cougar,2.38 -``` - -When used with [d3.csvParse](#csvParse), - -```js -d3.csvParse(string, d3.autoType) -``` - -the resulting JavaScript array is: - -```js -[ - {"Year": 1997, "Make": "Ford", "Model": "E350", "Length": 2.34}, - {"Year": 2000, "Make": "Mercury", "Model": "Cougar", "Length": 2.38} -] -``` - -Type inference works as follows. For each *value* in the given *object*, the [trimmed](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/Trim) value is computed; the value is then re-assigned as follows: - -1. If empty, then `null`. -1. If exactly `"true"`, then `true`. -1. If exactly `"false"`, then `false`. -1. If exactly `"NaN"`, then `NaN`. -1. Otherwise, if [coercible to a number](https://www.ecma-international.org/ecma-262/9.0/index.html#sec-tonumber-applied-to-the-string-type), then a number. -1. Otherwise, if a [date-only or date-time string](https://www.ecma-international.org/ecma-262/9.0/index.html#sec-date-time-string-format), then a Date. -1. Otherwise, a string (the original untrimmed value). - -Values with leading zeroes may be coerced to numbers; for example `"08904"` coerces to `8904`. However, extra characters such as commas or units (*e.g.*, `"$1.00"`, `"(123)"`, `"1,234"` or `"32px"`) will prevent number coercion, resulting in a string. - -Date strings must be in ECMAScript’s subset of the [ISO 8601 format](https://en.wikipedia.org/wiki/ISO_8601). When a date-only string such as YYYY-MM-DD is specified, the inferred time is midnight UTC; however, if a date-time string such as YYYY-MM-DDTHH:MM is specified without a time zone, it is assumed to be local time. - -Automatic type inference is primarily intended to provide safe, predictable behavior in conjunction with [*dsv*.format](#dsv_format) and [*dsv*.formatRows](#dsv_formatRows) for common JavaScript types. If you need different behavior, you should implement your own row accessor function. - -For more, see [the d3.autoType notebook](https://observablehq.com/@d3/d3-autotype). - -### Content Security Policy - -If a [content security policy](http://www.w3.org/TR/CSP/) is in place, note that [*dsv*.parse](#dsv_parse) requires `unsafe-eval` in the `script-src` directive, due to the (safe) use of dynamic code generation for fast parsing. (See [source](https://github.com/d3/d3-dsv/blob/master/src/dsv.js).) Alternatively, use [*dsv*.parseRows](#dsv_parseRows). - -### Byte-Order Marks - -DSV files sometimes begin with a [byte order mark (BOM)](https://en.wikipedia.org/wiki/Byte_order_mark); saving a spreadsheet in CSV UTF-8 format from Microsoft Excel, for example, will include a BOM. On the web this is not usually a problem because the [UTF-8 decode algorithm](https://encoding.spec.whatwg.org/#utf-8-decode) specified in the Encoding standard removes the BOM. Node.js, on the other hand, [does not remove the BOM](https://github.com/nodejs/node-v0.x-archive/issues/1918) when decoding UTF-8. - -If the BOM is not removed, the first character of the text is a zero-width non-breaking space. So if a CSV file with a BOM is parsed by [d3.csvParse](#csvParse), the first column’s name will begin with a zero-width non-breaking space. This can be hard to spot since this character is usually invisible when printed. - -To remove the BOM before parsing, consider using [strip-bom](https://www.npmjs.com/package/strip-bom). - -## Command Line Reference - -### dsv2dsv - -# dsv2dsv [options…] [file] - -Converts the specified DSV input *file* to DSV (typically with a different delimiter or encoding).

It is most commonly used for [slow-in, slow-out](https://en.wikipedia.org/wiki/12_basic_principles_of_animation#Slow_In_and_Slow_Out). By easing time, [animated transitions](https://github.com/d3/d3-transition) are smoother and exhibit more plausible motion. - -The easing types in this module implement the [ease method](#ease_ease), which takes a normalized time *t* and returns the corresponding “eased” time *tʹ*. Both the normalized time and the eased time are typically in the range [0,1], where 0 represents the start of the animation and 1 represents the end; some easing types, such as [elastic](#easeElastic), may return eased times slightly outside this range. A good easing type should return 0 if *t* = 0 and 1 if *t* = 1. See the [easing explorer](https://observablehq.com/@d3/easing) for a visual demonstration. - -These easing types are largely based on work by [Robert Penner](http://robertpenner.com/easing/). - -## Installing - -If you use NPM, `npm install d3-ease`. Otherwise, download the [latest release](https://github.com/d3/d3-ease/releases/latest). You can also load directly from [d3js.org](https://d3js.org), either as a [standalone library](https://d3js.org/d3-ease.v1.min.js) or as part of [D3](https://github.com/d3/d3). AMD, CommonJS, and vanilla environments are supported. In vanilla, a `d3` global is exported: - -```html - - -``` - -[Try d3-ease in your browser.](https://observablehq.com/@d3/easing-animations) - -## API Reference - -# ease(t) - -Given the specified normalized time *t*, typically in the range [0,1], returns the “eased” time *tʹ*, also typically in [0,1]. 0 represents the start of the animation and 1 represents the end.

When a specified event is dispatched, each *listener* will be invoked with the `this` context as the simulation. - -The *typenames* is a string containing one or more *typename* separated by whitespace. Each *typename* is a *type*, optionally followed by a period (`.`) and a *name*, such as `tick.foo` and `tick.bar`; the name allows multiple listeners to be registered for the same *type*. The *type* must be one of the following: - -* `tick` - after each tick of the simulation’s internal timer. -* `end` - after the simulation’s timer stops when *alpha* < [*alphaMin*](#simulation_alphaMin). - -Note that *tick* events are not dispatched when [*simulation*.tick](#simulation_tick) is called manually; events are only dispatched by the internal timer and are intended for interactive rendering of the simulation.

For example, a simple positioning force that moves nodes towards the origin ⟨0,0⟩ might be implemented as: - -```js -function force(alpha) { - for (var i = 0, n = nodes.length, node, k = alpha * 0.1; i < n; ++i) { - node = nodes[i]; - node.vx -= node.x * k; - node.vy -= node.y * k; - } -} -``` - -Forces typically read the node’s current position ⟨*x*,*y*⟩ and then add to (or subtract from) the node’s velocity ⟨*vx*,*vy*⟩. However, forces may also “peek ahead” to the anticipated next position of the node, ⟨*x* + *vx*,*y* + *vy*⟩; this is necessary for resolving geometric constraints through [iterative relaxation](https://en.wikipedia.org/wiki/Relaxation_\(iterative_method\)). Forces may also modify the position directly, which is sometimes useful to avoid adding energy to the simulation, such as when recentering the simulation in the viewport. - -Simulations typically compose multiple forces as desired. This module provides several for your enjoyment: - -* [Centering](#centering) -* [Collision](#collision) -* [Links](#links) -* [Many-Body](#many-body) -* [Positioning](#positioning) - -Forces may optionally implement [*force*.initialize](#force_initialize) to receive the simulation’s array of nodes. - -# force(alpha) [<>](https://github.com/d3/d3-force/blob/master/src/simulation.js#L47 "Source") - -Applies this force, optionally observing the specified *alpha*. Typically, the force is applied to the array of nodes previously passed to [*force*.initialize](#force_initialize), however, some forces may apply to a subset of nodes, or behave differently. For example, [d3.forceLink](#links) applies to the source and target of each link. - -# force.initialize(nodes) [<>](https://github.com/d3/d3-force/blob/master/src/simulation.js#L77 "Source") - -Assigns the array of *nodes* to this force. This method is called when a force is bound to a simulation via [*simulation*.force](#simulation_force) and when the simulation’s nodes change via [*simulation*.nodes](#simulation_nodes). A force may perform necessary work during initialization, such as evaluating per-node parameters, to avoid repeatedly performing work during each application of the force. - -#### Centering - -The centering force translates nodes uniformly so that the mean position of all nodes (the center of mass if all nodes have equal weight) is at the given position ⟨[*x*](#center_x),[*y*](#center_y)⟩. This force modifies the positions of nodes on each application; it does not modify velocities, as doing so would typically cause the nodes to overshoot and oscillate around the desired center. This force helps keeps nodes in the center of the viewport, and unlike the [positioning force](#positioning), it does not distort their relative positions. - -# d3.forceCenter([x, y]) [<>](https://github.com/d3/d3-force/blob/master/src/center.js#L1 "Source") - -Creates a new centering force with the specified [*x*-](#center_x) and [*y*-](#center_y) coordinates. If *x* and *y* are not specified, they default to ⟨0,0⟩. - -# center.x([x]) [<>](https://github.com/d3/d3-force/blob/master/src/center.js#L27 "Source") - -If *x* is specified, sets the *x*-coordinate of the centering position to the specified number and returns this force. If *x* is not specified, returns the current *x*-coordinate, which defaults to zero. - -# center.y([y]) [<>](https://github.com/d3/d3-force/blob/master/src/center.js#L31 "Source") - -If *y* is specified, sets the *y*-coordinate of the centering position to the specified number and returns this force. If *y* is not specified, returns the current *y*-coordinate, which defaults to zero. - -#### Collision - -The collision force treats nodes as circles with a given [radius](#collide_radius), rather than points, and prevents nodes from overlapping. More formally, two nodes *a* and *b* are separated so that the distance between *a* and *b* is at least *radius*(*a*) + *radius*(*b*). To reduce jitter, this is by default a “soft” constraint with a configurable [strength](#collide_strength) and [iteration count](#collide_iterations). - -# d3.forceCollide([radius]) [<>](https://github.com/d3/d3-force/blob/master/src/collide.js "Source") - -Creates a new circle collision force with the specified [*radius*](#collide_radius). If *radius* is not specified, it defaults to the constant one for all nodes. - -# collide.radius([radius]) [<>](https://github.com/d3/d3-force/blob/master/src/collide.js#L86 "Source") - -If *radius* is specified, sets the radius accessor to the specified number or function, re-evaluates the radius accessor for each node, and returns this force. If *radius* is not specified, returns the current radius accessor, which defaults to: - -```js -function radius() { - return 1; -} -``` - -The radius accessor is invoked for each [node](#simulation_nodes) in the simulation, being passed the *node* and its zero-based *index*. The resulting number is then stored internally, such that the radius of each node is only recomputed when the force is initialized or when this method is called with a new *radius*, and not on every application of the force. - -# collide.strength([strength]) [<>](https://github.com/d3/d3-force/blob/master/src/collide.js#L82 "Source") - -If *strength* is specified, sets the force strength to the specified number in the range [0,1] and returns this force. If *strength* is not specified, returns the current strength which defaults to 0.7. - -Overlapping nodes are resolved through iterative relaxation. For each node, the other nodes that are anticipated to overlap at the next tick (using the anticipated positions ⟨*x* + *vx*,*y* + *vy*⟩) are determined; the node’s velocity is then modified to push the node out of each overlapping node. The change in velocity is dampened by the force’s strength such that the resolution of simultaneous overlaps can be blended together to find a stable solution. - -# collide.iterations([iterations]) [<>](https://github.com/d3/d3-force/blob/master/src/collide.js#L78 "Source") - -If *iterations* is specified, sets the number of iterations per application to the specified number and returns this force. If *iterations* is not specified, returns the current iteration count which defaults to 1. Increasing the number of iterations greatly increases the rigidity of the constraint and avoids partial overlap of nodes, but also increases the runtime cost to evaluate the force. - -#### Links - -The link force pushes linked nodes together or apart according to the desired [link distance](#link_distance). The strength of the force is proportional to the difference between the linked nodes’ distance and the target distance, similar to a spring force. - -# d3.forceLink([links]) [<>](https://github.com/d3/d3-force/blob/master/src/link.js "Source") - -Creates a new link force with the specified *links* and default parameters. If *links* is not specified, it defaults to the empty array. - -# link.links([links]) [<>](https://github.com/d3/d3-force/blob/master/src/link.js#L92 "Source") - -If *links* is specified, sets the array of links associated with this force, recomputes the [distance](#link_distance) and [strength](#link_strength) parameters for each link, and returns this force. If *links* is not specified, returns the current array of links, which defaults to the empty array. - -Each link is an object with the following properties: - -* `source` - the link’s source node; see [*simulation*.nodes](#simulation_nodes) -* `target` - the link’s target node; see [*simulation*.nodes](#simulation_nodes) -* `index` - the zero-based index into *links*, assigned by this method - -For convenience, a link’s source and target properties may be initialized using numeric or string identifiers rather than object references; see [*link*.id](#link_id). When the link force is [initialized](#force_initialize) (or re-initialized, as when the nodes or links change), any *link*.source or *link*.target property which is *not* an object is replaced by an object reference to the corresponding *node* with the given identifier. - -If the specified array of *links* is modified, such as when links are added to or removed from the simulation, this method must be called again with the new (or changed) array to notify the force of the change; the force does not make a defensive copy of the specified array. - -# link.id([id]) [<>](https://github.com/d3/d3-force/blob/master/src/link.js#L96 "Source") - -If *id* is specified, sets the node id accessor to the specified function and returns this force. If *id* is not specified, returns the current node id accessor, which defaults to the numeric *node*.index: - -```js -function id(d) { - return d.index; -} -``` - -The default id accessor allows each link’s source and target to be specified as a zero-based index into the [nodes](#simulation_nodes) array. For example: - -```js -var nodes = [ - {"id": "Alice"}, - {"id": "Bob"}, - {"id": "Carol"} -]; - -var links = [ - {"source": 0, "target": 1}, // Alice → Bob - {"source": 1, "target": 2} // Bob → Carol -]; -``` - -Now consider a different id accessor that returns a string: - -```js -function id(d) { - return d.id; -} -``` - -With this accessor, you can use named sources and targets: - -```js -var nodes = [ - {"id": "Alice"}, - {"id": "Bob"}, - {"id": "Carol"} -]; - -var links = [ - {"source": "Alice", "target": "Bob"}, - {"source": "Bob", "target": "Carol"} -]; -``` - -This is particularly useful when representing graphs in JSON, as JSON does not allow references. See [this example](http://bl.ocks.org/mbostock/f584aa36df54c451c94a9d0798caed35). - -The id accessor is invoked for each node whenever the force is initialized, as when the [nodes](#simulation_nodes) or [links](#link_links) change, being passed the node and its zero-based index. - -# link.distance([distance]) [<>](https://github.com/d3/d3-force/blob/master/src/link.js#L108 "Source") - -If *distance* is specified, sets the distance accessor to the specified number or function, re-evaluates the distance accessor for each link, and returns this force. If *distance* is not specified, returns the current distance accessor, which defaults to: - -```js -function distance() { - return 30; -} -``` - -The distance accessor is invoked for each [link](#link_links), being passed the *link* and its zero-based *index*. The resulting number is then stored internally, such that the distance of each link is only recomputed when the force is initialized or when this method is called with a new *distance*, and not on every application of the force. - -# link.strength([strength]) [<>](https://github.com/d3/d3-force/blob/master/src/link.js#L104 "Source") - -If *strength* is specified, sets the strength accessor to the specified number or function, re-evaluates the strength accessor for each link, and returns this force. If *strength* is not specified, returns the current strength accessor, which defaults to: - -```js -function strength(link) { - return 1 / Math.min(count(link.source), count(link.target)); -} -``` - -Where *count*(*node*) is a function that returns the number of links with the given node as a source or target. This default was chosen because it automatically reduces the strength of links connected to heavily-connected nodes, improving stability. - -The strength accessor is invoked for each [link](#link_links), being passed the *link* and its zero-based *index*. The resulting number is then stored internally, such that the strength of each link is only recomputed when the force is initialized or when this method is called with a new *strength*, and not on every application of the force. - -# link.iterations([iterations]) [<>](https://github.com/d3/d3-force/blob/master/src/link.js#L100 "Source") - -If *iterations* is specified, sets the number of iterations per application to the specified number and returns this force. If *iterations* is not specified, returns the current iteration count which defaults to 1. Increasing the number of iterations greatly increases the rigidity of the constraint and is useful for [complex structures such as lattices](http://bl.ocks.org/mbostock/1b64ec067fcfc51e7471d944f51f1611), but also increases the runtime cost to evaluate the force. - -#### Many-Body - -The many-body (or *n*-body) force applies mutually amongst all [nodes](#simulation_nodes). It can be used to simulate gravity (attraction) if the [strength](#manyBody_strength) is positive, or electrostatic charge (repulsion) if the strength is negative. This implementation uses quadtrees and the [Barnes–Hut approximation](https://en.wikipedia.org/wiki/Barnes–Hut_simulation) to greatly improve performance; the accuracy can be customized using the [theta](#manyBody_theta) parameter. - -Unlike links, which only affect two linked nodes, the charge force is global: every node affects every other node, even if they are on disconnected subgraphs. - -# d3.forceManyBody() [<>](https://github.com/d3/d3-force/blob/master/src/manyBody.js "Source") - -Creates a new many-body force with the default parameters. - -# manyBody.strength([strength]) [<>](https://github.com/d3/d3-force/blob/master/src/manyBody.js#L97 "Source") - -If *strength* is specified, sets the strength accessor to the specified number or function, re-evaluates the strength accessor for each node, and returns this force. A positive value causes nodes to attract each other, similar to gravity, while a negative value causes nodes to repel each other, similar to electrostatic charge. If *strength* is not specified, returns the current strength accessor, which defaults to: - -```js -function strength() { - return -30; -} -``` - -The strength accessor is invoked for each [node](#simulation_nodes) in the simulation, being passed the *node* and its zero-based *index*. The resulting number is then stored internally, such that the strength of each node is only recomputed when the force is initialized or when this method is called with a new *strength*, and not on every application of the force. - -# manyBody.theta([theta]) [<>](https://github.com/d3/d3-force/blob/master/src/manyBody.js#L109 "Source") - -If *theta* is specified, sets the Barnes–Hut approximation criterion to the specified number and returns this force. If *theta* is not specified, returns the current value, which defaults to 0.9. - -To accelerate computation, this force implements the [Barnes–Hut approximation](http://en.wikipedia.org/wiki/Barnes–Hut_simulation) which takes O(*n* log *n*) per application where *n* is the number of [nodes](#simulation_nodes). For each application, a [quadtree](https://github.com/d3/d3-quadtree) stores the current node positions; then for each node, the combined force of all other nodes on the given node is computed. For a cluster of nodes that is far away, the charge force can be approximated by treating the cluster as a single, larger node. The *theta* parameter determines the accuracy of the approximation: if the ratio *w* / *l* of the width *w* of the quadtree cell to the distance *l* from the node to the cell’s center of mass is less than *theta*, all nodes in the given cell are treated as a single node rather than individually. - -# manyBody.distanceMin([distance]) [<>](https://github.com/d3/d3-force/blob/master/src/manyBody.js#L101 "Source") - -If *distance* is specified, sets the minimum distance between nodes over which this force is considered. If *distance* is not specified, returns the current minimum distance, which defaults to 1. A minimum distance establishes an upper bound on the strength of the force between two nearby nodes, avoiding instability. In particular, it avoids an infinitely-strong force if two nodes are exactly coincident; in this case, the direction of the force is random. - -# manyBody.distanceMax([distance]) [<>](https://github.com/d3/d3-force/blob/master/src/manyBody.js#L105 "Source") - -If *distance* is specified, sets the maximum distance between nodes over which this force is considered. If *distance* is not specified, returns the current maximum distance, which defaults to infinity. Specifying a finite maximum distance improves performance and produces a more localized layout. - -#### Positioning - -The [*x*](#forceX)- and [*y*](#forceY)-positioning forces push nodes towards a desired position along the given dimension with a configurable strength. The [*radial*](#forceRadial) force is similar, except it pushes nodes towards the closest point on a given circle. The strength of the force is proportional to the one-dimensional distance between the node’s position and the target position. While these forces can be used to position individual nodes, they are intended primarily for global forces that apply to all (or most) nodes. - -# d3.forceX([x]) [<>](https://github.com/d3/d3-force/blob/master/src/x.js "Source") - -Creates a new positioning force along the *x*-axis towards the given position [*x*](#x_x). If *x* is not specified, it defaults to 0. - -# x.strength([strength]) [<>](https://github.com/d3/d3-force/blob/master/src/x.js#L32 "Source") - -If *strength* is specified, sets the strength accessor to the specified number or function, re-evaluates the strength accessor for each node, and returns this force. The *strength* determines how much to increment the node’s *x*-velocity: ([*x*](#x_x) - *node*.x) × *strength*. For example, a value of 0.1 indicates that the node should move a tenth of the way from its current *x*-position to the target *x*-position with each application. Higher values moves nodes more quickly to the target position, often at the expense of other forces or constraints. A value outside the range [0,1] is not recommended. - -If *strength* is not specified, returns the current strength accessor, which defaults to: - -```js -function strength() { - return 0.1; -} -``` - -The strength accessor is invoked for each [node](#simulation_nodes) in the simulation, being passed the *node* and its zero-based *index*.

A table of numbers should be formatted consistently for comparison; above, 0.0 would be better than 0. Large numbers should have grouped digits (e.g., 42,000) or be in scientific or metric notation (4.2e+4, 42k). Currencies should have fixed precision ($3.50). Reported numerical results should be rounded to significant digits (4021 becomes 4000). Number formats should appropriate to the reader’s locale (42.000,00 or 42,000.00). The list goes on. - -Formatting numbers for human consumption is the purpose of d3-format, which is modeled after Python 3’s [format specification mini-language](https://docs.python.org/3/library/string.html#format-specification-mini-language) ([PEP 3101](https://www.python.org/dev/peps/pep-3101/)).

Otherwise, download the [latest release](https://github.com/d3/d3-format/releases/latest). You can also load directly from [d3js.org](https://d3js.org), either as a [standalone library](https://d3js.org/d3-format.v1.min.js) or as part of [D3](https://github.com/d3/d3). AMD, CommonJS, and vanilla environments are supported. In vanilla, a `d3` global is exported: - -```html - - -``` - -Locale files are published to npm and can be loaded using [d3.json](https://github.com/d3/d3-request/blob/master/README.md#json). For example, to set Russian as the default locale: - -```js -d3.json("https://cdn.jsdelivr.net/npm/d3-format@1/locale/ru-RU.json", function(error, locale) { - if (error) throw error; - - d3.formatDefaultLocale(locale); - - var format = d3.format("$,"); - - console.log(format(1234.56)); // 1 234,56 руб. -}); -``` - -[Try d3-format in your browser.](https://observablehq.com/@d3/d3-format) - -## API Reference - -# d3.format(specifier) [<>](https://github.com/d3/d3-format/blob/master/src/defaultLocale.js#L4 "Source") - -An alias for [*locale*.format](#locale_format) on the [default locale](#formatDefaultLocale). - -# d3.formatPrefix(specifier, value) [<>](https://github.com/d3/d3-format/blob/master/src/defaultLocale.js#L5 "Source") - -An alias for [*locale*.formatPrefix](#locale_formatPrefix) on the [default locale](#formatDefaultLocale). - -# locale.format(specifier) [<>](https://github.com/d3/d3-format/blob/master/src/locale.js#L18 "Source") - -Returns a new format function for the given string *specifier*. The returned function takes a number as the only argument, and returns a string representing the formatted number. The general form of a specifier is: - -``` -[​[fill]align][sign][symbol][0][width][,][.precision][~][type] -``` - -The *fill* can be any character. The presence of a fill character is signaled by the *align* character following it, which must be one of the following: - -* `>` - Forces the field to be right-aligned within the available space. (Default behavior). -* `<` - Forces the field to be left-aligned within the available space. -* `^` - Forces the field to be centered within the available space. -* `=` - like `>`, but with any sign and symbol to the left of any padding. - -The *sign* can be: - -* `-` - nothing for zero or positive and a minus sign for negative. (Default behavior.) -* `+` - a plus sign for zero or positive and a minus sign for negative. -* `(` - nothing for zero or positive and parentheses for negative. -* ` ` (space) - a space for zero or positive and a minus sign for negative. - -The *symbol* can be: - -* `$` - apply currency symbols per the locale definition. -* `#` - for binary, octal, or hexadecimal notation, prefix by `0b`, `0o`, or `0x`, respectively. - -The *zero* (`0`) option enables zero-padding; this implicitly sets *fill* to `0` and *align* to `=`. The *width* defines the minimum field width; if not specified, then the width will be determined by the content. The *comma* (`,`) option enables the use of a group separator, such as a comma for thousands. - -Depending on the *type*, the *precision* either indicates the number of digits that follow the decimal point (types `f` and `%`), or the number of significant digits (types `​`, `e`, `g`, `r`, `s` and `p`). If the precision is not specified, it defaults to 6 for all types except `​` (none), which defaults to 12. Precision is ignored for integer formats (types `b`, `o`, `d`, `x`, `X` and `c`). See [precisionFixed](#precisionFixed) and [precisionRound](#precisionRound) for help picking an appropriate precision. - -The `~` option trims insignificant trailing zeros across all format types. This is most commonly used in conjunction with types `r`, `e`, `s` and `%`. For example: - -```js -d3.format("s")(1500); // "1.50000k" -d3.format("~s")(1500); // "1.5k" -``` - -The available *type* values are: - -* `e` - exponent notation. -* `f` - fixed point notation. -* `g` - either decimal or exponent notation, rounded to significant digits. -* `r` - decimal notation, rounded to significant digits. -* `s` - decimal notation with an [SI prefix](#locale_formatPrefix), rounded to significant digits. -* `%` - multiply by 100, and then decimal notation with a percent sign. -* `p` - multiply by 100, round to significant digits, and then decimal notation with a percent sign. -* `b` - binary notation, rounded to integer. -* `o` - octal notation, rounded to integer. -* `d` - decimal notation, rounded to integer. -* `x` - hexadecimal notation, using lower-case letters, rounded to integer. -* `X` - hexadecimal notation, using upper-case letters, rounded to integer. -* `c` - converts the integer to the corresponding unicode character before printing. - -The type `​` (none) is also supported as shorthand for `~g` (with a default precision of 12 instead of 6), and the type `n` is shorthand for `,g`. For the `g`, `n` and `​` (none) types, decimal notation is used if the resulting string would have *precision* or fewer digits; otherwise, exponent notation is used. For example: - -```js -d3.format(".2")(42); // "42" -d3.format(".2")(4.2); // "4.2" -d3.format(".1")(42); // "4e+1" -d3.format(".1")(4.2); // "4" -``` - -# locale.formatPrefix(specifier, value) [<>](https://github.com/d3/d3-format/blob/master/src/locale.js#L127 "Source") - -Equivalent to [*locale*.format](#locale_format), except the returned function will convert values to the units of the appropriate [SI prefix](https://en.wikipedia.org/wiki/Metric_prefix#List_of_SI_prefixes) for the specified numeric reference *value* before formatting in fixed point notation. The following prefixes are supported: - -* `y` - yocto, 10⁻²⁴ -* `z` - zepto, 10⁻²¹ -* `a` - atto, 10⁻¹⁸ -* `f` - femto, 10⁻¹⁵ -* `p` - pico, 10⁻¹² -* `n` - nano, 10⁻⁹ -* `µ` - micro, 10⁻⁶ -* `m` - milli, 10⁻³ -* `​` (none) - 10⁰ -* `k` - kilo, 10³ -* `M` - mega, 10⁶ -* `G` - giga, 10⁹ -* `T` - tera, 10¹² -* `P` - peta, 10¹⁵ -* `E` - exa, 10¹⁸ -* `Z` - zetta, 10²¹ -* `Y` - yotta, 10²⁴ - -Unlike [*locale*.format](#locale_format) with the `s` format type, this method returns a formatter with a consistent SI prefix, rather than computing the prefix dynamically for each number. In addition, the *precision* for the given *specifier* represents the number of digits past the decimal point (as with `f` fixed point notation), not the number of significant digits. For example: - -```js -var f = d3.formatPrefix(",.0", 1e-6); -f(0.00042); // "420µ" -f(0.0042); // "4,200µ" -``` - -This method is useful when formatting multiple numbers in the same units for easy comparison.

The *step* represents the minimum absolute difference between values that will be formatted. (This assumes that the values to be formatted are also multiples of *step*.) For example, given the numbers 1, 1.5, and 2, the *step* should be 0.5 and the suggested precision is 1: - -```js -var p = d3.precisionFixed(0.5), - f = d3.format("." + p + "f"); -f(1); // "1.0" -f(1.5); // "1.5" -f(2); // "2.0" -``` - -Whereas for the numbers 1, 2 and 3, the *step* should be 1 and the suggested precision is 0: - -```js -var p = d3.precisionFixed(1), - f = d3.format("." + p + "f"); -f(1); // "1" -f(2); // "2" -f(3); // "3" -``` - -Note: for the `%` format type, subtract two: - -```js -var p = Math.max(0, d3.precisionFixed(0.05) - 2), - f = d3.format("." + p + "%"); -f(0.45); // "45%" -f(0.50); // "50%" -f(0.55); // "55%" -``` - -# d3.precisionPrefix(step, value) [<>](https://github.com/d3/d3-format/blob/master/src/precisionPrefix.js "Source") - -Returns a suggested decimal precision for use with [*locale*.formatPrefix](#locale_formatPrefix) given the specified numeric *step* and reference *value*. The *step* represents the minimum absolute difference between values that will be formatted, and *value* determines which SI prefix will be used. (This assumes that the values to be formatted are also multiples of *step*.) For example, given the numbers 1.1e6, 1.2e6, and 1.3e6, the *step* should be 1e5, the *value* could be 1.3e6, and the suggested precision is 1: - -```js -var p = d3.precisionPrefix(1e5, 1.3e6), - f = d3.formatPrefix("." + p, 1.3e6); -f(1.1e6); // "1.1M" -f(1.2e6); // "1.2M" -f(1.3e6); // "1.3M" -``` - -# d3.precisionRound(step, max) [<>](https://github.com/d3/d3-format/blob/master/src/precisionRound.js "Source") - -Returns a suggested decimal precision for format types that round to significant digits given the specified numeric *step* and *max* values. The *step* represents the minimum absolute difference between values that will be formatted, and the *max* represents the largest absolute value that will be formatted.

For instance, spherical Mercator: - -```js -function mercator(x, y) { - return [x, Math.log(Math.tan(Math.PI / 4 + y / 2))]; -} -``` - -This is a reasonable *mathematical* approach if your geometry consists of continuous, infinite point sets. Yet computers do not have infinite memory, so we must instead work with discrete geometry such as polygons and polylines! - -Discrete geometry makes the challenge of projecting from the sphere to the plane much harder. The edges of a spherical polygon are [geodesics](https://en.wikipedia.org/wiki/Geodesic) (segments of great circles), not straight lines. Projected to the plane, geodesics are curves in all map projections except [gnomonic](#geoGnomonic), and thus accurate projection requires interpolation along each arc. D3 uses [adaptive sampling](https://bl.ocks.org/mbostock/3795544) inspired by a popular [line simplification method](https://bost.ocks.org/mike/simplify/) to balance accuracy and performance. - -The projection of polygons and polylines must also deal with the topological differences between the sphere and the plane. Some projections require cutting geometry that [crosses the antimeridian](https://bl.ocks.org/mbostock/3788999), while others require [clipping geometry to a great circle](https://bl.ocks.org/mbostock/3021474). - -Spherical polygons also require a [winding order convention](https://bl.ocks.org/mbostock/a7bdfeb041e850799a8d3dce4d8c50c8) to determine which side of the polygon is the inside: the exterior ring for polygons smaller than a hemisphere must be clockwise, while the exterior ring for polygons [larger than a hemisphere](https://bl.ocks.org/mbostock/6713736) must be anticlockwise. Interior rings representing holes must use the opposite winding order of their exterior ring. This winding order convention is also used by [TopoJSON](https://github.com/topojson) and [ESRI shapefiles](https://github.com/mbostock/shapefile); however, it is the **opposite** convention of GeoJSON’s [RFC 7946](https://tools.ietf.org/html/rfc7946#section-3.1.6). (Also note that standard GeoJSON WGS84 uses planar equirectangular coordinates, not spherical coordinates, and thus may require [stitching](https://github.com/d3/d3-geo-projection/blob/master/README.md#geostitch) to remove antimeridian cuts.) - -D3’s approach affords great expressiveness: you can choose the right projection, and the right aspect, for your data. D3 supports a wide variety of common and [unusual map projections](https://github.com/d3/d3-geo-projection). For more, see Part 2 of [The Toolmaker’s Guide](https://vimeo.com/106198518#t=20m0s). - -D3 uses [GeoJSON](http://geojson.org/geojson-spec.html) to represent geographic features in JavaScript. (See also [TopoJSON](https://github.com/mbostock/topojson), an extension of GeoJSON that is significantly more compact and encodes topology.) To convert shapefiles to GeoJSON, use [shp2geo](https://github.com/mbostock/shapefile/blob/master/README.md#shp2geo), part of the [shapefile package](https://github.com/mbostock/shapefile).

Canvas is recommended for dynamic or interactive projections to improve performance. Paths can be used with [projections](#projections) or [transforms](#transforms), or they can be used to render planar geometry directly to Canvas or SVG. - -# d3.geoPath([projection[, context]]) [<>](https://github.com/d3/d3-geo/blob/master/src/path/index.js "Source") - -Creates a new geographic path generator with the default settings.

Any additional *arguments* are passed along to the [pointRadius](#path_pointRadius) accessor. - -To display multiple features, combine them into a feature collection: - -```js -svg.append("path") - .datum({type: "FeatureCollection", features: features}) - .attr("d", d3.geoPath()); -``` - -Or use multiple path elements: - -```js -svg.selectAll("path") - .data(features) - .enter().append("path") - .attr("d", d3.geoPath()); -``` - -Separate path elements are typically slower than a single path element. However, distinct path elements are useful for styling and interaction (e.g., click or mouseover). Canvas rendering (see [*path*.context](#path_context)) is typically faster than SVG, but requires more effort to implement styling and interaction. - -# path.area(object) [<>](https://github.com/d3/d3-geo/blob/master/src/path/area.js "Source") - -Returns the projected planar area (typically in square pixels) for the specified GeoJSON *object*. Point, MultiPoint, LineString and MultiLineString geometries have zero area. For Polygon and MultiPolygon geometries, this method first computes the area of the exterior ring, and then subtracts the area of any interior holes. This method observes any clipping performed by the [projection](#path_projection); see [*projection*.clipAngle](#projection_clipAngle) and [*projection*.clipExtent](#projection_clipExtent). This is the planar equivalent of [d3.geoArea](#geoArea). - -# path.bounds(object) [<>](https://github.com/d3/d3-geo/blob/master/src/path/bounds.js "Source") - -Returns the projected planar bounding box (typically in pixels) for the specified GeoJSON *object*. The bounding box is represented by a two-dimensional array: \[\[*x₀*, *y₀*\], \[*x₁*, *y₁*\]\], where *x₀* is the minimum *x*-coordinate, *y₀* is the minimum *y*-coordinate, *x₁* is maximum *x*-coordinate, and *y₁* is the maximum *y*-coordinate. This is handy for, say, zooming in to a particular feature. (Note that in projected planar coordinates, the minimum latitude is typically the maximum *y*-value, and the maximum latitude is typically the minimum *y*-value.) This method observes any clipping performed by the [projection](#path_projection); see [*projection*.clipAngle](#projection_clipAngle) and [*projection*.clipExtent](#projection_clipExtent). This is the planar equivalent of [d3.geoBounds](#geoBounds). - -# path.centroid(object) [<>](https://github.com/d3/d3-geo/blob/master/src/path/centroid.js "Source") - -Returns the projected planar centroid (typically in pixels) for the specified GeoJSON *object*. This is handy for, say, labeling state or county boundaries, or displaying a symbol map. For example, a [noncontiguous cartogram](https://bl.ocks.org/mbostock/4055908) might scale each state around its centroid. This method observes any clipping performed by the [projection](#path_projection); see [*projection*.clipAngle](#projection_clipAngle) and [*projection*.clipExtent](#projection_clipExtent). This is the planar equivalent of [d3.geoCentroid](#geoCentroid). - -# path.measure(object) [<>](https://github.com/d3/d3-geo/blob/master/src/path/measure.js "Source") - -Returns the projected planar length (typically in pixels) for the specified GeoJSON *object*. Point and MultiPoint geometries have zero length. For Polygon and MultiPolygon geometries, this method computes the summed length of all rings. This method observes any clipping performed by the [projection](#path_projection); see [*projection*.clipAngle](#projection_clipAngle) and [*projection*.clipExtent](#projection_clipExtent). This is the planar equivalent of [d3.geoLength](#geoLength). - -# path.projection([projection]) [<>](https://github.com/d3/d3-geo/blob/master/src/path/index.js "Source") - -If a *projection* is specified, sets the current projection to the specified projection. If *projection* is not specified, returns the current projection, which defaults to null. The null projection represents the identity transformation: the input geometry is not projected and is instead rendered directly in raw coordinates. This can be useful for fast rendering of [pre-projected geometry](https://bl.ocks.org/mbostock/5557726), or for fast rendering of the equirectangular projection. - -The given *projection* is typically one of D3’s built-in [geographic projections](#projections); however, any object that exposes a [*projection*.stream](#projection_stream) function can be used, enabling the use of [custom projections](https://bl.ocks.org/mbostock/5663666). See D3’s [transforms](#transforms) for more examples of arbitrary geometric transformations. - -# path.context([context]) [<>](https://github.com/d3/d3-geo/blob/master/src/path/index.js "Source") - -If *context* is specified, sets the current render context and returns the path generator. If the *context* is null, then the [path generator](#_path) will return an SVG path string; if the context is non-null, the path generator will instead call methods on the specified context to render geometry. The context must implement the following subset of the [CanvasRenderingContext2D API](https://www.w3.org/TR/2dcontext/#canvasrenderingcontext2d): - -* *context*.beginPath() -* *context*.moveTo(*x*, *y*) -* *context*.lineTo(*x*, *y*) -* *context*.arc(*x*, *y*, *radius*, *startAngle*, *endAngle*) -* *context*.closePath() - -If a *context* is not specified, returns the current render context which defaults to null. - -# path.pointRadius([radius]) [<>](https://github.com/d3/d3-geo/blob/master/src/path/index.js "Source") - -If *radius* is specified, sets the radius used to display Point and MultiPoint geometries to the specified number. If *radius* is not specified, returns the current radius accessor, which defaults to 4.5. While the radius is commonly specified as a number constant, it may also be specified as a function which is computed per feature, being passed the any arguments passed to the [path generator](#_path). For example, if your GeoJSON data has additional properties, you might access those properties inside the radius function to vary the point size; alternatively, you could [d3.symbol](https://github.com/d3/d3-shape#symbols) and a [projection](#geoProjection) for greater flexibility. - -### Projections - -Projections transform spherical polygonal geometry to planar polygonal geometry. D3 provides implementations of several classes of standard projections: - -* [Azimuthal](#azimuthal-projections) -* [Composite](#composite-projections) -* [Conic](#conic-projections) -* [Cylindrical](#cylindrical-projections) - -For many more projections, see [d3-geo-projection](https://github.com/d3/d3-geo-projection). You can implement [custom projections](#raw-projections) using [d3.geoProjection](#geoProjection) or [d3.geoProjectionMutator](#geoProjectionMutator). - -# projection(point) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -Returns a new array \[*x*, *y*\] (typically in pixels) representing the projected point of the given *point*. The point must be specified as a two-element array \[*longitude*, *latitude*\] in degrees. May return null if the specified *point* has no defined projected position, such as when the point is outside the clipping bounds of the projection. - -# projection.invert(point) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -Returns a new array \[*longitude*, *latitude*\] in degrees representing the unprojected point of the given projected *point*. The point must be specified as a two-element array \[*x*, *y*\] (typically in pixels). May return null if the specified *point* has no defined projected position, such as when the point is outside the clipping bounds of the projection. - -This method is only defined on invertible projections. - -# projection.stream(stream) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -Returns a [projection stream](#streams) for the specified output *stream*. Any input geometry is projected before being streamed to the output stream. A typical projection involves several geometry transformations: the input geometry is first converted to radians, rotated on three axes, clipped to the small circle or cut along the antimeridian, and lastly projected to the plane with adaptive resampling, scale and translation. - -# projection.preclip([preclip]) - -If *preclip* is specified, sets the projection’s spherical clipping to the specified function and returns the projection. If *preclip* is not specified, returns the current spherical clipping function (see [preclip](#preclip)). - -# projection.postclip([postclip]) - -If *postclip* is specified, sets the projection’s cartesian clipping to the specified function and returns the projection. If *postclip* is not specified, returns the current cartesian clipping function (see [postclip](#postclip)). - -# projection.clipAngle([angle]) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -If *angle* is specified, sets the projection’s clipping circle radius to the specified angle in degrees and returns the projection. If *angle* is null, switches to [antimeridian cutting](https://bl.ocks.org/mbostock/3788999) rather than small-circle clipping. If *angle* is not specified, returns the current clip angle which defaults to null. Small-circle clipping is independent of viewport clipping via [*projection*.clipExtent](#projection_clipExtent). - -See also [*projection*.preclip](#projection_preclip), [d3.geoClipAntimeridian](#geoClipAntimeridian), [d3.geoClipCircle](#geoClipCircle). - -# projection.clipExtent([extent]) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -If *extent* is specified, sets the projection’s viewport clip extent to the specified bounds in pixels and returns the projection. The *extent* bounds are specified as an array \[\[x₀, y₀\], \[x₁, y₁\]\], where x₀ is the left-side of the viewport, y₀ is the top, x₁ is the right and y₁ is the bottom. If *extent* is null, no viewport clipping is performed. If *extent* is not specified, returns the current viewport clip extent which defaults to null. Viewport clipping is independent of small-circle clipping via [*projection*.clipAngle](#projection_clipAngle). - -See also [*projection*.postclip](#projection_postclip), [d3.geoClipRectangle](#geoClipRectangle). - -# projection.scale([scale]) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -If *scale* is specified, sets the projection’s scale factor to the specified value and returns the projection. If *scale* is not specified, returns the current scale factor; the default scale is projection-specific. The scale factor corresponds linearly to the distance between projected points; however, absolute scale factors are not equivalent across projections. - -# projection.translate([translate]) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -If *translate* is specified, sets the projection’s translation offset to the specified two-element array [tx, ty] and returns the projection. If *translate* is not specified, returns the current translation offset which defaults to [480, 250]. The translation offset determines the pixel coordinates of the projection’s [center](#projection_center). The default translation offset places ⟨0°,0°⟩ at the center of a 960×500 area. - -# projection.center([center]) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -If *center* is specified, sets the projection’s center to the specified *center*, a two-element array of longitude and latitude in degrees and returns the projection. If *center* is not specified, returns the current center, which defaults to ⟨0°,0°⟩. - -# projection.angle([angle]) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -If *angle* is specified, sets the projection’s post-projection planar rotation angle to the specified *angle* in degrees and returns the projection. If *angle* is not specified, returns the projection’s current angle, which defaults to 0°. Note that it may be faster to rotate during rendering (e.g., using [*context*.rotate](https://developer.mozilla.org/docs/Web/API/CanvasRenderingContext2D/rotate)) rather than during projection. - -# projection.rotate([angles]) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -If *rotation* is specified, sets the projection’s [three-axis spherical rotation](https://bl.ocks.org/mbostock/4282586) to the specified *angles*, which must be a two- or three-element array of numbers [*lambda*, *phi*, *gamma*] specifying the rotation angles in degrees about [each spherical axis](https://bl.ocks.org/mbostock/4282586). (These correspond to [yaw, pitch and roll](https://en.wikipedia.org/wiki/Aircraft_principal_axes).) If the rotation angle *gamma* is omitted, it defaults to 0. See also [d3.geoRotation](#geoRotation). If *rotation* is not specified, returns the current rotation which defaults [0, 0, 0]. - -# projection.precision([precision]) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -If *precision* is specified, sets the threshold for the projection’s [adaptive resampling](https://bl.ocks.org/mbostock/3795544) to the specified value in pixels and returns the projection. This value corresponds to the [Douglas–Peucker](https://en.wikipedia.org/wiki/Ramer–Douglas–Peucker_algorithm) distance. If *precision* is not specified, returns the projection’s current resampling precision which defaults to √0.5 ≅ 0.70710… - -# projection.fitExtent(extent, object) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -Sets the projection’s [scale](#projection_scale) and [translate](#projection_translate) to fit the specified GeoJSON *object* in the center of the given *extent*. The extent is specified as an array \[\[x₀, y₀\], \[x₁, y₁\]\], where x₀ is the left side of the bounding box, y₀ is the top, x₁ is the right and y₁ is the bottom.

# d3.geoNaturalEarth1Raw - -[](https://observablehq.com/@d3/natural-earth) - -The [Natural Earth projection](http://www.shadedrelief.com/NE_proj/) is a pseudocylindrical projection designed by Tom Patterson. It is neither conformal nor equal-area, but appealing to the eye for small-scale maps of the whole world. - -### Raw Projections - -Raw projections are point transformation functions that are used to implement custom projections; they typically passed to [d3.geoProjection](#geoProjection) or [d3.geoProjectionMutator](#geoProjectionMutator). They are exposed here to facilitate the derivation of related projections. Raw projections take spherical coordinates \[*lambda*, *phi*\] in radians (not degrees!) and return a point \[*x*, *y*\], typically in the unit square centered around the origin. - -# project(lambda, phi) - -Projects the specified point [lambda, phi] in radians, returning a new point \[*x*, *y*\] in unitless coordinates. - -# project.invert(x, y) - -The inverse of [*project*](#_project). - -# d3.geoProjection(project) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -Constructs a new projection from the specified [raw projection](#_project), *project*. The *project* function takes the *longitude* and *latitude* of a given point in [radians](http://mathworld.wolfram.com/Radian.html), often referred to as *lambda* (λ) and *phi* (φ), and returns a two-element array \[*x*, *y*\] representing its unit projection. The *project* function does not need to scale or translate the point, as these are applied automatically by [*projection*.scale](#projection_scale), [*projection*.translate](#projection_translate), and [*projection*.center](#projection_center). Likewise, the *project* function does not need to perform any spherical rotation, as [*projection*.rotate](#projection_rotate) is applied prior to projection. - -For example, a spherical Mercator projection can be implemented as: - -```js -var mercator = d3.geoProjection(function(x, y) { - return [x, Math.log(Math.tan(Math.PI / 4 + y / 2))]; -}); -``` - -If the *project* function exposes an *invert* method, the returned projection will also expose [*projection*.invert](#projection_invert). - -# d3.geoProjectionMutator(factory) [<>](https://github.com/d3/d3-geo/blob/master/src/projection/index.js "Source") - -Constructs a new projection from the specified [raw projection](#_project) *factory* and returns a *mutate* function to call whenever the raw projection changes. The *factory* must return a raw projection. The returned *mutate* function returns the wrapped projection. For example, a conic projection typically has two configurable parallels. A suitable *factory* function, such as [d3.geoConicEqualAreaRaw](#geoConicEqualAreaRaw), would have the form: - -```js -// y0 and y1 represent two parallels -function conicFactory(phi0, phi1) { - return function conicRaw(lambda, phi) { - return […, …]; - }; -} -``` - -Using d3.geoProjectionMutator, you can implement a standard projection that allows the parallels to be changed, reassigning the raw projection used internally by [d3.geoProjection](#geoProjection): - -```js -function conicCustom() { - var phi0 = 29.5, - phi1 = 45.5, - mutate = d3.geoProjectionMutator(conicFactory), - projection = mutate(phi0, phi1); - - projection.parallels = function(_) { - return arguments.length ? mutate(phi0 = +_[0], phi1 = +_[1]) : [phi0, phi1]; - }; - - return projection; -} -``` - -When creating a mutable projection, the *mutate* function is typically not exposed. - -### Spherical Math - -# d3.geoArea(object) [<>](https://github.com/d3/d3-geo/blob/master/src/area.js "Source") - -Returns the spherical area of the specified GeoJSON *object* in [steradians](http://mathworld.wolfram.com/Steradian.html). This is the spherical equivalent of [*path*.area](#path_area). - -# d3.geoBounds(object) [<>](https://github.com/d3/d3-geo/blob/master/src/bounds.js "Source") - -Returns the [spherical bounding box](https://www.jasondavies.com/maps/bounds/) for the specified GeoJSON *object*. The bounding box is represented by a two-dimensional array: \[\[*left*, *bottom*], \[*right*, *top*\]\], where *left* is the minimum longitude, *bottom* is the minimum latitude, *right* is maximum longitude, and *top* is the maximum latitude. All coordinates are given in degrees. (Note that in projected planar coordinates, the minimum latitude is typically the maximum *y*-value, and the maximum latitude is typically the minimum *y*-value.) This is the spherical equivalent of [*path*.bounds](#path_bounds). - -# d3.geoCentroid(object) [<>](https://github.com/d3/d3-geo/blob/master/src/centroid.js "Source") - -Returns the spherical centroid of the specified GeoJSON *object*. This is the spherical equivalent of [*path*.centroid](#path_centroid). - -# d3.geoDistance(a, b) [<>](https://github.com/d3/d3-geo/blob/master/src/distance.js "Source") - -Returns the great-arc distance in [radians](http://mathworld.wolfram.com/Radian.html) between the two points *a* and *b*. Each point must be specified as a two-element array \[*longitude*, *latitude*\] in degrees. This is the spherical equivalent of [*path*.measure](#path_measure) given a LineString of two points. - -# d3.geoLength(object) [<>](https://github.com/d3/d3-geo/blob/master/src/length.js "Source") - -Returns the great-arc length of the specified GeoJSON *object* in [radians](http://mathworld.wolfram.com/Radian.html). For polygons, returns the perimeter of the exterior ring plus that of any interior rings. This is the spherical equivalent of [*path*.measure](#path_measure). - -# d3.geoInterpolate(a, b) [<>](https://github.com/d3/d3-geo/blob/master/src/interpolate.js "Source") - -Returns an interpolator function given two points *a* and *b*. Each point must be specified as a two-element array \[*longitude*, *latitude*\] in degrees. The returned interpolator function takes a single argument *t*, where *t* is a number ranging from 0 to 1; a value of 0 returns the point *a*, while a value of 1 returns the point *b*. Intermediate values interpolate from *a* to *b* along the great arc that passes through both *a* and *b*. If *a* and *b* are antipodes, an arbitrary great arc is chosen. - -# d3.geoContains(object, point) [<>](https://github.com/d3/d3-geo/blob/master/src/contains.js "Source") - -Returns true if and only if the specified GeoJSON *object* contains the specified *point*, or false if the *object* does not contain the *point*. The point must be specified as a two-element array \[*longitude*, *latitude*\] in degrees. For Point and MultiPoint geometries, an exact test is used; for a Sphere, true is always returned; for other geometries, an epsilon threshold is applied. - -# d3.geoRotation(angles) [<>](https://github.com/d3/d3-geo/blob/master/src/rotation.js "Source") - -Returns a [rotation function](#_rotation) for the given *angles*, which must be a two- or three-element array of numbers [*lambda*, *phi*, *gamma*] specifying the rotation angles in degrees about [each spherical axis](https://bl.ocks.org/mbostock/4282586). (These correspond to [yaw, pitch and roll](https://en.wikipedia.org/wiki/Aircraft_principal_axes).) If the rotation angle *gamma* is omitted, it defaults to 0. See also [*projection*.rotate](#projection_rotate). - -# rotation(point) [<>](https://github.com/d3/d3-geo/blob/master/src/rotation.js "Source") - -Returns a new array \[*longitude*, *latitude*\] in degrees representing the rotated point of the given *point*. The point must be specified as a two-element array \[*longitude*, *latitude*\] in degrees. - -# rotation.invert(point) [<>](https://github.com/d3/d3-geo/blob/master/src/rotation.js "Source") - -Returns a new array \[*longitude*, *latitude*\] in degrees representing the point of the given rotated *point*; the inverse of [*rotation*](#_rotation). The point must be specified as a two-element array \[*longitude*, *latitude*\] in degrees. - -### Spherical Shapes - -To generate a [great arc](https://en.wikipedia.org/wiki/Great-circle_distance) (a segment of a great circle), simply pass a GeoJSON LineString geometry object to a [d3.geoPath](#geoPath). D3’s projections use great-arc interpolation for intermediate points, so there’s no need for a great arc shape generator. - -# d3.geoCircle() [<>](https://github.com/d3/d3-geo/blob/master/src/circle.js "Source") - -Returns a new circle generator. - -# circle(arguments…) [<>](https://github.com/d3/d3-geo/blob/master/src/circle.js "Source") - -Returns a new GeoJSON geometry object of type “Polygon” approximating a circle on the surface of a sphere, with the current [center](#circle_center), [radius](#circle_radius) and [precision](#circle_precision). Any *arguments* are passed to the accessors. - -# circle.center([center]) [<>](https://github.com/d3/d3-geo/blob/master/src/circle.js "Source") - -If *center* is specified, sets the circle center to the specified point \[*longitude*, *latitude*\] in degrees, and returns this circle generator. The center may also be specified as a function; this function will be invoked whenever a circle is [generated](#_circle), being passed any arguments passed to the circle generator. If *center* is not specified, returns the current center accessor, which defaults to: - -```js -function center() { - return [0, 0]; -} -``` - -# circle.radius([radius]) [<>](https://github.com/d3/d3-geo/blob/master/src/circle.js "Source") - -If *radius* is specified, sets the circle radius to the specified angle in degrees, and returns this circle generator. The radius may also be specified as a function; this function will be invoked whenever a circle is [generated](#_circle), being passed any arguments passed to the circle generator. If *radius* is not specified, returns the current radius accessor, which defaults to: - -```js -function radius() { - return 90; -} -``` - -# circle.precision([angle]) [<>](https://github.com/d3/d3-geo/blob/master/src/circle.js "Source") - -If *precision* is specified, sets the circle precision to the specified angle in degrees, and returns this circle generator.

If *precision* is not specified, returns the current precision accessor, which defaults to: - -```js -function precision() { - return 6; -} -``` - -Small circles do not follow great arcs and thus the generated polygon is only an approximation. Specifying a smaller precision angle improves the accuracy of the approximate polygon, but also increase the cost to generate and render it. - -# d3.geoGraticule() [<>](https://github.com/d3/d3-geo/blob/master/src/graticule.js "Source") - -Constructs a geometry generator for creating graticules: a uniform grid of [meridians](https://en.wikipedia.org/wiki/Meridian_\(geography\)) and [parallels](https://en.wikipedia.org/wiki/Circle_of_latitude) for showing projection distortion.

Equivalent to: - -```js -function geoGraticule10() { - return d3.geoGraticule()(); -} -``` - -### Streams - -D3 transforms geometry using a sequence of function calls, rather than materializing intermediate representations, to minimize overhead. Streams must implement several methods to receive input geometry. Streams are inherently stateful; the meaning of a [point](#point) depends on whether the point is inside of a [line](#lineStart), and likewise a line is distinguished from a ring by a [polygon](#polygonStart). Despite the name “stream”, these method calls are currently synchronous. - -# d3.geoStream(object, stream) [<>](https://github.com/d3/d3-geo/blob/master/src/stream.js "Source") - -Streams the specified [GeoJSON](http://geojson.org) *object* to the specified [projection *stream*](#projection-streams). While both features and geometry objects are supported as input, the stream interface only describes the geometry, and thus additional feature properties are not visible to streams. - -# stream.point(x, y[, z]) - -Indicates a point with the specified coordinates *x* and *y* (and optionally *z*). The coordinate system is unspecified and implementation-dependent; for example, [projection streams](https://github.com/d3/d3-geo-projection) require spherical coordinates in degrees as input. Outside the context of a polygon or line, a point indicates a point geometry object ([Point](http://www.geojson.org/geojson-spec.html#point) or [MultiPoint](http://www.geojson.org/geojson-spec.html#multipoint)). Within a line or polygon ring, the point indicates a control point. - -# stream.lineStart() - -Indicates the start of a line or ring. Within a polygon, indicates the start of a ring. The first ring of a polygon is the exterior ring, and is typically clockwise. Any subsequent rings indicate holes in the polygon, and are typically counterclockwise. - -# stream.lineEnd() - -Indicates the end of a line or ring. Within a polygon, indicates the end of a ring. Unlike GeoJSON, the redundant closing coordinate of a ring is *not* indicated via [point](#point), and instead is implied via lineEnd within a polygon. Thus, the given polygon input: - -```json -{ - "type": "Polygon", - "coordinates": [ - [[0, 0], [0, 1], [1, 1], [1, 0], [0, 0]] - ] -} -``` - -Will produce the following series of method calls on the stream: - -```js -stream.polygonStart(); -stream.lineStart(); -stream.point(0, 0); -stream.point(0, 1); -stream.point(1, 1); -stream.point(1, 0); -stream.lineEnd(); -stream.polygonEnd(); -``` - -# stream.polygonStart() - -Indicates the start of a polygon. The first line of a polygon indicates the exterior ring, and any subsequent lines indicate interior holes. - -# stream.polygonEnd() - -Indicates the end of a polygon. - -# stream.sphere() - -Indicates the sphere (the globe; the unit sphere centered at ⟨0,0,0⟩). - -### Transforms - -Transforms are a generalization of projections. Transform implement [*projection*.stream](#projection_stream) and can be passed to [*path*.projection](#path_projection). However, they only implement a subset of the other projection methods, and represent arbitrary geometric transformations rather than projections from spherical to planar coordinates. - -# d3.geoTransform(methods) [<>](https://github.com/d3/d3-geo/blob/master/src/transform.js "Source") - -Defines an arbitrary transform using the methods defined on the specified *methods* object. Any undefined methods will use pass-through methods that propagate inputs to the output stream. For example, to reflect the *y*-dimension (see also [*identity*.reflectY](#identity_reflectY)): - -```js -var reflectY = d3.geoTransform({ - point: function(x, y) { - this.stream.point(x, -y); - } -}); -``` - -Or to define an affine matrix transformation: - -```js -function matrix(a, b, c, d, tx, ty) { - return d3.geoTransform({ - point: function(x, y) { - this.stream.point(a * x + b * y + tx, c * x + d * y + ty); - } - }); -} -``` - -# d3.geoIdentity() [<>](https://github.com/d3/d3-geo/blob/master/src/projection/identity.js "Source") - -The identity transform can be used to scale, translate and clip planar geometry. It implements [*projection*.scale](#projection_scale), [*projection*.translate](#projection_translate), [*projection*.fitExtent](#projection_fitExtent), [*projection*.fitSize](#projection_fitSize), [*projection*.fitWidth](#projection_fitWidth), [*projection*.fitHeight](#projection_fitHeight) and [*projection*.clipExtent](#projection_clipExtent). - -# identity.reflectX([reflect]) - -If *reflect* is specified, sets whether or not the *x*-dimension is reflected (negated) in the output. If *reflect* is not specified, returns true if *x*-reflection is enabled, which defaults to false. - -# identity.reflectY([reflect]) - -If *reflect* is specified, sets whether or not the *y*-dimension is reflected (negated) in the output. If *reflect* is not specified, returns true if *y*-reflection is enabled, which defaults to false. This is especially useful for transforming from standard [spatial reference systems](https://en.wikipedia.org/wiki/Spatial_reference_system), which treat positive *y* as pointing up, to display coordinate systems such as Canvas and SVG, which treat positive *y* as pointing down. - -### Clipping - -Projections perform cutting or clipping of geometries in two stages. - -# preclip(stream) - -Pre-clipping occurs in geographic coordinates. Cutting along the antimeridian line, or clipping along a small circle are the most common strategies. - -See [*projection*.preclip](#projection_preclip). - -# postclip(stream) - -Post-clipping occurs on the plane, when a projection is bounded to a certain extent such as a rectangle. - -See [*projection*.postclip](#projection_postclip). - -Clipping functions are implemented as transformations of a [projection stream](#streams). Pre-clipping operates on spherical coordinates, in radians. Post-clipping operates on planar coordinates, in pixels. - -# d3.geoClipAntimeridian - -A clipping function which transforms a stream such that geometries (lines or polygons) that cross the antimeridian line are cut in two, one on each side.

[Indented trees](https://bl.ocks.org/mbostock/1093025) are useful for interactive browsing. - -**Adjacency diagrams** show topology through the relative placement of nodes. They may also encode a quantitative dimension in the area of each node, for example to show revenue or file size. The [“icicle” diagram](#partition) uses rectangles, while the “sunburst” uses annular segments. - -**Enclosure diagrams** also use an area encoding, but show topology through containment. A [treemap](#treemap) recursively subdivides area into rectangles.

If *a* should be before *b*, the function must return a value less than zero; if *b* should be before *a*, the function must return a value greater than zero; otherwise, the relative order of *a* and *b* are not specified. See [*array*.sort](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort) for more. - -Unlike [*node*.sum](#node_sum), the *compare* function is passed two [nodes](#hierarchy) rather than two nodes’ data.

D3’s treemap implementation supports an extensible [tiling method](#treemap_tile): the default [squarified](#treemapSquarify) method seeks to generate rectangles with a [golden](https://en.wikipedia.org/wiki/Golden_ratio) aspect ratio; this offers better readability and size estimation than [slice-and-dice](#treemapSliceDice), which simply alternates between horizontal and vertical subdivision by depth. - -# d3.treemap() · [Source](https://github.com/d3/d3-hierarchy/blob/master/src/treemap/index.js), [Examples](https://observablehq.com/@d3/treemap) - -Creates a new treemap layout with default settings. - -# treemap(root) - -Lays out the specified *root* [hierarchy](#hierarchy), assigning the following properties on *root* and its descendants: - -* *node*.x0 - the left edge of the rectangle -* *node*.y0 - the top edge of the rectangle -* *node*.x1 - the right edge of the rectangle -* *node*.y1 - the bottom edge of the rectangle - -You must call [*root*.sum](#node_sum) before passing the hierarchy to the treemap layout.

The children are positioned in order, starting with the left edge (*x0*) of the given rectangle. If the sum of the children’s values is less than the specified *node*’s value (*i.e.*, if the specified *node* has a non-zero internal value), the remaining empty space will be positioned on the right edge (*x1*) of the given rectangle. - -# d3.treemapSlice(node, x0, y0, x1, y1) · [Source](https://github.com/d3/d3-hierarchy/blob/master/src/treemap/slice.js), [Examples](https://observablehq.com/@d3/treemap) - -Divides the rectangular area specified by *x0*, *y0*, *x1*, *y1* vertically according the value of each of the specified *node*’s children.

This tiling method is good for animating changes to treemaps because it only changes node sizes and not their relative positions, thus avoiding distracting shuffling and occlusion. The downside of a stable update, however, is a suboptimal layout for subsequent updates: only the first layout uses the Bruls *et al.* squarified algorithm. - -# squarify.ratio(ratio) · [Source](https://github.com/d3/d3-hierarchy/blob/master/src/treemap/squarify.js), [Examples](https://observablehq.com/@d3/treemap) - -Specifies the desired aspect ratio of the generated rectangles. The *ratio* must be specified as a number greater than or equal to one. Note that the orientation of the generated rectangles (tall or wide) is not implied by the ratio; for example, a ratio of two will attempt to produce a mixture of rectangles whose *width*:*height* ratio is either 2:1 or 1:2. (However, you can approximately achieve this result by generating a square treemap at different dimensions, and then [stretching the treemap](https://observablehq.com/@d3/stretched-treemap) to the desired aspect ratio.) Furthermore, the specified *ratio* is merely a hint to the tiling algorithm; the rectangles are not guaranteed to have the specified aspect ratio. If not specified, the aspect ratio defaults to the golden ratio, φ = (1 + sqrt(5)) / 2, per [Kong *et al.*](http://vis.stanford.edu/papers/perception-treemaps) - -### Partition - -[Partition](https://observablehq.com/@d3/icicle) - -The **partition layout** produces adjacency diagrams: a space-filling variant of a node-link tree diagram. Rather than drawing a link between parent and child in the hierarchy, nodes are drawn as solid areas (either arcs or rectangles), and their placement relative to other nodes reveals their position in the hierarchy. The size of the nodes encodes a quantitative dimension that would be difficult to show in a node-link diagram. - -# d3.partition() · [Source](https://github.com/d3/d3-hierarchy/blob/master/src/partition.js), [Examples](https://observablehq.com/@d3/icicle) - -Creates a new partition layout with the default settings. - -# partition(root) - -Lays out the specified *root* [hierarchy](#hierarchy), assigning the following properties on *root* and its descendants: - -* *node*.x0 - the left edge of the rectangle -* *node*.y0 - the top edge of the rectangle -* *node*.x1 - the right edge of the rectangle -* *node*.y1 - the bottom edge of the rectangle - -You must call [*root*.sum](#node_sum) before passing the hierarchy to the partition layout.

If *padding* is not specified, returns the current padding, which defaults to zero. The padding is used to separate a node’s adjacent children. - -### Pack - -[Circle-Packing](https://observablehq.com/@d3/circle-packing) - -Enclosure diagrams use containment (nesting) to represent a hierarchy. The size of the leaf circles encodes a quantitative dimension of the data. The enclosing circles show the approximate cumulative size of each subtree, but due to wasted space there is some distortion; only the leaf nodes can be compared accurately. Although [circle packing](http://en.wikipedia.org/wiki/Circle_packing) does not use space as efficiently as a [treemap](#treemap), the “wasted” space more prominently reveals the hierarchical structure. - -# d3.pack() · [Source](https://github.com/d3/d3-hierarchy/blob/master/src/pack/index.js), [Examples](https://observablehq.com/@d3/circle-packing) - -Creates a new pack layout with the default settings. - -# pack(root) - -Lays out the specified *root* [hierarchy](#hierarchy), assigning the following properties on *root* and its descendants: - -* *node*.x - the *x*-coordinate of the circle’s center -* *node*.y - the *y*-coordinate of the circle’s center -* *node*.r - the radius of the circle - -You must call [*root*.sum](#node_sum) before passing the hierarchy to the pack layout.

If *radius* is not specified, returns the current radius accessor, which defaults to null. If the radius accessor is null, the radius of each leaf circle is derived from the leaf *node*.value (computed by [*node*.sum](#node_sum)); the radii are then scaled proportionally to fit the [layout size](#pack_size). If the radius accessor is not null, the radius of each leaf circle is specified exactly by the function. - -# pack.size([size]) - -If *size* is specified, sets this pack layout’s size to the specified two-element array of numbers [*width*, *height*] and returns this pack layout. If *size* is not specified, returns the current size, which defaults to [1, 1]. - -# pack.padding([padding]) - -If *padding* is specified, sets this pack layout’s padding accessor to the specified number or function and returns this pack layout. If *padding* is not specified, returns the current padding accessor, which defaults to the constant zero. When siblings are packed, tangent siblings will be separated by approximately the specified padding; the enclosing parent circle will also be separated from its children by approximately the specified padding. If an [explicit radius](#pack_radius) is not specified, the padding is approximate because a two-pass algorithm is needed to fit within the [layout size](#pack_size): the circles are first packed without padding; a scaling factor is computed and applied to the specified padding; and lastly the circles are re-packed with padding. - -# d3.packSiblings(circles) · [Source](https://github.com/d3/d3-hierarchy/blob/master/src/pack/siblings.js) - -Packs the specified array of *circles*, each of which must have a *circle*.r property specifying the circle’s radius.

Nuij. Each view is defined as an array of three numbers: *cx*, *cy* and *width*. The first two coordinates *cx*, *cy* represent the center of the viewport; the last coordinate *width* represents the size of the viewport. - -The returned interpolator exposes a *duration* property which encodes the recommended transition duration in milliseconds. This duration is based on the path length of the curved trajectory through *x,y* space.

For example: - -```js -var d3 = require("d3-random"), - seedrandom = require("seedrandom"), - random = d3.randomNormal.source(seedrandom("a22ebc7c488a3a47"))(0, 1); - -random(); // 0.9744193494813501 -``` diff --git a/node_modules/d3-random/dist/d3-random.js b/node_modules/d3-random/dist/d3-random.js deleted file mode 100644 index 78640cec7aee449b8889b1e9a4e3a8c5a9acfce5..0000000000000000000000000000000000000000 --- a/node_modules/d3-random/dist/d3-random.js +++ /dev/null @@ -1,115 +0,0 @@ -// https://d3js.org/d3-random/ v1.1.2 Copyright 2018 Mike Bostock -(function (global, factory) { -typeof exports === 'object' && typeof module !== 'undefined' ? factory(exports) : -typeof define === 'function' && define.amd ? define(['exports'], factory) : -(factory((global.d3 = global.d3 || {})));

Most of these schemes are derived from Cynthia A. Brewer’s [ColorBrewer](http://colorbrewer2.org). Since ColorBrewer publishes only discrete color schemes, the sequential and diverging scales are interpolated using [uniform B-splines](https://bl.ocks.org/mbostock/048d21cf747371b11884f75ad896e5a5). - -For example, to create a categorical color scale using the [Accent](#schemeAccent) color scheme: - -```js -var accent = d3.scaleOrdinal(d3.schemeAccent); -``` - -To create a sequential discrete nine-color scale using the [Blues](#schemeBlues) color scheme: - -```js -var blues = d3.scaleOrdinal(d3.schemeBlues[9]); -``` - -To create a diverging, continuous color scale using the [PiYG](#interpolatePiYG) color scheme: - -```js -var piyg = d3.scaleSequential(d3.interpolatePiYG); -``` - -## Installing - -If you use NPM, `npm install d3-scale-chromatic`. Otherwise, download the [latest release](https://github.com/d3/d3-scale-chromatic/releases/latest) or load directly from [d3js.org](https://d3js.org) as a [standalone library](https://d3js.org/d3-scale-chromatic.v1.min.js).

Each discrete scheme, such as [d3.schemeBrBG](#schemeBrBG), is represented as an array of arrays of hexadecimal color strings. The *k*th element of this array contains the color scheme of size *k*; for example, `d3.schemeBrBG[9]` contains an array of nine strings representing the nine colors of the brown-blue-green diverging color scheme. Diverging color schemes support a size *k* ranging from 3 to 11. - -# d3.interpolateBrBG(*t*) [<>](https://github.com/d3/d3-scale-chromatic/blob/master/src/diverging/BrBG.js "Source") -

Although most often used for position-encoding quantitative data, such as mapping a measurement in meters to a position in pixels for dots in a scatterplot, scales can represent virtually any visual encoding, such as diverging colors, stroke widths, or symbol size. Scales can also be used with virtually any type of data, such as named categorical data or discrete data that requires sensible breaks. - -For [continuous](#continuous-scales) quantitative data, you typically want a [linear scale](#linear-scales). (For time series data, a [time scale](#time-scales).) If the distribution calls for it, consider transforming data using a [power](#power-scales) or [log](#log-scales) scale. A [quantize scale](#quantize-scales) may aid differentiation by rounding continuous data to a fixed set of discrete values; similarly, a [quantile scale](#quantile-scales) computes quantiles from a sample population, and a [threshold scale](#threshold-scales) allows you to specify arbitrary breaks in continuous data. - -For discrete ordinal (ordered) or categorical (unordered) data, an [ordinal scale](#ordinal-scales) specifies an explicit mapping from a set of data values to a corresponding set of visual attributes (such as colors). The related [band](#band-scales) and [point](#point-scales) scales are useful for position-encoding ordinal data, such as bars in a bar chart or dots in an categorical scatterplot. - -This repository does not provide color schemes; see [d3-scale-chromatic](https://github.com/d3/d3-scale-chromatic) for color schemes designed to work with d3-scale. - -Scales have no intrinsic visual representation.

If the range is also numeric, the mapping may be [inverted](#continuous_invert). A continuous scale is not constructed directly; instead, try a [linear](#linear-scales), [power](#power-scales), [log](#log-scales), [identity](#identity-scales), [time](#time-scales) or [sequential color](#sequential-scales) scale. - -# continuous(value) [<>](https://github.com/d3/d3-scale/blob/master/src/continuous.js "Source") - -Given a *value* from the [domain](#continuous_domain), returns the corresponding value from the [range](#continuous_range). If the given *value* is outside the domain, and [clamping](#continuous_clamp) is not enabled, the mapping may be extrapolated such that the returned value is outside the range. For example, to apply a position encoding: - -```js -var x = d3.scaleLinear() - .domain([10, 130]) - .range([0, 960]); - -x(20); // 80 -x(50); // 320 -``` - -Or to apply a color encoding: - -```js -var color = d3.scaleLinear() - .domain([10, 100]) - .range(["brown", "steelblue"]); - -color(20); // "#9a3439" -color(50); // "#7b5167" -``` - -Or, in shortand: - -```js -var x = d3.scaleLinear([10, 130], [0, 960]); -var color = d3.scaleLinear([10, 100], ["brown", "steelblue"]); -``` - -# continuous.invert(value) [<>](https://github.com/d3/d3-scale/blob/master/src/continuous.js "Source") - -Given a *value* from the [range](#continuous_range), returns the corresponding value from the [domain](#continuous_domain). Inversion is useful for interaction, say to determine the data value corresponding to the position of the mouse. For example, to invert a position encoding: - -```js -var x = d3.scaleLinear() - .domain([10, 130]) - .range([0, 960]); - -x.invert(80); // 20 -x.invert(320); // 50 -``` - -If the given *value* is outside the range, and [clamping](#continuous_clamp) is not enabled, the mapping may be extrapolated such that the returned value is outside the domain. This method is only supported if the range is numeric. If the range is not numeric, returns NaN. - -For a valid value *y* in the range, continuous(continuous.invert(y)) approximately equals *y*; similarly, for a valid value *x* in the domain, continuous.invert(continuous(x)) approximately equals *x*. The scale and its inverse may not be exact due to the limitations of floating point precision. - -# continuous.domain([domain]) [<>](https://github.com/d3/d3-scale/blob/master/src/continuous.js "Source") - -If *domain* is specified, sets the scale’s domain to the specified array of numbers. The array must contain two or more elements. If the elements in the given array are not numbers, they will be coerced to numbers. If *domain* is not specified, returns a copy of the scale’s current domain. - -Although continuous scales typically have two values each in their domain and range, specifying more than two values produces a piecewise scale. For example, to create a [diverging color scale](#diverging-scales) that interpolates between white and red for negative values, and white and green for positive values, say: - -```js -var color = d3.scaleLinear() - .domain([-1, 0, 1]) - .range(["red", "white", "green"]); - -color(-0.5); // "rgb(255, 128, 128)" -color(+0.5); // "rgb(128, 192, 128)" -``` - -Internally, a piecewise scale performs a [binary search](https://github.com/d3/d3-array#bisect) for the range interpolator corresponding to the given domain value. Thus, the domain must be in ascending or descending order. If the domain and range have different lengths *N* and *M*, only the first *min(N,M)* elements in each are observed. - -# continuous.range([range]) [<>](https://github.com/d3/d3-scale/blob/master/src/continuous.js "Source") - -If *range* is specified, sets the scale’s range to the specified array of values. The array must contain two or more elements. Unlike the [domain](#continuous_domain), elements in the given array need not be numbers; any value that is supported by the underlying [interpolator](#continuous_interpolate) will work, though note that numeric ranges are required for [invert](#continuous_invert). If *range* is not specified, returns a copy of the scale’s current range. See [*continuous*.interpolate](#continuous_interpolate) for more examples. - -# continuous.rangeRound([range]) [<>](https://github.com/d3/d3-scale/blob/master/src/continuous.js "Source") - -Sets the scale’s [*range*](#continuous_range) to the specified array of values while also setting the scale’s [interpolator](#continuous_interpolate) to [interpolateRound](https://github.com/d3/d3-interpolate#interpolateRound). This is a convenience method equivalent to: - -```js -continuous - .range(range) - .interpolate(d3.interpolateRound); -``` - -The rounding interpolator is sometimes useful for avoiding antialiasing artifacts, though also consider the [shape-rendering](https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/shape-rendering) “crispEdges” styles. Note that this interpolator can only be used with numeric ranges. - -# continuous.clamp(clamp) [<>](https://github.com/d3/d3-scale/blob/master/src/continuous.js "Source") - -If *clamp* is specified, enables or disables clamping accordingly. If clamping is disabled and the scale is passed a value outside the [domain](#continuous_domain), the scale may return a value outside the [range](#continuous_range) through extrapolation. If clamping is enabled, the return value of the scale is always within the scale’s range. Clamping similarly applies to [*continuous*.invert](#continuous_invert). For example: - -```js -var x = d3.scaleLinear() - .domain([10, 130]) - .range([0, 960]); - -x(-10); // -160, outside range -x.invert(-160); // -10, outside domain - -x.clamp(true); -x(-10); // 0, clamped to range -x.invert(-160); // 10, clamped to domain -``` - -If *clamp* is not specified, returns whether or not the scale currently clamps values to within the range. - -# continuous.unknown([value]) [<>](https://github.com/d3/d3-scale/blob/master/src/continuous.js "Source") - -If *value* is specified, sets the output value of the scale for undefined (or NaN) input values and returns this scale. If *value* is not specified, returns the current unknown value, which defaults to undefined. - -# continuous.interpolate(interpolate) [<>](https://github.com/d3/d3-scale/blob/master/src/continuous.js "Source") - -If *interpolate* is specified, sets the scale’s [range](#continuous_range) interpolator factory. This interpolator factory is used to create interpolators for each adjacent pair of values from the range; these interpolators then map a normalized domain parameter *t* in [0, 1] to the corresponding value in the range. If *factory* is not specified, returns the scale’s current interpolator factory, which defaults to [interpolate](https://github.com/d3/d3-interpolate#interpolate). See [d3-interpolate](https://github.com/d3/d3-interpolate) for more interpolators. - -For example, consider a diverging color scale with three colors in the range: - -```js -var color = d3.scaleLinear() - .domain([-100, 0, +100]) - .range(["red", "white", "green"]); -``` - -Two interpolators are created internally by the scale, equivalent to: - -```js -var i0 = d3.interpolate("red", "white"), - i1 = d3.interpolate("white", "green"); -``` - -A common reason to specify a custom interpolator is to change the color space of interpolation. For example, to use [HCL](https://github.com/d3/d3-interpolate#interpolateHcl): - -```js -var color = d3.scaleLinear() - .domain([10, 100]) - .range(["brown", "steelblue"]) - .interpolate(d3.interpolateHcl); -``` - -Or for [Cubehelix](https://github.com/d3/d3-interpolate#interpolateCubehelix) with a custom gamma: - -```js -var color = d3.scaleLinear() - .domain([10, 100]) - .range(["brown", "steelblue"]) - .interpolate(d3.interpolateCubehelix.gamma(3)); -``` - -Note: the [default interpolator](https://github.com/d3/d3-interpolate#interpolate) **may reuse return values**. For example, if the range values are objects, then the value interpolator always returns the same object, modifying it in-place. If the scale is used to set an attribute or style, this is typically acceptable (and desirable for performance); however, if you need to store the scale’s return value, you must specify your own interpolator or make a copy as appropriate. - -# continuous.ticks([count]) - -Returns approximately *count* representative values from the scale’s [domain](#continuous_domain). If *count* is not specified, it defaults to 10. The returned tick values are uniformly spaced, have human-readable values (such as multiples of powers of 10), and are guaranteed to be within the extent of the domain. Ticks are often used to display reference lines, or tick marks, in conjunction with the visualized data. The specified *count* is only a hint; the scale may return more or fewer values depending on the domain. See also d3-array’s [ticks](https://github.com/d3/d3-array#ticks). - -# continuous.tickFormat([count[, specifier]]) [<>](https://github.com/d3/d3-scale/blob/master/src/tickFormat.js "Source") - -Returns a [number format](https://github.com/d3/d3-format) function suitable for displaying a tick value, automatically computing the appropriate precision based on the fixed interval between tick values. The specified *count* should have the same value as the count that is used to generate the [tick values](#continuous_ticks). - -An optional *specifier* allows a [custom format](https://github.com/d3/d3-format#locale_format) where the precision of the format is automatically set by the scale as appropriate for the tick interval. For example, to format percentage change, you might say: - -```js -var x = d3.scaleLinear() - .domain([-1, 1]) - .range([0, 960]); - -var ticks = x.ticks(5), - tickFormat = x.tickFormat(5, "+%"); - -ticks.map(tickFormat); // ["-100%", "-50%", "+0%", "+50%", "+100%"] -``` - -If *specifier* uses the format type `s`, the scale will return a [SI-prefix format](https://github.com/d3/d3-format#locale_formatPrefix) based on the largest value in the domain. If the *specifier* already specifies a precision, this method is equivalent to [*locale*.format](https://github.com/d3/d3-format#locale_format). - -See also [d3.tickFormat](#tickFormat). - -# continuous.nice([count]) [<>](https://github.com/d3/d3-scale/blob/master/src/nice.js "Source") - -Extends the [domain](#continuous_domain) so that it starts and ends on nice round values. This method typically modifies the scale’s domain, and may only extend the bounds to the nearest round value. An optional tick *count* argument allows greater control over the step size used to extend the bounds, guaranteeing that the returned [ticks](#continuous_ticks) will exactly cover the domain. Nicing is useful if the domain is computed from data, say using [extent](https://github.com/d3/d3-array#extent), and may be irregular. For example, for a domain of [0.201479…, 0.996679…], a nice domain might be [0.2, 1.0]. If the domain has more than two values, nicing the domain only affects the first and last value. See also d3-array’s [tickStep](https://github.com/d3/d3-array#tickStep). - -Nicing a scale only modifies the current domain; it does not automatically nice domains that are subsequently set using [*continuous*.domain](#continuous_domain). You must re-nice the scale after setting the new domain, if desired. - -# continuous.copy() [<>](https://github.com/d3/d3-scale/blob/master/src/continuous.js "Source") - -Returns an exact copy of this scale. Changes to this scale will not affect the returned scale, and vice versa. - -# d3.tickFormat(start, stop, count[, specifier]) [<>](https://github.com/d3/d3-scale/blob/master/src/tickFormat.js "Source") - -Returns a [number format](https://github.com/d3/d3-format) function suitable for displaying a tick value, automatically computing the appropriate precision based on the fixed interval between tick values, as determined by [d3.tickStep](https://github.com/d3/d3-array/blob/master/README.md#tickStep). - -An optional *specifier* allows a [custom format](https://github.com/d3/d3-format#locale_format) where the precision of the format is automatically set by the scale as appropriate for the tick interval. For example, to format percentage change, you might say: - -```js -var tickFormat = d3.tickFormat(-1, 1, 5, "+%"); - -tickFormat(-0.5); // "-50%" -``` - -If *specifier* uses the format type `s`, the scale will return a [SI-prefix format](https://github.com/d3/d3-format#locale_formatPrefix) based on the larger absolute value of *start* and *stop*. If the *specifier* already specifies a precision, this method is equivalent to [*locale*.format](https://github.com/d3/d3-format#locale_format). - -#### Linear Scales - -# d3.scaleLinear([[domain, ]range]) [<>](https://github.com/d3/d3-scale/blob/master/src/linear.js "Source") - -Constructs a new [continuous scale](#continuous-scales) with the specified [domain](#continuous_domain) and [range](#continuous_range), the [default](https://github.com/d3/d3-interpolate#interpolate) [interpolator](#continuous_interpolate) and [clamping](#continuous_clamp) disabled. If either *domain* or *range* are not specified, each defaults to [0, 1]. Linear scales are a good default choice for continuous quantitative data because they preserve proportional differences. Each range value *y* can be expressed as a function of the domain value *x*: *y* = *mx* + *b*. - -#### Power Scales - -Power scales are similar to [linear scales](#linear-scales), except an exponential transform is applied to the input domain value before the output range value is computed. Each range value *y* can be expressed as a function of the domain value *x*: *y* = *mx^k* + *b*, where *k* is the [exponent](#pow_exponent) value.

The mapping to the range value *y* can be expressed as a function of the domain value *x*: *y* = *m* log(x) + *b*. - -As log(0) = -∞, a log scale domain must be **strictly-positive or strictly-negative**; the domain must not include or cross zero. A log scale with a positive domain has a well-defined behavior for positive values, and a log scale with a negative domain has a well-defined behavior for negative values. (For a negative domain, input and output values are implicitly multiplied by -1.)

The returned ticks are guaranteed to be within the extent of the domain. If the orders of magnitude in the [domain](#log_domain) is greater than *count*, then at most one tick per power is returned. Otherwise, the tick values are unfiltered, but note that you can use [*log*.tickFormat](#log_tickFormat) to filter the display of tick labels. If *count* is not specified, it defaults to 10. - -# log.tickFormat([count[, specifier]]) [<>](https://github.com/d3/d3-scale/blob/master/src/log.js "Source") - -Like [*continuous*.tickFormat](#continuous_tickFormat), but customized for a log scale. The specified *count* typically has the same value as the count that is used to generate the [tick values](#continuous_ticks). If there are too many ticks, the formatter may return the empty string for some of the tick labels; however, note that the ticks are still shown. To disable filtering, specify a *count* of Infinity. When specifying a count, you may also provide a format *specifier* or format function. For example, to get a tick formatter that will display 20 ticks of a currency, say `log.tickFormat(20, "$,f")`.

See “A bi-symmetric log transformation for wide-range data” by Webber for more. - -#### Identity Scales - -Identity scales are a special case of [linear scales](#linear-scales) where the domain and range are identical; the scale and its invert method are thus the identity function. These scales are occasionally useful when working with pixel coordinates, say in conjunction with an axis or brush. Identity scales do not support [rangeRound](#continuous_rangeRound), [clamp](#continuous_clamp) or [interpolate](#continuous_interpolate). - -# d3.scaleIdentity([range]) [<>](https://github.com/d3/d3-scale/blob/master/src/identity.js "Source") - -Constructs a new identity scale with the specified [domain](#continuous_domain) and [range](#continuous_range). If *range* is not specified, it defaults to [0, 1]. - -#### Time Scales - -Time scales are a variant of [linear scales](#linear-scales) that have a temporal domain: domain values are coerced to [dates](https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Date) rather than numbers, and [invert](#continuous_invert) likewise returns a date. Time scales implement [ticks](#time_ticks) based on [calendar intervals](https://github.com/d3/d3-time), taking the pain out of generating axes for temporal domains. - -For example, to create a position encoding: - -```js -var x = d3.scaleTime() - .domain([new Date(2000, 0, 1), new Date(2000, 0, 2)]) - .range([0, 960]); - -x(new Date(2000, 0, 1, 5)); // 200 -x(new Date(2000, 0, 1, 16)); // 640 -x.invert(200); // Sat Jan 01 2000 05:00:00 GMT-0800 (PST) -x.invert(640); // Sat Jan 01 2000 16:00:00 GMT-0800 (PST) -``` - -For a valid value *y* in the range, time(time.invert(y)) equals *y*; similarly, for a valid value *x* in the domain, time.invert(time(x)) equals *x*. The invert method is useful for interaction, say to determine the value in the domain that corresponds to the pixel location under the mouse. - -# d3.scaleTime([[domain, ]range]) [<>](https://github.com/d3/d3-scale/blob/master/src/time.js "Source") - -Constructs a new time scale with the specified [domain](#time_domain) and [range](#time_range), the [default](https://github.com/d3/d3-interpolate#interpolate) [interpolator](#time_interpolate) and [clamping](#time_clamp) disabled.

# time.ticks([interval]) - -Returns representative dates from the scale’s [domain](#time_domain). The returned tick values are uniformly-spaced (mostly), have sensible values (such as every day at midnight), and are guaranteed to be within the extent of the domain. Ticks are often used to display reference lines, or tick marks, in conjunction with the visualized data. - -An optional *count* may be specified to affect how many ticks are generated. If *count* is not specified, it defaults to 10. The specified *count* is only a hint; the scale may return more or fewer values depending on the domain. For example, to create ten default ticks, say: - -```js -var x = d3.scaleTime(); - -x.ticks(10); -// [Sat Jan 01 2000 00:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 03:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 06:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 09:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 12:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 15:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 18:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 21:00:00 GMT-0800 (PST), -// Sun Jan 02 2000 00:00:00 GMT-0800 (PST)] -``` - -The following time intervals are considered for automatic ticks: - -* 1-, 5-, 15- and 30-second. -* 1-, 5-, 15- and 30-minute. -* 1-, 3-, 6- and 12-hour. -* 1- and 2-day. -* 1-week. -* 1- and 3-month. -* 1-year. - -In lieu of a *count*, a [time *interval*](https://github.com/d3/d3-time#intervals) may be explicitly specified. To prune the generated ticks for a given time *interval*, use [*interval*.every](https://github.com/d3/d3-time#interval_every). For example, to generate ticks at 15-[minute](https://github.com/d3/d3-time#minute) intervals: - -```js -var x = d3.scaleTime() - .domain([new Date(2000, 0, 1, 0), new Date(2000, 0, 1, 2)]); - -x.ticks(d3.timeMinute.every(15)); -// [Sat Jan 01 2000 00:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 00:15:00 GMT-0800 (PST), -// Sat Jan 01 2000 00:30:00 GMT-0800 (PST), -// Sat Jan 01 2000 00:45:00 GMT-0800 (PST), -// Sat Jan 01 2000 01:00:00 GMT-0800 (PST), -// Sat Jan 01 2000 01:15:00 GMT-0800 (PST), -// Sat Jan 01 2000 01:30:00 GMT-0800 (PST), -// Sat Jan 01 2000 01:45:00 GMT-0800 (PST), -// Sat Jan 01 2000 02:00:00 GMT-0800 (PST)] -``` - -Alternatively, pass a test function to [*interval*.filter](https://github.com/d3/d3-time#interval_filter): - -```js -x.ticks(d3.timeMinute.filter(function(d) { - return d.getMinutes() % 15 === 0; -})); -``` - -Note: in some cases, such as with day ticks, specifying a *step* can result in irregular spacing of ticks because time intervals have varying length. - -# time.tickFormat([count[, specifier]]) [<>](https://github.com/d3/d3-scale/blob/master/src/time.js "Source") -
# time.tickFormat([interval[, specifier]]) - -Returns a time format function suitable for displaying [tick](#time_ticks) values. The specified *count* or *interval* is currently ignored, but is accepted for consistency with other scales such as [*continuous*.tickFormat](#continuous_tickFormat). If a format *specifier* is specified, this method is equivalent to [format](https://github.com/d3/d3-time-format#format). If *specifier* is not specified, the default time format is returned. The default multi-scale time format chooses a human-readable representation based on the specified date as follows: - -* `%Y` - for year boundaries, such as `2011`. -* `%B` - for month boundaries, such as `February`. -* `%b %d` - for week boundaries, such as `Feb 06`. -* `%a %d` - for day boundaries, such as `Mon 07`. -* `%I %p` - for hour boundaries, such as `01 AM`. -* `%I:%M` - for minute boundaries, such as `01:23`. -* `:%S` - for second boundaries, such as `:45`. -* `.%L` - milliseconds for all other times, such as `.012`. - -Although somewhat unusual, this default behavior has the benefit of providing both local and global context: for example, formatting a sequence of ticks as [11 PM, Mon 07, 01 AM] reveals information about hours, dates, and day simultaneously, rather than just the hours [11 PM, 12 AM, 01 AM]. See [d3-time-format](https://github.com/d3/d3-time-format) if you’d like to roll your own conditional time format. - -# time.nice([count]) [<>](https://github.com/d3/d3-scale/blob/master/src/time.js "Source") -
# time.nice([interval[, step]]) - -Extends the [domain](#time_domain) so that it starts and ends on nice round values. This method typically modifies the scale’s domain, and may only extend the bounds to the nearest round value. See [*continuous*.nice](#continuous_nice) for more. - -An optional tick *count* argument allows greater control over the step size used to extend the bounds, guaranteeing that the returned [ticks](#time_ticks) will exactly cover the domain. Alternatively, a [time *interval*](https://github.com/d3/d3-time#intervals) may be specified to explicitly set the ticks. If an *interval* is specified, an optional *step* may also be specified to skip some ticks. For example, `time.nice(d3.timeSecond, 10)` will extend the domain to an even ten seconds (0, 10, 20, etc.). See [*time*.ticks](#time_ticks) and [*interval*.every](https://github.com/d3/d3-time#interval_every) for further detail. - -Nicing is useful if the domain is computed from data, say using [extent](https://github.com/d3/d3-array#extent), and may be irregular. For example, for a domain of [2009-07-13T00:02, 2009-07-13T23:48], the nice domain is [2009-07-13, 2009-07-14]. If the domain has more than two values, nicing the domain only affects the first and last value. - -# d3.scaleUtc([[domain, ]range]) [<>](https://github.com/d3/d3-scale/blob/master/src/utcTime.js "Source") - -Equivalent to [time](#time), but the returned time scale operates in [Coordinated Universal Time](https://en.wikipedia.org/wiki/Coordinated_Universal_Time) rather than local time. - -### Sequential Scales - -Sequential scales, like [diverging scales](#diverging-scales), are similar to [continuous scales](#continuous-scales) in that they map a continuous, numeric input domain to a continuous output range. However, unlike continuous scales, the output range of a sequential scale is fixed by its interpolator and not configurable. These scales do not expose [invert](#continuous_invert), [range](#continuous_range), [rangeRound](#continuous_rangeRound) and [interpolate](#continuous_interpolate) methods. - -# d3.scaleSequential([[domain, ]interpolator]) [<>](https://github.com/d3/d3-scale/blob/master/src/sequential.js "Source") - -Constructs a new sequential scale with the specified [*domain*](#sequential_domain) and [*interpolator*](#sequential_interpolator) function. If *domain* is not specified, it defaults to [0, 1]. If *interpolator* is not specified, it defaults to the identity function. When the scale is [applied](#_sequential), the interpolator will be invoked with a value typically in the range [0, 1], where 0 represents the minimum value and 1 represents the maximum value. For example, to implement the ill-advised [HSL](https://github.com/d3/d3-color#hsl) rainbow scale: - -```js -var rainbow = d3.scaleSequential(function(t) { - return d3.hsl(t * 360, 1, 0.5) + ""; -}); -``` - -A more aesthetically-pleasing and perceptually-effective cyclical hue encoding is to use [d3.interpolateRainbow](https://github.com/d3/d3-scale-chromatic/blob/master/README.md#interpolateRainbow): - -```js -var rainbow = d3.scaleSequential(d3.interpolateRainbow); -``` - -# sequential(value) [<>](https://github.com/d3/d3-scale/blob/master/src/sequential.js "Source") - -See [*continuous*](#_continuous). - -# sequential.domain([domain]) [<>](https://github.com/d3/d3-scale/blob/master/src/sequential.js "Source") - -See [*continuous*.domain](#continuous_domain).

However, unlike continuous scales, the output range of a diverging scale is fixed by its interpolator and not configurable. These scales do not expose [invert](#continuous_invert), [range](#continuous_range), [rangeRound](#continuous_rangeRound) and [interpolate](#continuous_interpolate) methods. - -# d3.scaleDiverging([[domain, ]interpolator]) [<>](https://github.com/d3/d3-scale/blob/master/src/diverging.js "Source") - -Constructs a new diverging scale with the specified [*domain*](#diverging_domain) and [*interpolator*](#diverging_interpolator) function. If *domain* is not specified, it defaults to [0, 1]. If *interpolator* is not specified, it defaults to the identity function. When the scale is [applied](#_diverging), the interpolator will be invoked with a value typically in the range [0, 1], where 0 represents the extreme negative value, 0.5 represents the neutral value, and 1 represents the extreme positive value.

The continuous input domain is divided into uniform segments based on the number of values in (*i.e.*, the cardinality of) the output range. Each range value *y* can be expressed as a quantized linear function of the domain value *x*: *y* = *m round(x)* + *b*. See [bl.ocks.org/4060606](http://bl.ocks.org/mbostock/4060606) for an example. - -# d3.scaleQuantize([[domain, ]range]) [<>](https://github.com/d3/d3-scale/blob/master/src/quantize.js "Source") - -Constructs a new quantize scale with the specified [*domain*](#quantize_domain) and [*range*](#quantize_range).

The domain is considered continuous and thus the scale will accept any reasonable input value; however, the domain is specified as a discrete set of sample values. The number of values in (the cardinality of) the output range determines the number of quantiles that will be computed from the domain. To compute the quantiles, the domain is sorted, and treated as a [population of discrete values](https://en.wikipedia.org/wiki/Quantile#Quantiles_of_a_population); see d3-array’s [quantile](https://github.com/d3/d3-array#quantile). See [bl.ocks.org/8ca036b3505121279daf](http://bl.ocks.org/mbostock/8ca036b3505121279daf) for an example. - -# d3.scaleQuantile([[domain, ]range]) [<>](https://github.com/d3/d3-scale/blob/master/src/quantile.js "Source") - -Constructs a new quantile scale with the specified [*domain*](#quantile_domain) and [*range*](#quantile_range). If either *domain* or *range* is not specified, each defaults to the empty array. The quantile scale is invalid until both a domain and range are specified. - -# quantile(value) [<>](https://github.com/d3/d3-scale/blob/master/src/quantile.js "Source") - -Given a *value* in the input [domain](#quantile_domain), returns the corresponding value in the output [range](#quantile_range). - -# quantile.invertExtent(value) [<>](https://github.com/d3/d3-scale/blob/master/src/quantile.js "Source") - -Returns the extent of values in the [domain](#quantile_domain) [x0, x1] for the corresponding *value* in the [range](#quantile_range): the inverse of [*quantile*](#_quantile). This method is useful for interaction, say to determine the value in the domain that corresponds to the pixel location under the mouse. - -# quantile.domain([domain]) [<>](https://github.com/d3/d3-scale/blob/master/src/quantile.js "Source") - -If *domain* is specified, sets the domain of the quantile scale to the specified set of discrete numeric values. The array must not be empty, and must contain at least one numeric value; NaN, null and undefined values are ignored and not considered part of the sample population. If the elements in the given array are not numbers, they will be coerced to numbers. A copy of the input array is sorted and stored internally. If *domain* is not specified, returns the scale’s current domain. - -# quantile.range([range]) [<>](https://github.com/d3/d3-scale/blob/master/src/quantile.js "Source") - -If *range* is specified, sets the discrete values in the range. The array must not be empty, and may contain any type of value. The number of values in (the cardinality, or length, of) the *range* array determines the number of quantiles that are computed. For example, to compute quartiles, *range* must be an array of four elements such as [0, 1, 2, 3]. If *range* is not specified, returns the current range. - -# quantile.quantiles() [<>](https://github.com/d3/d3-scale/blob/master/src/quantile.js "Source") - -Returns the quantile thresholds. If the [range](#quantile_range) contains *n* discrete values, the returned array will contain *n* - 1 thresholds. Values less than the first threshold are considered in the first quantile; values greater than or equal to the first threshold but less than the second threshold are in the second quantile, and so on. Internally, the thresholds array is used with [bisect](https://github.com/d3/d3-array#bisect) to find the output quantile associated with the given input value. - -# quantile.copy() [<>](https://github.com/d3/d3-scale/blob/master/src/quantile.js "Source") - -Returns an exact copy of this scale. Changes to this scale will not affect the returned scale, and vice versa. - -### Threshold Scales - -Threshold scales are similar to [quantize scales](#quantize-scales), except they allow you to map arbitrary subsets of the domain to discrete values in the range. The input domain is still continuous, and divided into slices based on a set of threshold values. See [bl.ocks.org/3306362](http://bl.ocks.org/mbostock/3306362) for an example. - -# d3.scaleThreshold([[domain, ]range]) [<>](https://github.com/d3/d3-scale/blob/master/src/threshold.js "Source") - -Constructs a new threshold scale with the specified [*domain*](#threshold_domain) and [*range*](#threshold_range). It *domain* is not specified, it defaulst to [0.5]. If *range* is not specified, it defaults to [0, 1]. Thus, the default threshold scale is equivalent to the [Math.round](https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Math/round) function for numbers; for example threshold(0.49) returns 0, and threshold(0.51) returns 1. - -# threshold(value) [<>](https://github.com/d3/d3-scale/blob/master/src/threshold.js "Source") - -Given a *value* in the input [domain](#threshold_domain), returns the corresponding value in the output [range](#threshold_range). For example: - -```js -var color = d3.scaleThreshold() - .domain([0, 1]) - .range(["red", "white", "green"]); - -color(-1); // "red" -color(0); // "white" -color(0.5); // "white" -color(1); // "green" -color(1000); // "green" -``` - -# threshold.invertExtent(value) [<>](https://github.com/d3/d3-scale/blob/master/src/threshold.js "Source") - -Returns the extent of values in the [domain](#threshold_domain) [x0, x1] for the corresponding *value* in the [range](#threshold_range), representing the inverse mapping from range to domain. This method is useful for interaction, say to determine the value in the domain that corresponds to the pixel location under the mouse. For example: - -```js -var color = d3.scaleThreshold() - .domain([0, 1]) - .range(["red", "white", "green"]); - -color.invertExtent("red"); // [undefined, 0] -color.invertExtent("white"); // [0, 1] -color.invertExtent("green"); // [1, undefined] -``` - -# threshold.domain([domain]) [<>](https://github.com/d3/d3-scale/blob/master/src/threshold.js "Source") - -If *domain* is specified, sets the scale’s domain to the specified array of values. The values must be in ascending order or the behavior of the scale is undefined. The values are typically numbers, but any naturally ordered values (such as strings) will work; a threshold scale can be used to encode any type that is ordered. If the number of values in the scale’s range is N+1, the number of values in the scale’s domain must be N. If there are fewer than N elements in the domain, the additional values in the range are ignored. If there are more than N elements in the domain, the scale may return undefined for some inputs. If *domain* is not specified, returns the scale’s current domain. - -# threshold.range([range]) [<>](https://github.com/d3/d3-scale/blob/master/src/threshold.js "Source") - -If *range* is specified, sets the scale’s range to the specified array of values. If the number of values in the scale’s domain is N, the number of values in the scale’s range must be N+1. If there are fewer than N+1 elements in the range, the scale may return undefined for some inputs. If there are more than N+1 elements in the range, the additional values are ignored. The elements in the given array need not be numbers; any value or type will work. If *range* is not specified, returns the scale’s current range. - -# threshold.copy() [<>](https://github.com/d3/d3-scale/blob/master/src/threshold.js "Source") - -Returns an exact copy of this scale. Changes to this scale will not affect the returned scale, and vice versa. - -### Ordinal Scales - -Unlike [continuous scales](#continuous-scales), ordinal scales have a discrete domain and range. For example, an ordinal scale might map a set of named categories to a set of colors, or determine the horizontal positions of columns in a column chart. - -# d3.scaleOrdinal([[domain, ]range]) [<>](https://github.com/d3/d3-scale/blob/master/src/ordinal.js "Source") - -Constructs a new ordinal scale with the specified [*domain*](#ordinal_domain) and [*range*](#ordinal_range). If *domain* is not specified, it defaults to the empty array. If *range* is not specified, it defaults to the empty array; an ordinal scale always returns undefined until a non-empty range is defined. - -# ordinal(value) [<>](https://github.com/d3/d3-scale/blob/master/src/ordinal.js "Source") - -Given a *value* in the input [domain](#ordinal_domain), returns the corresponding value in the output [range](#ordinal_range). If the given *value* is not in the scale’s [domain](#ordinal_domain), returns the [unknown](#ordinal_unknown); or, if the unknown value is [implicit](#scaleImplicit) (the default), then the *value* is implicitly added to the domain and the next-available value in the range is assigned to *value*, such that this and subsequent invocations of the scale given the same input *value* return the same output value. - -# ordinal.domain([domain]) [<>](https://github.com/d3/d3-scale/blob/master/src/ordinal.js "Source") - -If *domain* is specified, sets the domain to the specified array of values. The first element in *domain* will be mapped to the first element in the range, the second domain value to the second range value, and so on. Domain values are stored internally in a map from stringified value to index; the resulting index is then used to retrieve a value from the range. Thus, an ordinal scale’s values must be coercible to a string, and the stringified version of the domain value uniquely identifies the corresponding range value. If *domain* is not specified, this method returns the current domain. - -Setting the domain on an ordinal scale is optional if the [unknown value](#ordinal_unknown) is [implicit](#scaleImplicit) (the default). In this case, the domain will be inferred implicitly from usage by assigning each unique value passed to the scale a new value from the range. Note that an explicit domain is recommended to ensure deterministic behavior, as inferring the domain from usage will be dependent on ordering. - -# ordinal.range([range]) [<>](https://github.com/d3/d3-scale/blob/master/src/ordinal.js "Source") - -If *range* is specified, sets the range of the ordinal scale to the specified array of values. The first element in the domain will be mapped to the first element in *range*, the second domain value to the second range value, and so on. If there are fewer elements in the range than in the domain, the scale will reuse values from the start of the range. If *range* is not specified, this method returns the current range. - -# ordinal.unknown([value]) [<>](https://github.com/d3/d3-scale/blob/master/src/ordinal.js "Source") - -If *value* is specified, sets the output value of the scale for unknown input values and returns this scale. If *value* is not specified, returns the current unknown value, which defaults to [implicit](#implicit). The implicit value enables implicit domain construction; see [*ordinal*.domain](#ordinal_domain). - -# ordinal.copy() [<>](https://github.com/d3/d3-scale/blob/master/src/ordinal.js "Source") - -Returns an exact copy of this ordinal scale. Changes to this scale will not affect the returned scale, and vice versa. - -# d3.scaleImplicit [<>](https://github.com/d3/d3-scale/blob/master/src/ordinal.js "Source") - -A special value for [*ordinal*.unknown](#ordinal_unknown) that enables implicit domain construction: unknown values are implicitly added to the domain. - -#### Band Scales - -Band scales are like [ordinal scales](#ordinal-scales) except the output range is continuous and numeric. Discrete output values are automatically computed by the scale by dividing the continuous range into uniform bands. Band scales are typically used for bar charts with an ordinal or categorical dimension. The [unknown value](#ordinal_unknown) of a band scale is effectively undefined: they do not allow implicit domain construction. - -band - -# d3.scaleBand([[domain, ]range]) [<>](https://github.com/d3/d3-scale/blob/master/src/band.js "Source") - -Constructs a new band scale with the specified [*domain*](#band_domain) and [*range*](#band_range), no [padding](#band_padding), no [rounding](#band_round) and center [alignment](#band_align). If *domain* is not specified, it defaults to the empty domain. If *range* is not specified, it defaults to the unit range [0, 1]. - -# band(*value*) [<>](https://github.com/d3/d3-scale/blob/master/src/band.js "Source") - -Given a *value* in the input [domain](#band_domain), returns the start of the corresponding band derived from the output [range](#band_range). If the given *value* is not in the scale’s domain, returns undefined. - -# band.domain([domain]) [<>](https://github.com/d3/d3-scale/blob/master/src/band.js "Source") - -If *domain* is specified, sets the domain to the specified array of values. The first element in *domain* will be mapped to the first band, the second domain value to the second band, and so on. Domain values are stored internally in a map from stringified value to index; the resulting index is then used to determine the band. Thus, a band scale’s values must be coercible to a string, and the stringified version of the domain value uniquely identifies the corresponding band. If *domain* is not specified, this method returns the current domain. - -# band.range([range]) [<>](https://github.com/d3/d3-scale/blob/master/src/band.js "Source") - -If *range* is specified, sets the scale’s range to the specified two-element array of numbers. If the elements in the given array are not numbers, they will be coerced to numbers. If *range* is not specified, returns the scale’s current range, which defaults to [0, 1]. - -# band.rangeRound([range]) [<>](https://github.com/d3/d3-scale/blob/master/src/band.js "Source") - -Sets the scale’s [*range*](#band_range) to the specified two-element array of numbers while also enabling [rounding](#band_round). This is a convenience method equivalent to: - -```js -band - .range(range) - .round(true); -``` - -Rounding is sometimes useful for avoiding antialiasing artifacts, though also consider the [shape-rendering](https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/shape-rendering) “crispEdges” styles. - -# band.round([round]) [<>](https://github.com/d3/d3-scale/blob/master/src/band.js "Source") - -If *round* is specified, enables or disables rounding accordingly.

Rounding is sometimes useful for avoiding antialiasing artifacts, though also consider the [shape-rendering](https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/shape-rendering) “crispEdges” styles. Note that if the width of the domain is not a multiple of the cardinality of the range, there may be leftover unused space, even without padding! Use [*band*.align](#band_align) to specify how the leftover space is distributed. - -# band.paddingInner([padding]) [<>](https://github.com/d3/d3-scale/blob/master/src/band.js "Source") - -If *padding* is specified, sets the inner padding to the specified number which must be less than or equal to 1. If *padding* is not specified, returns the current inner padding which defaults to 0. The inner padding specifies the proportion of the range that is reserved for blank space between bands; a value of 0 means no blank space between bands, and a value of 1 means a [bandwidth](#band_bandwidth) of zero. - -# band.paddingOuter([padding]) [<>](https://github.com/d3/d3-scale/blob/master/src/band.js "Source") - -If *padding* is specified, sets the outer padding to the specified number which is typically in the range [0, 1]. If *padding* is not specified, returns the current outer padding which defaults to 0. The outer padding specifies the amount of blank space, in terms of multiples of the [step](#band_step), to reserve before the first band and after the last band. - -# band.padding([padding]) [<>](https://github.com/d3/d3-scale/blob/master/src/band.js "Source") - -A convenience method for setting the [inner](#band_paddingInner) and [outer](#band_paddingOuter) padding to the same *padding* value.

If *align* is not specified, returns the current alignment which defaults to 0.5. The alignment specifies how any leftover unused space in the range is distributed. A value of 0.5 indicates that the leftover space should be equally distributed before the first band and after the last band; *i.e.*, the bands should be centered within the range. A value of 0 or 1 may be used to shift the bands to one side, say to position them adjacent to an axis. - -# band.bandwidth() [<>](https://github.com/d3/d3-scale/blob/master/src/band.js "Source") - -Returns the width of each band. - -# band.step() [<>](https://github.com/d3/d3-scale/blob/master/src/band.js "Source") - -Returns the distance between the starts of adjacent bands. - -# band.copy() [<>](https://github.com/d3/d3-scale/blob/master/src/band.js "Source") - -Returns an exact copy of this scale. Changes to this scale will not affect the returned scale, and vice versa. - -#### Point Scales - -Point scales are a variant of [band scales](#band-scales) with the bandwidth fixed to zero. Point scales are typically used for scatterplots with an ordinal or categorical dimension. The [unknown value](#ordinal_unknown) of a point scale is always undefined: they do not allow implicit domain construction. - -point - -# d3.scalePoint([[domain, ]range]) [<>](https://github.com/d3/d3-scale/blob/master/src/band.js "Source") - -Constructs a new point scale with the specified [*domain*](#point_domain) and [*range*](#point_range), no [padding](#point_padding), no [rounding](#point_round) and center [alignment](#point_align).

Using the [data join](#joining-data)’s [enter](#selection_enter) and [exit](#selection_enter) selections, you can also [add](#selection_append) or [remove](#selection_remove) elements to correspond to data. - -Selection methods typically return the current selection, or a new selection, allowing the concise application of multiple operations on a given selection via method chaining. For example, to set the class and color style of all paragraph elements in the current document: - -```js -d3.selectAll("p") - .attr("class", "graf") - .style("color", "red"); -``` - -This is equivalent to: - -```js -const p = d3.selectAll("p"); -p.attr("class", "graf"); -p.style("color", "red"); -``` - -By convention, selection methods that return the current selection use *four* spaces of indent, while methods that return a new selection use only *two*. This helps reveal changes of context by making them stick out of the chain: - -```js -d3.select("body") - .append("svg") - .attr("width", 960) - .attr("height", 500) - .append("g") - .attr("transform", "translate(20,20)") - .append("rect") - .attr("width", 920) - .attr("height", 460); -``` - -Selections are immutable. All selection methods that affect which elements are selected (or their order) return a new selection rather than modifying the current selection. However, note that elements are necessarily mutable, as selections drive transformations of the document! - -## Installing - -If you use NPM, `npm install d3-selection`. Otherwise, download the [latest release](https://github.com/d3/d3-selection/releases/latest). You can also load directly from [d3js.org](https://d3js.org), either as a [standalone library](https://d3js.org/d3-selection.v1.min.js) or as part of [D3](https://github.com/d3/d3). AMD, CommonJS, and vanilla environments are supported.

Selection methods come in two forms: select and selectAll: the former selects only the first matching element, while the latter selects all matching elements in document order. The top-level selection methods, [d3.select](#select) and [d3.selectAll](#selectAll), query the entire document; the subselection methods, [*selection*.select](#selection_select) and [*selection*.selectAll](#selection_selectAll), restrict selection to descendants of the selected elements. - -# d3.selection() [<>](https://github.com/d3/d3-selection/blob/master/src/selection/index.js#L38 "Source") - -[Selects](#select) the root element, `document.documentElement`. This function can also be used to test for selections (`instanceof d3.selection`) or to extend the selection prototype. For example, to add a method to check checkboxes: - -```js -d3.selection.prototype.checked = function(value) { - return arguments.length < 1 - ? this.property("checked") - : this.property("checked", !!value); -}; -``` - -And then to use: - -```js -d3.selectAll("input[type=checkbox]").checked(true); -``` - -# d3.select(selector) [<>](https://github.com/d3/d3-selection/blob/master/src/select.js#L3 "Source") - -Selects the first element that matches the specified *selector* string. If no elements match the *selector*, returns an empty selection. If multiple elements match the *selector*, only the first matching element (in document order) will be selected. For example, to select the first anchor element: - -```js -const anchor = d3.select("a"); -``` - -If the *selector* is not a string, instead selects the specified node; this is useful if you already have a reference to a node, such as `this` within an event listener or a global such as `document.body`. For example, to make a clicked paragraph red: - -```js -d3.selectAll("p").on("click", function() { - d3.select(this).style("color", "red"); -}); -``` - -# d3.selectAll(selector) [<>](https://github.com/d3/d3-selection/blob/master/src/selectAll.js#L3 "Source") - -Selects all elements that match the specified *selector* string. The elements will be selected in document order (top-to-bottom). If no elements in the document match the *selector*, or if the *selector* is null or undefined, returns an empty selection. For example, to select all paragraphs: - -```js -const paragraph = d3.selectAll("p"); -``` - -If the *selector* is not a string, instead selects the specified array of nodes; this is useful if you already have a reference to nodes, such as `this.childNodes` within an event listener or a global such as `document.links`. The nodes may instead be a pseudo-array such as a `NodeList` or `arguments`. For example, to color all links red: - -```js -d3.selectAll(document.links).style("color", "red"); -``` - -# selection.select(selector) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/select.js "Source") - -For each selected element, selects the first descendant element that matches the specified *selector* string. If no element matches the specified selector for the current element, the element at the current index will be null in the returned selection. (If the *selector* is null, every element in the returned selection will be null, resulting in an empty selection.) If the current element has associated data, this data is propagated to the corresponding selected element. If multiple elements match the selector, only the first matching element in document order is selected. For example, to select the first bold element in every paragraph: - -```js -const b = d3.selectAll("p").select("b"); -``` - -If the *selector* is a function, it is evaluated for each selected element, in order, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]). It must return an element, or null if there is no matching element. For example, to select the previous sibling of each paragraph: - -```js -const previous = d3.selectAll("p").select(function() { - return this.previousElementSibling; -}); -``` - -Unlike [*selection*.selectAll](#selection_selectAll), *selection*.select does not affect grouping: it preserves the existing group structure and indexes, and propagates data (if any) to selected children. Grouping plays an important role in the [data join](#joining-data). See [Nested Selections](http://bost.ocks.org/mike/nest/) and [How Selections Work](http://bost.ocks.org/mike/selection/) for more on this topic. - -# selection.selectAll(selector) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/selectAll.js "Source") - -For each selected element, selects the descendant elements that match the specified *selector* string. The elements in the returned selection are grouped by their corresponding parent node in this selection. If no element matches the specified selector for the current element, or if the *selector* is null, the group at the current index will be empty. The selected elements do not inherit data from this selection; use [*selection*.data](#selection_data) to propagate data to children. For example, to select the bold elements in every paragraph: - -```js -const b = d3.selectAll("p").selectAll("b"); -``` - -If the *selector* is a function, it is evaluated for each selected element, in order, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]). It must return an array of elements (or a pseudo-array, such as a NodeList), or the empty array if there are no matching elements. For example, to select the previous and next siblings of each paragraph: - -```js -const sibling = d3.selectAll("p").selectAll(function() { - return [ - this.previousElementSibling, - this.nextElementSibling - ]; -}); -``` - -Unlike [*selection*.select](#selection_select), *selection*.selectAll does affect grouping: each selected descendant is grouped by the parent element in the originating selection. Grouping plays an important role in the [data join](#joining-data). See [Nested Selections](http://bost.ocks.org/mike/nest/) and [How Selections Work](http://bost.ocks.org/mike/selection/) for more on this topic. - -# selection.filter(filter) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/filter.js "Source") - -Filters the selection, returning a new selection that contains only the elements for which the specified *filter* is true. The *filter* may be specified either as a selector string or a function. If the *filter* is a function, it is evaluated for each selected element, in order, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]). - -For example, to filter a selection of table rows to contain only even rows: - -```js -const even = d3.selectAll("tr").filter(":nth-child(even)"); -``` - -This is approximately equivalent to using [d3.selectAll](#selectAll) directly, although the indexes may be different: - -```js -const even = d3.selectAll("tr:nth-child(even)"); -``` - -Similarly, using a function: - -```js -const even = d3.selectAll("tr").filter((d, i) => i & 1); -``` - -Or using [*selection*.select](#selection_select) (and avoiding an arrow function, since *this* is needed to refer to the current element): - -```js -const even = d3.selectAll("tr").select(function(d, i) { return i & 1 ? this : null; }); -``` - -Note that the `:nth-child` pseudo-class is a one-based index rather than a zero-based index. Also, the above filter functions do not have precisely the same meaning as `:nth-child`; they rely on the selection index rather than the number of preceding sibling elements in the DOM. - -The returned filtered selection preserves the parents of this selection, but like [*array*.filter](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter), it does not preserve indexes as some elements may be removed; use [*selection*.select](#selection_select) to preserve the index, if needed. - -# selection.merge(other) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/merge.js "Source") - -Returns a new selection merging this selection with the specified *other* selection. The returned selection has the same number of groups and the same parents as this selection. Any missing (null) elements in this selection are filled with the corresponding element, if present (not null), from the specified *selection*. (If the *other* selection has additional groups or parents, they are ignored.) - -This method is used internally by [*selection*.join](#selection_join) to merge the [enter](#selection_enter) and [update](#selection_data) selections after [binding data](#joining-data). You can also merge explicitly, although note that since merging is based on element index, you should use operations that preserve index, such as [*selection*.select](#selection_select) instead of [*selection*.filter](#selection_filter). For example: - -```js -const odd = selection.select(function(d, i) { return i & 1 ? this : null; )); -const even = selection.select(function(d, i) { return i & 1 ? null : this; )); -const merged = odd.merge(even); -``` - -See [*selection*.data](#selection_data) for more. - -This method is not intended for concatenating arbitrary selections, however: if both this selection and the specified *other* selection have (non-null) elements at the same index, this selection’s element is returned in the merge and the *other* selection’s element is ignored. - -# d3.matcher(selector) [<>](https://github.com/d3/d3-selection/blob/master/src/matcher.js "Source") - -Given the specified *selector*, returns a function which returns true if `this` element [matches](https://developer.mozilla.org/en-US/docs/Web/API/Element/matches) the specified selector. This method is used internally by [*selection*.filter](#selection_filter). For example, this: - -```js -const div = selection.filter("div"); -``` - -Is equivalent to: - -```js -const div = selection.filter(d3.matcher("div")); -``` - -(Although D3 is not a compatibility layer, this implementation does support vendor-prefixed implementations due to the recent standardization of *element*.matches.) - -# d3.selector(selector) [<>](https://github.com/d3/d3-selection/blob/master/src/selector.js "Source") - -Given the specified *selector*, returns a function which returns the first descendant of `this` element that matches the specified selector. This method is used internally by [*selection*.select](#selection_select). For example, this: - -```js -const div = selection.select("div"); -``` - -Is equivalent to: - -```js -const div = selection.select(d3.selector("div")); -``` - -# d3.selectorAll(selector) [<>](https://github.com/d3/d3-selection/blob/master/src/selectAll.js "Source") - -Given the specified *selector*, returns a function which returns all descendants of `this` element that match the specified selector. This method is used internally by [*selection*.selectAll](#selection_selectAll). For example, this: - -```js -const div = selection.selectAll("div"); -``` - -Is equivalent to: - -```js -const div = selection.selectAll(d3.selectorAll("div")); -``` - -# d3.window(node) [<>](https://github.com/d3/d3-selection/blob/master/src/window.js "Source") - -Returns the owner window for the specified *node*. If *node* is a node, returns the owner document’s default view; if *node* is a document, returns its default view; otherwise returns the *node*. - -# d3.style(node, name) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/style.js#L32 "Source") - -Returns the value of the style property with the specified *name* for the specified *node*. If the *node* has an inline style with the specified *name*, its value is returned; otherwise, the [computed property value](https://developer.mozilla.org/en-US/docs/Web/CSS/computed_value) is returned. See also [*selection*.style](#selection_style). - -### Modifying Elements - -After selecting elements, use the selection’s transformation methods to affect document content. For example, to set the name attribute and color style of an anchor element: - -```js -d3.select("a") - .attr("name", "fred") - .style("color", "red"); -``` - -To experiment with selections, visit [d3js.org](https://d3js.org) and open your browser’s developer console! (In Chrome, open the console with ⌥⌘J.) Select elements and then inspect the returned selection to see which elements are selected and how they are grouped. Call selection methods and see how the page content changes. - -# selection.attr(name[, value]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/attr.js "Source") - -If a *value* is specified, sets the attribute with the specified *name* to the specified value on the selected elements and returns this selection. If the *value* is a constant, all elements are given the same attribute value; otherwise, if the *value* is a function, it is evaluated for each selected element, in order, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]). The function’s return value is then used to set each element’s attribute. A null value will remove the specified attribute. - -If a *value* is not specified, returns the current value of the specified attribute for the first (non-null) element in the selection. This is generally useful only if you know that the selection contains exactly one element. - -The specified *name* may have a namespace prefix, such as `xlink:href` to specify the `href` attribute in the XLink namespace. See [namespaces](#namespaces) for the map of supported namespaces; additional namespaces can be registered by adding to the map. - -# selection.classed(names[, value]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/classed.js "Source") - -If a *value* is specified, assigns or unassigns the specified CSS class *names* on the selected elements by setting the `class` attribute or modifying the `classList` property and returns this selection. The specified *names* is a string of space-separated class names. For example, to assign the classes `foo` and `bar` to the selected elements: - -```js -selection.classed("foo bar", true); -``` - -If the *value* is truthy, then all elements are assigned the specified classes; otherwise, the classes are unassigned. If the *value* is a function, it is evaluated for each selected element, in order, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]). The function’s return value is then used to assign or unassign classes on each element. For example, to randomly associate the class *foo* with on average half the selected elements: - -```js -selection.classed("foo", () => Math.random() > 0.5); -``` - -If a *value* is not specified, returns true if and only if the first (non-null) selected element has the specified *classes*. This is generally useful only if you know the selection contains exactly one element. - -# selection.style(name[, value[, priority]]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/style.js "Source") - -If a *value* is specified, sets the style property with the specified *name* to the specified value on the selected elements and returns this selection. If the *value* is a constant, then all elements are given the same style property value; otherwise, if the *value* is a function, it is evaluated for each selected element, in order, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]). The function’s return value is then used to set each element’s style property. A null value will remove the style property. An optional *priority* may also be specified, either as null or the string `important` (without the exclamation point). - -If a *value* is not specified, returns the current value of the specified style property for the first (non-null) element in the selection. The current value is defined as the element’s inline value, if present, and otherwise its [computed value](https://developer.mozilla.org/en-US/docs/Web/CSS/computed_value). Accessing the current style value is generally useful only if you know the selection contains exactly one element. - -Caution: unlike many SVG attributes, CSS styles typically have associated units. For example, `3px` is a valid stroke-width property value, while `3` is not. Some browsers implicitly assign the `px` (pixel) unit to numeric values, but not all browsers do: IE, for example, throws an “invalid arguments” error! - -# selection.property(name[, value]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/property.js "Source") - -Some HTML elements have special properties that are not addressable using attributes or styles, such as a form field’s text `value` and a checkbox’s `checked` boolean. Use this method to get or set these properties. - -If a *value* is specified, sets the property with the specified *name* to the specified value on selected elements. If the *value* is a constant, then all elements are given the same property value; otherwise, if the *value* is a function, it is evaluated for each selected element, in order, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]). The function’s return value is then used to set each element’s property. A null value will delete the specified property. - -If a *value* is not specified, returns the value of the specified property for the first (non-null) element in the selection. This is generally useful only if you know the selection contains exactly one element. - -# selection.text([value]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/text.js "Source") - -If a *value* is specified, sets the [text content](http://www.w3.org/TR/DOM-Level-3-Core/core.html#Node3-textContent) to the specified value on all selected elements, replacing any existing child elements. If the *value* is a constant, then all elements are given the same text content; otherwise, if the *value* is a function, it is evaluated for each selected element, in order, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]). The function’s return value is then used to set each element’s text content. A null value will clear the content. - -If a *value* is not specified, returns the text content for the first (non-null) element in the selection. This is generally useful only if you know the selection contains exactly one element. - -# selection.html([value]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/html.js "Source") - -If a *value* is specified, sets the [inner HTML](http://dev.w3.org/html5/spec-LC/apis-in-html-documents.html#innerhtml) to the specified value on all selected elements, replacing any existing child elements. If the *value* is a constant, then all elements are given the same inner HTML; otherwise, if the *value* is a function, it is evaluated for each selected element, in order, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]). The function’s return value is then used to set each element’s inner HTML. A null value will clear the content. - -If a *value* is not specified, returns the inner HTML for the first (non-null) element in the selection. This is generally useful only if you know the selection contains exactly one element. - -Use [*selection*.append](#selection_append) or [*selection*.insert](#selection_insert) instead to create data-driven content; this method is intended for when you want a little bit of HTML, say for rich formatting. Also, *selection*.html is only supported on HTML elements. SVG elements and other non-HTML elements do not support the innerHTML property, and thus are incompatible with *selection*.html. Consider using [XMLSerializer](https://developer.mozilla.org/en-US/docs/XMLSerializer) to convert a DOM subtree to text. See also the [innersvg polyfill](https://code.google.com/p/innersvg/), which provides a shim to support the innerHTML property on SVG elements. - -# selection.append(type) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/append.js "Source") - -If the specified *type* is a string, appends a new element of this type (tag name) as the last child of each selected element, or before the next following sibling in the update selection if this is an [enter selection](#selection_enter). The latter behavior for enter selections allows you to insert elements into the DOM in an order consistent with the new bound data; however, note that [*selection*.order](#selection_order) may still be required if updating elements change order (*i.e.*, if the order of new data is inconsistent with old data). - -If the specified *type* is a function, it is evaluated for each selected element, in order, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]). This function should return an element to be appended. (The function typically creates a new element, but it may instead return an existing element.) For example, to append a DIV element to each paragraph: - -```js -d3.selectAll("p").append("div"); -``` - -This is equivalent to: - -```js -d3.selectAll("p").append(() => document.createElement("div")); -``` - -Which is equivalent to: - -```js -d3.selectAll("p").select(function() { - return this.appendChild(document.createElement("div")); -}); -``` - -In both cases, this method returns a new selection containing the appended elements. Each new element inherits the data of the current elements, if any, in the same manner as [*selection*.select](#selection_select). - -The specified *name* may have a namespace prefix, such as `svg:text` to specify a `text` attribute in the SVG namespace. See [namespaces](#namespaces) for the map of supported namespaces; additional namespaces can be registered by adding to the map. If no namespace is specified, the namespace will be inherited from the parent element; or, if the name is one of the known prefixes, the corresponding namespace will be used (for example, `svg` implies `svg:svg`). - -# selection.insert(type[, before]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/insert.js "Source") - -If the specified *type* is a string, inserts a new element of this type (tag name) before the first element matching the specified *before* selector for each selected element. For example, a *before* selector `:first-child` will prepend nodes before the first child. If *before* is not specified, it defaults to null. (To append elements in an order consistent with [bound data](#joining-data), use [*selection*.append](#selection_append).) - -Both *type* and *before* may instead be specified as functions which are evaluated for each selected element, in order, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]). The *type* function should return an element to be inserted; the *before* function should return the child element before which the element should be inserted. For example, to append a DIV element to each paragraph: - -```js -d3.selectAll("p").insert("div"); -``` - -This is equivalent to: - -```js -d3.selectAll("p").insert(() => document.createElement("div")); -``` - -Which is equivalent to: - -```js -d3.selectAll("p").select(function() { - return this.insertBefore(document.createElement("div"), null); -}); -``` - -In both cases, this method returns a new selection containing the appended elements. Each new element inherits the data of the current elements, if any, in the same manner as [*selection*.select](#selection_select). - -The specified *name* may have a namespace prefix, such as `svg:text` to specify a `text` attribute in the SVG namespace. See [namespaces](#namespaces) for the map of supported namespaces; additional namespaces can be registered by adding to the map. If no namespace is specified, the namespace will be inherited from the parent element; or, if the name is one of the known prefixes, the corresponding namespace will be used (for example, `svg` implies `svg:svg`). - -# selection.remove() [<>](https://github.com/d3/d3-selection/blob/master/src/selection/remove.js "Source") - -Removes the selected elements from the document. Returns this selection (the removed elements) which are now detached from the DOM. There is not currently a dedicated API to add removed elements back to the document; however, you can pass a function to [*selection*.append](#selection_append) or [*selection*.insert](#selection_insert) to re-add elements. - -# selection.clone([deep]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/clone.js "Source") - -Inserts clones of the selected elements immediately following the selected elements and returns a selection of the newly added clones. If *deep* is truthy, the descendant nodes of the selected elements will be cloned as well. Otherwise, only the elements themselves will be cloned. Equivalent to: - -```js -selection.select(function() { - return this.parentNode.insertBefore(this.cloneNode(deep), this.nextSibling); -}); -``` - -# selection.sort(compare) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/sort.js "Source") - -Returns a new selection that contains a copy of each group in this selection sorted according to the *compare* function. After sorting, re-inserts elements to match the resulting order (per [*selection*.order](#selection_order)). - -The compare function, which defaults to [ascending](https://github.com/d3/d3-array#ascending), is passed two elements’ data *a* and *b* to compare. It should return either a negative, positive, or zero value. If negative, then *a* should be before *b*; if positive, then *a* should be after *b*; otherwise, *a* and *b* are considered equal and the order is arbitrary. - -Note that sorting is not guaranteed to be stable; however, it is guaranteed to have the same behavior as your browser’s built-in [sort](https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/sort) method on arrays. - -# selection.order() [<>](https://github.com/d3/d3-selection/blob/master/src/selection/order.js "Source") - -Re-inserts elements into the document such that the document order of each group matches the selection order. This is equivalent to calling [*selection*.sort](#selection_sort) if the data is already sorted, but much faster. - -# selection.raise() [<>](https://github.com/d3/d3-selection/blob/master/src/selection/raise.js "Source") - -Re-inserts each selected element, in order, as the last child of its parent. Equivalent to: - -```js -selection.each(function() { - this.parentNode.appendChild(this); -}); -``` - -# selection.lower() [<>](https://github.com/d3/d3-selection/blob/master/src/selection/lower.js "Source") - -Re-inserts each selected element, in order, as the first child of its parent. Equivalent to: - -```js -selection.each(function() { - this.parentNode.insertBefore(this, this.parentNode.firstChild); -}); -``` - -# d3.create(name) [<>](https://github.com/d3/d3-selection/blob/master/src/create.js "Source") - -Given the specified element *name*, returns a single-element selection containing a detached element of the given name in the current document. This method assumes the HTML namespace, so you must specify a namespace explicitly when creating SVG or other non-HTML elements; see [namespace](#namespace) for details on supported namespace prefixes. - -```js -d3.create("svg") // equivalent to svg:svg -d3.create("svg:svg") // more explicitly -d3.create("svg:g") // an SVG G element -d3.create("g") // an HTML G (unknown) element -``` - -# d3.creator(name) [<>](https://github.com/d3/d3-selection/blob/master/src/creator.js "Source") - -Given the specified element *name*, returns a function which creates an element of the given name, assuming that `this` is the parent element. This method is used internally by [*selection*.append](#selection_append) and [*selection*.insert](#selection_insert) to create new elements. For example, this: - -```js -selection.append("div"); -``` - -Is equivalent to: - -```js -selection.append(d3.creator("div")); -``` - -See [namespace](#namespace) for details on supported namespace prefixes, such as for SVG elements. - -### Joining Data - -For an introduction to D3’s data joins, see the [*selection*.join notebook](https://observablehq.com/@d3/selection-join). Also see [Thinking With Joins](http://bost.ocks.org/mike/join/). - -# selection.data([data[, key]]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/data.js "Source") - -Binds the specified array of *data* with the selected elements, returning a new selection that represents the *update* selection: the elements successfully bound to data. Also defines the [enter](#selection_enter) and [exit](#selection_exit) selections on the returned selection, which can be used to add or remove elements to correspond to the new data. The specified *data* is an array of arbitrary values (*e.g.*, numbers or objects), or a function that returns an array of values for each group. When data is assigned to an element, it is stored in the property `__data__`, thus making the data “sticky” and available on re-selection. - -The *data* is specified **for each group** in the selection. If the selection has multiple groups (such as [d3.selectAll](#selectAll) followed by [*selection*.selectAll](#selection_selectAll)), then *data* should typically be specified as a function. This function will be evaluated for each group in order, being passed the group’s parent datum (*d*, which may be undefined), the group index (*i*), and the selection’s parent nodes (*nodes*), with *this* as the group’s parent element. - -In conjunction with [*selection*.join](#selection_join) (or more explicitly with [*selection*.enter](#selection_enter), [*selection*.exit](#selection_exit), [*selection*.append](#selection_append) and [*selection*.remove](#selection_remove)), *selection*.data can be used to enter, update and exit elements to match data. For example, to create an HTML table from a matrix of numbers: - -```js -const matrix = [ - [11975, 5871, 8916, 2868], - [ 1951, 10048, 2060, 6171], - [ 8010, 16145, 8090, 8045], - [ 1013, 990, 940, 6907] -]; - -d3.select("body") - .append("table") - .selectAll("tr") - .data(matrix) - .join("tr") - .selectAll("td") - .data(d => d) - .join("td") - .text(d => d); -``` - -In this example the *data* function is the identity function: for each table row, it returns the corresponding row from the data matrix. - -If a *key* function is not specified, then the first datum in *data* is assigned to the first selected element, the second datum to the second selected element, and so on. A *key* function may be specified to control which datum is assigned to which element, replacing the default join-by-index, by computing a string identifier for each datum and element. This key function is evaluated for each selected element, in order, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]); the returned string is the element’s key. The key function is then also evaluated for each new datum in *data*, being passed the current datum (*d*), the current index (*i*), and the group’s new *data*, with *this* as the group’s parent DOM element; the returned string is the datum’s key. The datum for a given key is assigned to the element with the matching key. If multiple elements have the same key, the duplicate elements are put into the exit selection; if multiple data have the same key, the duplicate data are put into the enter selection. - -For example, given this document: - -```html -
-
-
-
-
-
-``` - -You could join data by key as follows: - - -```js -const data = [ - {name: "Locke", number: 4}, - {name: "Reyes", number: 8}, - {name: "Ford", number: 15}, - {name: "Jarrah", number: 16}, - {name: "Shephard", number: 23}, - {name: "Kwon", number: 42} -]; - -d3.selectAll("div") - .data(data, function(d) { return d ? d.name : this.id; }) - .text(d => d.number); -``` - -This example key function uses the datum *d* if present, and otherwise falls back to the element’s id property. Since these elements were not previously bound to data, the datum *d* is null when the key function is evaluated on selected elements, and non-null when the key function is evaluated on the new data. - -The *update* and *enter* selections are returned in data order, while the *exit* selection preserves the selection order prior to the join. If a key function is specified, the order of elements in the selection may not match their order in the document; use [*selection*.order](#selection_order) or [*selection*.sort](#selection_sort) as needed. For more on how the key function affects the join, see [A Bar Chart, Part 2](http://bost.ocks.org/mike/bar/2/) and [Object Constancy](http://bost.ocks.org/mike/constancy/). - -If *data* is not specified, this method returns the array of data for the selected elements. - -This method cannot be used to clear bound data; use [*selection*.datum](#selection_datum) instead. - -# selection.join(enter[, update][, exit]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/join.js "Source") - -Appends, removes and reorders elements as necessary to match the data that was previously bound by [*selection*.data](#selection_data), returning the [merged](#selection_merge) enter and update selection. This method is a convenient alternative to the explicit [general update pattern](https://bl.ocks.org/mbostock/3808218), replacing [*selection*.enter](#selection_enter), [*selection*.exit](#selection_exit), [*selection*.append](#selection_append), [*selection*.remove](#selection_remove), and [*selection*.order](#selection_order). For example: - -```js -svg.selectAll("circle") - .data(data) - .join("circle") - .attr("fill", "none") - .attr("stroke", "black"); -``` - -The *enter* function may be specified as a string shorthand, as above, which is equivalent to [*selection*.append](#selection_append) with the given element name. Likewise, optional *update* and *exit* functions may be specified, which default to the identity function and calling [*selection*.remove](#selection_remove), respectively. The shorthand above is thus equivalent to: - -```js -svg.selectAll("circle") - .data(data) - .join( - enter => enter.append("circle"), - update => update, - exit => exit.remove() - ) - .attr("fill", "none") - .attr("stroke", "black"); -```` - -By passing separate functions on enter, update and exit, you have greater control over what happens. And by specifying a key function to [*selection*.data](#selection_data), you can minimize changes to the DOM to optimize performance. For example, to set different fill colors for enter and update: - -```js -svg.selectAll("circle") - .data(data) - .join( - enter => enter.append("circle").attr("fill", "green"), - update => update.attr("fill", "blue") - ) - .attr("stroke", "black"); -``` - -The selections returned by the *enter* and *update* functions are merged and then returned by *selection*.join. - -You also animate enter, update and exit by creating transitions inside the *enter*, *update* and *exit* functions. To avoid breaking the method chain, use *selection*.call to create transitions, or return an undefined enter or update selection to prevent merging: the return value of the *enter* and *update* functions specifies the two selections to merge and return by *selection*.join. - -For more, see the [*selection*.join notebook](https://observablehq.com/@d3/selection-join). - -# selection.enter() [<>](https://github.com/d3/d3-selection/blob/master/src/selection/enter.js "Source") - -Returns the enter selection: placeholder nodes for each datum that had no corresponding DOM element in the selection. (The enter selection is empty for selections not returned by [*selection*.data](#selection_data).) - -The enter selection is typically used to create “missing” elements corresponding to new data. For example, to create DIV elements from an array of numbers: - -```js -const div = d3.select("body") - .selectAll("div") - .data([4, 8, 15, 16, 23, 42]) - .enter().append("div") - .text(d => d); -``` - -If the body is initially empty, the above code will create six new DIV elements, append them to the body in-order, and assign their text content as the associated (string-coerced) number: - -```html -
4
-
8
-
15
-
16
-
23
-
42
-``` - -Conceptually, the enter selection’s placeholders are pointers to the parent element (in this example, the document body). The enter selection is typically only used transiently to append elements, and is often [merged](#selection_merge) with the update selection after appending, such that modifications can be applied to both entering and updating elements. - -# selection.exit() [<>](https://github.com/d3/d3-selection/blob/master/src/selection/exit.js "Source") - -Returns the exit selection: existing DOM elements in the selection for which no new datum was found. (The exit selection is empty for selections not returned by [*selection*.data](#selection_data).) - -The exit selection is typically used to remove “superfluous” elements corresponding to old data. For example, to update the DIV elements created previously with a new array of numbers: - -```js -div = div.data([1, 2, 4, 8, 16, 32], d => d); -``` - -Since a key function was specified (as the identity function), and the new data contains the numbers [4, 8, 16] which match existing elements in the document, the update selection contains three DIV elements. Leaving those elements as-is, we can append new elements for [1, 2, 32] using the enter selection: - -```js -div.enter().append("div").text(d => d); -``` - -Likewise, to remove the exiting elements [15, 23, 42]: - -```js -div.exit().remove(); -``` - -Now the document body looks like this: - -```html -
1
-
2
-
4
-
8
-
16
-
32
-``` - -The order of the DOM elements matches the order of the data because the old data’s order and the new data’s order were consistent. If the new data’s order is different, use [*selection*.order](#selection_order) to reorder the elements in the DOM. See the [General Update Pattern](http://bl.ocks.org/mbostock/3808218) example thread for more on data joins. - -# selection.datum([value]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/datum.js "Source") - -Gets or sets the bound data for each selected element. Unlike [*selection*.data](#selection_data), this method does not compute a join and does not affect indexes or the enter and exit selections. - -If a *value* is specified, sets the element’s bound data to the specified value on all selected elements. If the *value* is a constant, all elements are given the same datum; otherwise, if the *value* is a function, it is evaluated for each selected element, in order, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]). The function is then used to set each element’s new data. A null value will delete the bound data. - -If a *value* is not specified, returns the bound datum for the first (non-null) element in the selection. This is generally useful only if you know the selection contains exactly one element. - -This method is useful for accessing HTML5 [custom data attributes](http://www.w3.org/TR/html5/dom.html#custom-data-attribute). For example, given the following elements: - -```html -
    -
  • Shawn Allen
    • -
  • Mike Bostock
    • -
-``` - -You can expose the custom data attributes by setting each element’s data as the built-in [dataset](http://www.w3.org/TR/html5/dom.html#dom-dataset) property: - -```js -selection.datum(function() { return this.dataset; }) -``` - -### Handling Events - -For interaction, selections allow listening for and dispatching of events. - -# selection.on(typenames[, listener[, options]]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/on.js "Source") - -Adds or removes a *listener* to each selected element for the specified event *typenames*. The *typenames* is a string event type, such as `click`, `mouseover`, or `submit`; any [DOM event type](https://developer.mozilla.org/en-US/docs/Web/Events#Standard_events) supported by your browser may be used. The type may be optionally followed by a period (`.`) and a name; the optional name allows multiple callbacks to be registered to receive events of the same type, such as `click.foo` and `click.bar`. To specify multiple typenames, separate typenames with spaces, such as `input change` or `click.foo click.bar`. - -When a specified event is dispatched on a selected element, the specified *listener* will be evaluated for the element, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]). Listeners always see the latest datum for their element, but the index is a property of the selection and is fixed when the listener is assigned; to update the index, re-assign the listener. To access the current event within a listener, use [d3.event](#event). - -If an event listener was previously registered for the same *typename* on a selected element, the old listener is removed before the new listener is added. To remove a listener, pass null as the *listener*. To remove all listeners for a given name, pass null as the *listener* and `.foo` as the *typename*, where `foo` is the name; to remove all listeners with no name, specify `.` as the *typename*. - -An optional *options* object may specify characteristics about the event listener, such as whether it is capturing or passive; see [*element*.addEventListener](https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/addEventListener). - -If a *listener* is not specified, returns the currently-assigned listener for the specified event *typename* on the first (non-null) selected element, if any. If multiple typenames are specified, the first matching listener is returned. - -# selection.dispatch(type[, parameters]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/dispatch.js "Source") - -Dispatches a [custom event](http://www.w3.org/TR/dom/#interface-customevent) of the specified *type* to each selected element, in order. An optional *parameters* map may be specified to set additional properties of the event. It may contain the following fields: - -* [`bubbles`](https://www.w3.org/TR/dom/#dom-event-bubbles) - if true, the event is dispatched to ancestors in reverse tree order. -* [`cancelable`](https://www.w3.org/TR/dom/#dom-event-cancelable) - if true, *event*.preventDefault is allowed. -* [`detail`](https://www.w3.org/TR/dom/#dom-customevent-detail) - any custom data associated with the event. - -If *parameters* is a function, it is evaluated for each selected element, in order, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]). It must return the parameters map for the current element. - -# d3.event - -The current [event](https://developer.mozilla.org/en-US/docs/DOM/event), if any. This is set during the invocation of an event listener, and is reset after the listener terminates. Use this to access standard event fields such as [*event*.timeStamp](https://www.w3.org/TR/dom/#dom-event-timestamp) and methods such as [*event*.preventDefault](https://www.w3.org/TR/dom/#dom-event-preventdefault). While you can use the native [*event*.pageX](https://developer.mozilla.org/en/DOM/event.pageX) and [*event*.pageY](https://developer.mozilla.org/en/DOM/event.pageY), it is often more convenient to transform the event position to the local coordinate system of the container that received the event using [d3.mouse](#mouse), [d3.touch](#touch) or [d3.touches](#touches). - -If you use Babel, Webpack, or another ES6-to-ES5 bundler, be aware that the value of d3.event changes during an event! An import of d3.event must be a [live binding](http://www.2ality.com/2015/07/es6-module-exports.html), so you may need to configure the bundler to import from D3’s ES6 modules rather than from the generated UMD bundle; not all bundlers observe [jsnext:main](https://github.com/rollup/rollup/wiki/jsnext:main). Also beware of conflicts with the [*window*.event](https://developer.mozilla.org/en-US/docs/Web/API/Window/event) global. - -# d3.customEvent(event, listener[, that[, arguments]]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/on.js#L98 "Source") - -Invokes the specified *listener*, using the specified *that* `this` context and passing the specified *arguments*, if any. During the invocation, [d3.event](#event) is set to the specified *event*; after the listener returns (or throws an error), d3.event is restored to its previous value. In addition, sets *event*.sourceEvent to the prior value of d3.event, allowing custom events to retain a reference to the originating native event. Returns the value returned by the *listener*. - -# d3.mouse(container) [<>](https://github.com/d3/d3-selection/blob/master/src/mouse.js "Source") - -Returns the *x* and *y* coordinates of the [current event](#event) relative to the specified *container*. The container may be an HTML or SVG container element, such as a [G element](http://www.w3.org/TR/SVG/struct.html#Groups) or an [SVG element](http://www.w3.org/TR/SVG/struct.html#SVGElement). The coordinates are returned as a two-element array of numbers [*x*, *y*]. - -# d3.touch(container[, touches], identifier) [<>](https://github.com/d3/d3-selection/blob/master/src/touch.js "Source") - -Returns the *x* and *y* coordinates of the touch with the specified *identifier* associated with the [current event](#event) relative to the specified *container*. The container may be an HTML or SVG container element, such as a [G element](http://www.w3.org/TR/SVG/struct.html#Groups) or an [SVG element](http://www.w3.org/TR/SVG/struct.html#SVGElement). The coordinates are returned as a two-element array of numbers [*x*, *y*]. If there is no touch with the specified identifier in *touches*, returns null; this can be useful for ignoring touchmove events where the only some touches have moved. If *touches* is not specified, it defaults to the current event’s [changedTouches](http://developer.apple.com/library/safari/documentation/UserExperience/Reference/TouchEventClassReference/TouchEvent/TouchEvent.html#//apple_ref/javascript/instp/TouchEvent/changedTouches) property. - -# d3.touches(container[, touches]) [<>](https://github.com/d3/d3-selection/blob/master/src/touches.js "Source") - -Returns the *x* and *y* coordinates of the touches associated with the [current event](#event) relative to the specified *container*. The container may be an HTML or SVG container element, such as a [G element](http://www.w3.org/TR/SVG/struct.html#Groups) or an [SVG element](http://www.w3.org/TR/SVG/struct.html#SVGElement). The coordinates are returned as an array of two-element arrays of numbers \[\[*x1*, *y1*], [*x2*, *y2*], …\]. If *touches* is not specified, it defaults to the current event’s [touches](http://developer.apple.com/library/safari/documentation/UserExperience/Reference/TouchEventClassReference/TouchEvent/TouchEvent.html#//apple_ref/javascript/instp/TouchEvent/touches) property. - -# d3.clientPoint(container, event) [<>](https://github.com/d3/d3-selection/blob/master/src/point.js "Source") - -Returns the *x* and *y* coordinates of the specified *event* relative to the specified *container*. (The *event* may also be a [touch](https://www.w3.org/TR/touch-events/#touch-interface).) The container may be an HTML or SVG container element, such as a [G element](http://www.w3.org/TR/SVG/struct.html#Groups) or an [SVG element](http://www.w3.org/TR/SVG/struct.html#SVGElement). The coordinates are returned as a two-element array of numbers [*x*, *y*]. - -### Control Flow - -For advanced usage, selections provide methods for custom control flow. - -# selection.each(function) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/each.js "Source") - -Invokes the specified *function* for each selected element, in order, being passed the current datum (*d*), the current index (*i*), and the current group (*nodes*), with *this* as the current DOM element (*nodes*[*i*]). This method can be used to invoke arbitrary code for each selected element, and is useful for creating a context to access parent and child data simultaneously, such as: - -```js -parent.each(function(p, j) { - d3.select(this) - .selectAll(".child") - .text(d => `child ${d.name} of ${p.name}`); -}); -``` - -See [Sized Donut Multiples](http://bl.ocks.org/mbostock/4c5fad723c87d2fd8273) for an example. - -# selection.call(function[, arguments…]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/call.js "Source") - -Invokes the specified *function* exactly once, passing in this selection along with any optional *arguments*. Returns this selection. This is equivalent to invoking the function by hand but facilitates method chaining. For example, to set several styles in a reusable function: - -```js -function name(selection, first, last) { - selection - .attr("first-name", first) - .attr("last-name", last); -} -``` - -Now say: - -```js -d3.selectAll("div").call(name, "John", "Snow"); -``` - -This is roughly equivalent to: - -```js -name(d3.selectAll("div"), "John", "Snow"); -``` - -The only difference is that *selection*.call always returns the *selection* and not the return value of the called *function*, `name`. - -# selection.empty() [<>](https://github.com/d3/d3-selection/blob/master/src/selection/empty.js "Source") - -Returns true if this selection contains no (non-null) elements. - -# selection.nodes() [<>](https://github.com/d3/d3-selection/blob/master/src/selection/nodes.js "Source") - -Returns an array of all (non-null) elements in this selection. - -# selection.node() [<>](https://github.com/d3/d3-selection/blob/master/src/selection/node.js "Source") - -Returns the first (non-null) element in this selection. If the selection is empty, returns null. - -# selection.size() [<>](https://github.com/d3/d3-selection/blob/master/src/selection/size.js "Source") - -Returns the total number of elements in this selection. - -### Local Variables - -D3 locals allow you to define local state independent of data. For instance, when rendering [small multiples](http://bl.ocks.org/mbostock/e1192fe405703d8321a5187350910e08) of time-series data, you might want the same *x*-scale for all charts but distinct *y*-scales to compare the relative performance of each metric. D3 locals are scoped by DOM elements: on set, the value is stored on the given element; on get, the value is retrieved from given element or the nearest ancestor that defines it. - -# d3.local() [<>](https://github.com/d3/d3-selection/blob/master/src/local.js "Source") - -Declares a new local variable. For example: - -```js -const foo = d3.local(); -``` - -Like `var`, each local is a distinct symbolic reference; unlike `var`, the value of each local is also scoped by the DOM. - -# local.set(node, value) [<>](https://github.com/d3/d3-selection/blob/master/src/local.js#L18 "Source") - -Sets the value of this local on the specified *node* to the *value*, and returns the specified *value*. This is often performed using [*selection*.each](#selection_each): - -```js -selection.each(function(d) { foo.set(this, d.value); }); -``` - -If you are just setting a single variable, consider using [*selection*.property](#selection_property): - -```js -selection.property(foo, d => d.value); -``` - -# local.get(node) [<>](https://github.com/d3/d3-selection/blob/master/src/local.js#L13 "Source") - -Returns the value of this local on the specified *node*. If the *node* does not define this local, returns the value from the nearest ancestor that defines it. Returns undefined if no ancestor defines this local. - -# local.remove(node) [<>](https://github.com/d3/d3-selection/blob/master/src/local.js#L21 "Source") - -Deletes this local’s value from the specified *node*. Returns true if the *node* defined this local prior to removal, and false otherwise. If ancestors also define this local, those definitions are unaffected, and thus [*local*.get](#local_get) will still return the inherited value. - -# local.toString() [<>](https://github.com/d3/d3-selection/blob/master/src/local.js#L24 "Source") - -Returns the automatically-generated identifier for this local. This is the name of the property that is used to store the local’s value on elements, and thus you can also set or get the local’s value using *element*[*local*] or by using [*selection*.property](#selection_property). - -### Namespaces - -XML namespaces are fun! Right? Fortunately you can mostly ignore them. - -# d3.namespace(name) [<>](https://github.com/d3/d3-selection/blob/master/src/namespace.js "Source") - -Qualifies the specified *name*, which may or may not have a namespace prefix. If the name contains a colon (`:`), the substring before the colon is interpreted as the namespace prefix, which must be registered in [d3.namespaces](#namespaces). Returns an object `space` and `local` attributes describing the full namespace URL and the local name. For example: - -```js -d3.namespace("svg:text"); // {space: "http://www.w3.org/2000/svg", local: "text"} -``` - -If the name does not contain a colon, this function merely returns the input name. - -# d3.namespaces [<>](https://github.com/d3/d3-selection/blob/master/src/namespaces.js "Source") - -The map of registered namespace prefixes. The initial value is: - -```js -{ - svg: "http://www.w3.org/2000/svg", - xhtml: "http://www.w3.org/1999/xhtml", - xlink: "http://www.w3.org/1999/xlink", - xml: "http://www.w3.org/XML/1998/namespace", - xmlns: "http://www.w3.org/2000/xmlns/" -} -``` - -Additional prefixes may be assigned as needed to create elements or attributes in other namespaces. diff --git a/node_modules/d3-selection/dist/d3-selection.js b/node_modules/d3-selection/dist/d3-selection.js deleted file mode 100644 index 0c8e21ef5fbb883e6911d9932fe28271ce2be3d7..0000000000000000000000000000000000000000 --- a/node_modules/d3-selection/dist/d3-selection.js +++ /dev/null @@ -1,989 +0,0 @@ -// https://d3js.org/d3-selection/ v1.4.1 Copyright 2019 Mike Bostock -(function (global, factory) { -typeof exports === 'object' && typeof module !== 'undefined' ?

However, you can define your own symbol type implementation should none of the built-in types satisfy your needs using the following interface. You can also use this low-level interface with a built-in symbol type as an alternative to the symbol generator. - -# symbolType.draw(context, size) - -Renders this symbol type to the specified *context* with the specified *size* in square pixels. The *context* implements the [CanvasPathMethods](http://www.w3.org/TR/2dcontext/#canvaspathmethods) interface. (Note that this is a subset of the CanvasRenderingContext2D interface!) - -### Stacks - -[Stacked Bar Chart](https://observablehq.com/@d3/stacked-bar-chart)[Streamgraph](https://observablehq.com/@mbostock/streamgraph-transitions) - -Some shape types can be stacked, placing one shape adjacent to another. For example, a bar chart of monthly sales might be broken down into a multi-series bar chart by product category, stacking bars vertically. This is equivalent to subdividing a bar chart by an ordinal dimension (such as product category) and applying a color encoding. - -Stacked charts can show overall value and per-category value simultaneously; however, it is typically harder to compare across categories, as only the bottom layer of the stack is aligned. So, chose the [stack order](#stack_order) carefully, and consider a [streamgraph](#stackOffsetWiggle). (See also [grouped charts](https://observablehq.com/@d3/grouped-bar-chart).) - -Like the [pie generator](#pies), the stack generator does not produce a shape directly. Instead it computes positions which you can then pass to an [area generator](#areas) or use directly, say to position bars. - -# d3.stack() · [Source](https://github.com/d3/d3-shape/blob/master/src/stack.js) - -Constructs a new stack generator with the default settings. - -# stack(data[, arguments…]) · [Source](https://github.com/d3/d3-shape/blob/master/src/stack.js) - -Generates a stack for the given array of *data*, returning an array representing each series. Any additional *arguments* are arbitrary; they are simply propagated to accessors along with the `this` object. - -The series are determined by the [keys accessor](#stack_keys); each series *i* in the returned array corresponds to the *i*th key. Each series is an array of points, where each point *j* corresponds to the *j*th element in the input *data*. Lastly, each point is represented as an array [*y0*, *y1*] where *y0* is the lower value (baseline) and *y1* is the upper value (topline); the difference between *y0* and *y1* corresponds to the computed [value](#stack_value) for this point. The key for each series is available as *series*.key, and the [index](#stack_order) as *series*.index. The input data element for each point is available as *point*.data. - -For example, consider the following table representing monthly sales of fruits: - -Month | Apples | Bananas | Cherries | Dates ---------|--------|---------|----------|------- - 1/2015 | 3840 | 1920 | 960 | 400 - 2/2015 | 1600 | 1440 | 960 | 400 - 3/2015 | 640 | 960 | 640 | 400 - 4/2015 | 320 | 480 | 640 | 400 - -This might be represented in JavaScript as an array of objects: - -```js -var data = [ - {month: new Date(2015, 0, 1), apples: 3840, bananas: 1920, cherries: 960, dates: 400}, - {month: new Date(2015, 1, 1), apples: 1600, bananas: 1440, cherries: 960, dates: 400}, - {month: new Date(2015, 2, 1), apples: 640, bananas: 960, cherries: 640, dates: 400}, - {month: new Date(2015, 3, 1), apples: 320, bananas: 480, cherries: 640, dates: 400} -]; -``` - -To produce a stack for this data: - -```js -var stack = d3.stack() - .keys(["apples", "bananas", "cherries", "dates"]) - .order(d3.stackOrderNone) - .offset(d3.stackOffsetNone); - -var series = stack(data); -``` - -The resulting array has one element per *series*. Each series has one point per month, and each point has a lower and upper value defining the baseline and topline: - -```js -[ - [[ 0, 3840], [ 0, 1600], [ 0, 640], [ 0, 320]], // apples - [[3840, 5760], [1600, 3040], [ 640, 1600], [ 320, 800]], // bananas - [[5760, 6720], [3040, 4000], [1600, 2240], [ 800, 1440]], // cherries - [[6720, 7120], [4000, 4400], [2240, 2640], [1440, 1840]], // dates -] -``` - -Each series in then typically passed to an [area generator](#areas) to render an area chart, or used to construct rectangles for a bar chart. - -# stack.keys([keys]) · [Source](https://github.com/d3/d3-shape/blob/master/src/stack.js) - -If *keys* is specified, sets the keys accessor to the specified function or array and returns this stack generator. If *keys* is not specified, returns the current keys accessor, which defaults to the empty array. A series (layer) is [generated](#_stack) for each key. Keys are typically strings, but they may be arbitrary values. The series’ key is passed to the [value accessor](#stack_value), along with each data point, to compute the point’s value. - -# stack.value([value]) · [Source](https://github.com/d3/d3-shape/blob/master/src/stack.js) - -If *value* is specified, sets the value accessor to the specified function or number and returns this stack generator. If *value* is not specified, returns the current value accessor, which defaults to: - -```js -function value(d, key) { - return d[key]; -} -``` - -Thus, by default the stack generator assumes that the input data is an array of objects, with each object exposing named properties with numeric values; see [*stack*](#_stack) for an example. - -# stack.order([order]) · [Source](https://github.com/d3/d3-shape/blob/master/src/stack.js) - -If *order* is specified, sets the order accessor to the specified function or array and returns this stack generator.

See [stack orders](#stack-orders) for the built-in orders. - -If *order* is a function, it is passed the generated series array and must return an array of numeric indexes representing the stack order. For example, the default order is defined as: - -```js -function orderNone(series) { - var n = series.length, o = new Array(n); - while (--n >= 0) o[n] = n; - return o; -} -``` - -The stack order is computed prior to the [offset](#stack_offset); thus, the lower value for all points is zero at the time the order is computed. The index attribute for each series is also not set until after the order is computed. - -# stack.offset([offset]) · [Source](https://github.com/d3/d3-shape/blob/master/src/stack.js) - -If *offset* is specified, sets the offset accessor to the specified function or array and returns this stack generator. If *offset* is not specified, returns the current offset acccesor, which defaults to [stackOffsetNone](#stackOffsetNone); this uses a zero baseline. See [stack offsets](#stack-offsets) for the built-in offsets. - -If *offset* is a function, it is passed the generated series array and the order index array. The offset function is then responsible for updating the lower and upper values in the series array to layout the stack. For example, the default offset is defined as: - -```js -function offsetNone(series, order) { - if (!((n = series.length) > 1)) return; - for (var i = 1, s0, s1 = series[order[0]], n, m = s1.length; i < n; ++i) { - s0 = s1, s1 = series[order[i]]; - for (var j = 0; j < m; ++j) { - s1[j][1] += s1[j][0] = s0[j][1]; - } - } -} -``` - -### Stack Orders - -Stack orders are typically not used directly, but are instead passed to [*stack*.order](#stack_order). - -# d3.stackOrderAppearance(series) · [Source](https://github.com/d3/d3-shape/blob/master/src/order/appearance.js) - -Returns a series order such that the earliest series (according to the maximum value) is at the bottom. - -# d3.stackOrderAscending(series) · [Source](https://github.com/d3/d3-shape/blob/master/src/order/ascending.js) - -Returns a series order such that the smallest series (according to the sum of values) is at the bottom. - -# d3.stackOrderDescending(series) · [Source](https://github.com/d3/d3-shape/blob/master/src/order/descending.js) - -Returns a series order such that the largest series (according to the sum of values) is at the bottom. - -# d3.stackOrderInsideOut(series) · [Source](https://github.com/d3/d3-shape/blob/master/src/order/insideOut.js) - -Returns a series order such that the earliest series (according to the maximum value) are on the inside and the later series are on the outside.

In the [Gregorian calendar](https://en.wikipedia.org/wiki/Gregorian_calendar), for example, most months have 31 days but some have 28, 29 or 30; most years have 365 days but [leap years](https://en.wikipedia.org/wiki/Leap_year) have 366; and with [daylight saving](https://en.wikipedia.org/wiki/Daylight_saving_time), most days have 24 hours but some have 23 or 25. Adding to complexity, daylight saving conventions vary around the world. - -As a result of these temporal peculiarities, it can be difficult to perform seemingly-trivial tasks. For example, if you want to compute the number of days that have passed between two dates, you can’t simply subtract and divide by 24 hours (86,400,000 ms): - -```js -var start = new Date(2015, 02, 01), // Sun Mar 01 2015 00:00:00 GMT-0800 (PST) - end = new Date(2015, 03, 01); // Wed Apr 01 2015 00:00:00 GMT-0700 (PDT) -(end - start) / 864e5; // 30.958333333333332, oops! -``` - -You can, however, use [d3.timeDay](#timeDay).[count](#interval_count): - -```js -d3.timeDay.count(start, end); // 31 -``` - -The [day](#day) [interval](#api-reference) is one of several provided by d3-time. Each interval represents a conventional unit of time—[hours](#timeHour), [weeks](#timeWeek), [months](#timeMonth), *etc.*—and has methods to calculate boundary dates. For example, [d3.timeDay](#timeDay) computes midnight (typically 12:00 AM local time) of the corresponding day. In addition to [rounding](#interval_round) and [counting](#interval_count), intervals can also be used to generate arrays of boundary dates. For example, to compute each Sunday in the current month: - -```js -var now = new Date; -d3.timeWeek.range(d3.timeMonth.floor(now), d3.timeMonth.ceil(now)); -// [Sun Jun 07 2015 00:00:00 GMT-0700 (PDT), -// Sun Jun 14 2015 00:00:00 GMT-0700 (PDT), -// Sun Jun 21 2015 00:00:00 GMT-0700 (PDT), -// Sun Jun 28 2015 00:00:00 GMT-0700 (PDT)] -``` - -The d3-time module does not implement its own calendaring system; it merely implements a convenient API for calendar math on top of ECMAScript [Date](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date). Thus, it ignores leap seconds and can only work with the local time zone and [Coordinated Universal Time](https://en.wikipedia.org/wiki/Coordinated_Universal_Time) (UTC). - -This module is used by D3’s time scales to generate sensible ticks, by D3’s time format, and can also be used directly to do things like [calendar layouts](http://bl.ocks.org/mbostock/4063318). - -## Installing - -If you use NPM, `npm install d3-time`. Otherwise, download the [latest release](https://github.com/d3/d3-time/releases/latest). You can also load directly from [d3js.org](https://d3js.org), either as a [standalone library](https://d3js.org/d3-time.v1.min.js) or as part of [D3 4.0](https://github.com/d3/d3). AMD, CommonJS, and vanilla environments are supported.

Furthermore, the returned date is the minimum expressible value of the associated interval, such that *interval*.floor(*interval*.floor(*date*) - 1) returns the preceeding interval boundary date. - -Note that the `==` and `===` operators do not compare by value with [Date](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date) objects, and thus you cannot use them to tell whether the specified *date* has already been floored. Instead, coerce to a number and then compare: - -```js -// Returns true if the specified date is a day boundary. -function isDay(date) { - return +d3.timeDay.floor(date) === +date; -} -``` - -This is more reliable than testing whether the time is 12:00 AM, as in some time zones midnight may not exist due to daylight saving. - -# interval.round(date) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L16 "Source") - -Returns a new date representing the closest interval boundary date to *date*. For example, [d3.timeDay](#timeDay).round(*date*) typically returns 12:00 AM local time on the given *date* if it is on or before noon, and 12:00 AM of the following day if it is after noon. - -This method is idempotent: if the specified *date* is already rounded to the current interval, a new date with an identical time is returned. - -# interval.ceil(date) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L12 "Source") - -Returns a new date representing the earliest interval boundary date after or equal to *date*. For example, [d3.timeDay](#timeDay).ceil(*date*) typically returns 12:00 AM local time on the date following the given *date*. - -This method is idempotent: if the specified *date* is already ceilinged to the current interval, a new date with an identical time is returned. Furthermore, the returned date is the maximum expressible value of the associated interval, such that *interval*.ceil(*interval*.ceil(*date*) + 1) returns the following interval boundary date. - -# interval.offset(date[, step]) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L22 "Source") - -Returns a new date equal to *date* plus *step* intervals. If *step* is not specified it defaults to 1. If *step* is negative, then the returned date will be before the specified *date*; if *step* is zero, then a copy of the specified *date* is returned; if *step* is not an integer, it is [floored](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/floor). This method does not round the specified *date* to the interval. For example, if *date* is today at 5:34 PM, then [d3.timeDay](#timeDay).offset(*date*, 1) returns 5:34 PM tomorrow (even if daylight saving changes!). - -# interval.range(start, stop[, step]) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L26 "Source") - -Returns an array of dates representing every interval boundary after or equal to *start* (inclusive) and before *stop* (exclusive). If *step* is specified, then every *step*th boundary will be returned; for example, for the [d3.timeDay](#timeDay) interval a *step* of 2 will return every other day. If *step* is not an integer, it is [floored](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/floor). - -The first date in the returned array is the earliest boundary after or equal to *start*; subsequent dates are [offset](#interval_offset) by *step* intervals and [floored](#interval_floor). Thus, two overlapping ranges may be consistent. For example, this range contains odd days: - -```js -d3.timeDay.range(new Date(2015, 0, 1), new Date(2015, 0, 7), 2); -// [Thu Jan 01 2015 00:00:00 GMT-0800 (PST), -// Sat Jan 03 2015 00:00:00 GMT-0800 (PST), -// Mon Jan 05 2015 00:00:00 GMT-0800 (PST)] -``` - -While this contains even days: - -```js -d3.timeDay.range(new Date(2015, 0, 2), new Date(2015, 0, 8), 2); -// [Fri Jan 02 2015 00:00:00 GMT-0800 (PST), -// Sun Jan 04 2015 00:00:00 GMT-0800 (PST), -// Tue Jan 06 2015 00:00:00 GMT-0800 (PST)] -``` - -To make ranges consistent when a *step* is specified, use [*interval*.every](#interval_every) instead. - -# interval.filter(test) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L35 "Source") - -Returns a new interval that is a filtered subset of this interval using the specified *test* function. The *test* function is passed a date and should return true if and only if the specified date should be considered part of the interval. For example, to create an interval that returns the 1st, 11th, 21th and 31th (if it exists) of each month: - -```js -var i = d3.timeDay.filter(function(d) { return (d.getDate() - 1) % 10 === 0; }); -``` - -The returned filtered interval does not support [*interval*.count](#interval_count). See also [*interval*.every](#interval_every). - -# interval.every(step) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L50 "Source") - -Returns a [filtered](#interval_filter) view of this interval representing every *step*th date. The meaning of *step* is dependent on this interval’s parent interval as defined by the field function. For example, [d3.timeMinute](#timeMinute).every(15) returns an interval representing every fifteen minutes, starting on the hour: :00, :15, :30, :45, etc. Note that for some intervals, the resulting dates may not be uniformly-spaced; [d3.timeDay](#timeDay)’s parent interval is [d3.timeMonth](#timeMonth), and thus the interval number resets at the start of each month. If *step* is not valid, returns null. If *step* is one, returns this interval. - -This method can be used in conjunction with [*interval*.range](#interval_range) to ensure that two overlapping ranges are consistent. For example, this range contains odd days: - -```js -d3.timeDay.every(2).range(new Date(2015, 0, 1), new Date(2015, 0, 7)); -// [Thu Jan 01 2015 00:00:00 GMT-0800 (PST), -// Sat Jan 03 2015 00:00:00 GMT-0800 (PST), -// Mon Jan 05 2015 00:00:00 GMT-0800 (PST)] -``` - -As does this one: - -```js -d3.timeDay.every(2).range(new Date(2015, 0, 2), new Date(2015, 0, 8)); -// [Sat Jan 03 2015 00:00:00 GMT-0800 (PST), -// Mon Jan 05 2015 00:00:00 GMT-0800 (PST), -// Wed Jan 07 2015 00:00:00 GMT-0800 (PST)] -``` - -The returned filtered interval does not support [*interval*.count](#interval_count). See also [*interval*.filter](#interval_filter). - -# interval.count(start, end) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L44 "Source") - -Returns the number of interval boundaries after *start* (exclusive) and before or equal to *end* (inclusive). Note that this behavior is slightly different than [*interval*.range](#interval_range) because its purpose is to return the zero-based number of the specified *end* date relative to the specified *start* date. For example, to compute the current zero-based day-of-year number: - -```js -var now = new Date; -d3.timeDay.count(d3.timeYear(now), now); // 177 -``` - -Likewise, to compute the current zero-based week-of-year number for weeks that start on Sunday: - -```js -d3.timeSunday.count(d3.timeYear(now), now); // 25 -``` - -# d3.timeInterval(floor, offset[, count[, field]]) [<>](https://github.com/d3/d3-time/blob/master/src/interval.js#L4 "Source") - -Constructs a new custom interval given the specified *floor* and *offset* functions and an optional *count* function. - -The *floor* function takes a single date as an argument and rounds it down to the nearest interval boundary. - -The *offset* function takes a date and an integer step as arguments and advances the specified date by the specified number of boundaries; the step may be positive, negative or zero. - -The optional *count* function takes a start date and an end date, already floored to the current interval, and returns the number of boundaries between the start (exclusive) and end (inclusive). If a *count* function is not specified, the returned interval does not expose [*interval*.count](#interval_count) or [*interval*.every](#interval_every) methods. Note: due to an internal optimization, the specified *count* function must not invoke *interval*.count on other time intervals. - -The optional *field* function takes a date, already floored to the current interval, and returns the field value of the specified date, corresponding to the number of boundaries between this date (exclusive) and the latest previous parent boundary. For example, for the [d3.timeDay](#timeDay) interval, this returns the number of days since the start of the month. If a *field* function is not specified, it defaults to counting the number of interval boundaries since the UNIX epoch of January 1, 1970 UTC. The *field* function defines the behavior of [*interval*.every](#interval_every). - -### Intervals - -The following intervals are provided: - -# d3.timeMillisecond [<>](https://github.com/d3/d3-time/blob/master/src/millisecond.js "Source") -

Internally, it uses [requestAnimationFrame](https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame) for fluid animation (if available), switching to [setTimeout](https://developer.mozilla.org/en-US/docs/Web/API/WindowTimers/setTimeout) for delays longer than 24ms. - -## Installing - -If you use NPM, `npm install d3-timer`. Otherwise, download the [latest release](https://github.com/d3/d3-timer/releases/latest). You can also load directly from [d3js.org](https://d3js.org), either as a [standalone library](https://d3js.org/d3-timer.v1.min.js) or as part of [D3](https://github.com/d3/d3). AMD, CommonJS, and vanilla environments are supported. In vanilla, a `d3` global is exported: - -```html - - -``` - -## API Reference - -# d3.now() [<>](https://github.com/d3/d3-timer/blob/master/src/timer.js#L15 "Source") - -Returns the current time as defined by [performance.now](https://developer.mozilla.org/en-US/docs/Web/API/Performance/now) if available, and [Date.now](https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Date/now) if not. The current time is updated at the start of a frame; it is thus consistent during the frame, and any timers scheduled during the same frame will be synchronized. If this method is called outside of a frame, such as in response to a user event, the current time is calculated and then fixed until the next frame, again ensuring consistent timing during event handling. - -# d3.timer(callback[, delay[, time]]) [<>](https://github.com/d3/d3-timer/blob/master/src/timer.js#L52 "Source") - -Schedules a new timer, invoking the specified *callback* repeatedly until the timer is [stopped](#timer_stop). An optional numeric *delay* in milliseconds may be specified to invoke the given *callback* after a delay; if *delay* is not specified, it defaults to zero. The delay is relative to the specified *time* in milliseconds; if *time* is not specified, it defaults to [now](#now). - -The *callback* is passed the (apparent) *elapsed* time since the timer became active. For example: - -```js -var t = d3.timer(function(elapsed) { - console.log(elapsed); - if (elapsed > 200) t.stop(); -}, 150); -``` - -This produces roughly the following console output: - -``` -3 -25 -48 -65 -85 -106 -125 -146 -167 -189 -209 -``` - -(The exact values may vary depending on your JavaScript runtime and what else your computer is doing.) Note that the first *elapsed* time is 3ms: this is the elapsed time since the timer started, not since the timer was scheduled. Here the timer started 150ms after it was scheduled due to the specified delay. The apparent *elapsed* time may be less than the true *elapsed* time if the page is backgrounded and [requestAnimationFrame](https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame) is paused; in the background, apparent time is frozen. - -If [timer](#timer) is called within the callback of another timer, the new timer callback (if eligible as determined by the specified *delay* and *time*) will be invoked immediately at the end of the current frame, rather than waiting until the next frame. Within a frame, timer callbacks are guaranteed to be invoked in the order they were scheduled, regardless of their start time. - -# timer.restart(callback[, delay[, time]]) [<>](https://github.com/d3/d3-timer/blob/master/src/timer.js#L31 "Source") - -Restart a timer with the specified *callback* and optional *delay* and *time*. This is equivalent to stopping this timer and creating a new timer with the specified arguments, although this timer retains the original invocation priority. - -# timer.stop() [<>](https://github.com/d3/d3-timer/blob/master/src/timer.js#L43 "Source") - -Stops this timer, preventing subsequent callbacks. This method has no effect if the timer has already stopped. - -# d3.timerFlush() [<>](https://github.com/d3/d3-timer/blob/master/src/timer.js#L58 "Source") - -Immediately invoke any eligible timer callbacks. Note that zero-delay timers are normally first executed after one frame (~17ms). This can cause a brief flicker because the browser renders the page twice: once at the end of the first event loop, then again immediately on the first timer callback. By flushing the timer queue at the end of the first event loop, you can run any zero-delay timers immediately and avoid the flicker. - -# d3.timeout(callback[, delay[, time]]) [<>](https://github.com/d3/d3-timer/blob/master/src/timeout.js "Source") - -Like [timer](#timer), except the timer automatically [stops](#timer_stop) on its first callback. A suitable replacement for [setTimeout](https://developer.mozilla.org/en-US/docs/Web/API/WindowTimers/setTimeout) that is guaranteed to not run in the background. The *callback* is passed the elapsed time. - -# d3.interval(callback[, delay[, time]]) [<>](https://github.com/d3/d3-timer/blob/master/src/interval.js "Source") - -Like [timer](#timer), except the *callback* is invoked only every *delay* milliseconds; if *delay* is not specified, this is equivalent to [timer](#timer).

For example: - -```js -d3.select("body") - .transition() - .style("background-color", "red"); -``` - -Transitions support most selection methods (such as [*transition*.attr](#transition_attr) and [*transition*.style](#transition_style) in place of [*selection*.attr](https://github.com/d3/d3-selection#selection_attr) and [*selection*.style](https://github.com/d3/d3-selection#selection_style)), but not all methods are supported; for example, you must [append](https://github.com/d3/d3-selection#selection_append) elements or [bind data](https://github.com/d3/d3-selection#joining-data) before a transition starts. A [*transition*.remove](#transition_remove) operator is provided for convenient removal of elements when the transition ends. - -To compute intermediate state, transitions leverage a variety of [built-in interpolators](https://github.com/d3/d3-interpolate). [Colors](https://github.com/d3/d3-interpolate#interpolateRgb), [numbers](https://github.com/d3/d3-interpolate#interpolateNumber), and [transforms](https://github.com/d3/d3-interpolate#interpolateTransform) are automatically detected. [Strings](https://github.com/d3/d3-interpolate#interpolateString) with embedded numbers are also detected, as is common with many styles (such as padding or font sizes) and paths. To specify a custom interpolator, use [*transition*.attrTween](#transition_attrTween), [*transition*.styleTween](#transition_styleTween) or [*transition*.tween](#transition_tween). - -## Installing - -If you use NPM, `npm install d3-transition`. Otherwise, download the [latest release](https://github.com/d3/d3-transition/releases/latest). You can also load directly from [d3js.org](https://d3js.org), either as a [standalone library](https://d3js.org/d3-transition.v1.min.js) or as part of [D3](https://github.com/d3/d3). AMD, CommonJS, and vanilla environments are supported. In vanilla, a `d3` global is exported: - -```html - - - - - - - - -``` - -[Try d3-transition in your browser.](https://tonicdev.com/npm/d3-transition) - -## API Reference - -* [Selecting Elements](#selecting-elements) -* [Modifying Elements](#modifying-elements) -* [Timing](#timing) -* [Control Flow](#control-flow) -* [The Life of a Transition](#the-life-of-a-transition) - -### Selecting Elements - -Transitions are derived from [selections](https://github.com/d3/d3-selection) via [*selection*.transition](#selection_transition). You can also create a transition on the document root element using [d3.transition](#transition). - -# selection.transition([name]) [<>](https://github.com/d3/d3-transition/blob/master/src/selection/transition.js "Source") - -Returns a new transition on the given *selection* with the specified *name*. If a *name* is not specified, null is used. The new transition is only exclusive with other transitions of the same name. - -If the *name* is a [transition](#transition) instance, the returned transition has the same id and name as the specified transition. If a transition with the same id already exists on a selected element, the existing transition is returned for that element. Otherwise, the timing of the returned transition is inherited from the existing transition of the same id on the nearest ancestor of each selected element. Thus, this method can be used to synchronize a transition across multiple selections, or to re-select a transition for specific elements and modify its configuration. For example: - -```js -var t = d3.transition() - .duration(750) - .ease(d3.easeLinear); - -d3.selectAll(".apple").transition(t) - .style("fill", "red"); - -d3.selectAll(".orange").transition(t) - .style("fill", "orange"); -``` - -If the specified *transition* is not found on a selected node or its ancestors (such as if the transition [already ended](#the-life-of-a-transition)), the default timing parameters are used; however, in a future release, this will likely be changed to throw an error.

If a name is not specified, null is used. - -Interrupting a transition on an element has no effect on any transitions on any descendant elements. For example, an [axis transition](https://github.com/d3/d3-axis) consists of multiple independent, synchronized transitions on the descendants of the axis [G element](https://www.w3.org/TR/SVG/struct.html#Groups) (the tick lines, the tick labels, the domain path, *etc.*). To interrupt the axis transition, you must therefore interrupt the descendants: - -```js -selection.selectAll("*").interrupt(); -``` - -The [universal selector](https://developer.mozilla.org/en-US/docs/Web/CSS/Universal_selectors), `*`, selects all descendant elements. If you also want to interrupt the G element itself: - -```js -selection.interrupt().selectAll("*").interrupt(); -``` - -# d3.interrupt(node[, name]) [<>](https://github.com/d3/d3-transition/blob/master/src/interrupt.js "Source") - -Interrupts the active transition of the specified *name* on the specified *node*, and cancels any pending transitions with the specified *name*, if any.

If a *name* is not specified, null is used. The new transition is only exclusive with other transitions of the same name. The *name* may also be a [transition](#transition) instance; see [*selection*.transition](#selection_transition).

The new transition inherits a reference time equal to this transition’s time plus its [delay](#transition_delay) and [duration](#transition_duration). The new transition also inherits this transition’s name, duration, and [easing](#transition_ease). This method can be used to schedule a sequence of chained transitions. For example: - -```js -d3.selectAll(".apple") - .transition() // First fade to green. - .style("fill", "green") - .transition() // Then red. - .style("fill", "red") - .transition() // Wait one second. Then brown, and remove. - .delay(1000) - .style("fill", "brown") - .remove(); -``` - -The delay for each transition is relative to its previous transition. Thus, in the above example, apples will stay red for one second before the last transition to brown starts. - -# transition.selection() [<>](https://github.com/d3/d3-transition/blob/master/src/transition/selection.js "Source") - -Returns the [selection](https://github.com/d3/d3-selection#selection) corresponding to this transition. - -# d3.active(node[, name]) [<>](https://github.com/d3/d3-transition/blob/master/src/active.js "Source") - -Returns the active transition on the specified *node* with the specified *name*, if any. If no *name* is specified, null is used. Returns null if there is no such active transition on the specified node. This method is useful for creating chained transitions. For example, to initiate disco mode: - -```js -d3.selectAll("circle").transition() - .delay(function(d, i) { return i * 50; }) - .on("start", function repeat() { - d3.active(this) - .style("fill", "red") - .transition() - .style("fill", "green") - .transition() - .style("fill", "blue") - .transition() - .on("start", repeat); - }); -``` - -See [chained transitions](http://bl.ocks.org/mbostock/70d5541b547cc222aa02) for an example. - -### Modifying Elements - -After selecting elements and creating a transition with [*selection*.transition](#selection_transition), use the transition’s transformation methods to affect document content. - -# transition.attr(name, value) [<>](https://github.com/d3/d3-transition/blob/master/src/transition/attr.js "Source") - -For each selected element, assigns the [attribute tween](#transition_attrTween) for the attribute with the specified *name* to the specified target *value*.

The returned interpolator will then be invoked for each frame of the transition, in order, being passed the [eased](#transition_ease) time *t*, typically in the range [0, 1]. Lastly, the return value of the interpolator will be used to set the attribute value. The interpolator must return a string. (To remove an attribute at the start of a transition, use [*transition*.attr](#transition_attr); to remove an attribute at the end of a transition, use [*transition*.on](#transition_on) to listen for the *end* event.) - -If the specified *factory* is null, removes the previously-assigned attribute tween of the specified *name*, if any. If *factory* is not specified, returns the current interpolator factory for attribute with the specified *name*, or undefined if no such tween exists. - -For example, to interpolate the fill attribute from red to blue: - -```js -transition.attrTween("fill", function() { - return d3.interpolateRgb("red", "blue"); -}); -``` - -Or to interpolate from the current fill to blue, like [*transition*.attr](#transition_attr): - -```js -transition.attrTween("fill", function() { - return d3.interpolateRgb(this.getAttribute("fill"), "blue"); -}); -``` - -Or to apply a custom rainbow interpolator: - -```js -transition.attrTween("fill", function() { - return function(t) { - return "hsl(" + t * 360 + ",100%,50%)"; - }; -}); -``` - -This method is useful to specify a custom interpolator, such as one that understands [SVG paths](http://bl.ocks.org/mbostock/3916621). A useful technique is *data interpolation*, where [d3.interpolateObject](https://github.com/d3/d3-interpolate#interpolateObject) is used to interpolate two data values, and the resulting value is then used (say, with a [shape](https://github.com/d3/d3-shape)) to compute the new attribute value. - -# transition.style(name, value[, priority]) [<>](https://github.com/d3/d3-transition/blob/master/src/transition/style.js "Source") - -For each selected element, assigns the [style tween](#transition_styleTween) for the style with the specified *name* to the specified target *value* with the specified *priority*.

The *value* must be specified as a function. The easing function is invoked for each frame of the animation, being passed the normalized time *t* in the range [0, 1]; it must then return the eased time *tʹ* which is typically also in the range [0, 1].

To specify multiple typenames, separate typenames with spaces, such as `interrupt end` or `start.foo start.bar`. - -When a specified transition event is dispatched on a selected node, the specified *listener* will be invoked for the transitioning element, being passed the current datum `d` and index `i`, with the `this` context as the current DOM element. Listeners always see the latest datum for their element, but the index is a property of the selection and is fixed when the listener is assigned; to update the index, re-assign the listener. - -If an event listener was previously registered for the same *typename* on a selected element, the old listener is removed before the new listener is added. To remove a listener, pass null as the *listener*. To remove all listeners for a given name, pass null as the *listener* and `.foo` as the *typename*, where `foo` is the name; to remove all listeners with no name, specify `.` as the *typename*. - -If a *listener* is not specified, returns the currently-assigned listener for the specified event *typename* on the first (non-null) selected element, if any. If multiple typenames are specified, the first matching listener is returned. - -# transition.each(function) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/each.js "Source") - -Invokes the specified *function* for each selected element, passing in the current datum `d` and index `i`, with the `this` context of the current DOM element. This method can be used to invoke arbitrary code for each selected element, and is useful for creating a context to access parent and child data simultaneously. Equivalent to [*selection*.each](https://github.com/d3/d3-selection#selection_each). - -# transition.call(function[, arguments…]) [<>](https://github.com/d3/d3-selection/blob/master/src/selection/call.js "Source") - -Invokes the specified *function* exactly once, passing in this transition along with any optional *arguments*. Returns this transition. This is equivalent to invoking the function by hand but facilitates method chaining. For example, to set several attributes in a reusable function: - -```js -function color(transition, fill, stroke) { - transition - .style("fill", fill) - .style("stroke", stroke); -} -``` - -Now say: - -```js -d3.selectAll("div").transition().call(color, "red", "blue"); -``` - -This is equivalent to: - -```js -color(d3.selectAll("div").transition(), "red", "blue"); -``` - -Equivalent to [*selection*.call](https://github.com/d3/d3-selection#selection_call). - -# transition.empty() [<>](https://github.com/d3/d3-selection/blob/master/src/selection/empty.js "Source") - -Returns true if this transition contains no (non-null) elements. Equivalent to [*selection*.empty](https://github.com/d3/d3-selection#selection_empty). - -# transition.nodes() [<>](https://github.com/d3/d3-selection/blob/master/src/selection/nodes.js "Source") - -Returns an array of all (non-null) elements in this transition. Equivalent to [*selection*.nodes](https://github.com/d3/d3-selection#selection_nodes). - -# transition.node() [<>](https://github.com/d3/d3-selection/blob/master/src/selection/node.js "Source") - -Returns the first (non-null) element in this transition. If the transition is empty, returns null. Equivalent to [*selection*.node](https://github.com/d3/d3-selection#selection_node). - -# transition.size() [<>](https://github.com/d3/d3-selection/blob/master/src/selection/size.js "Source") - -Returns the total number of elements in this transition. Equivalent to [*selection*.size](https://github.com/d3/d3-selection#selection_size). - -### The Life of a Transition - -Immediately after creating a transition, such as by [*selection*.transition](#selection_transition) or [*transition*.transition](#transition_transition), you may configure the transition using methods such as [*transition*.delay](#transition_delay), [*transition*.duration](#transition_duration), [*transition*.attr](#transition_attr) and [*transition*.style](#transition_style). Methods that specify target values (such as *transition*.attr) are evaluated synchronously; however, methods that require the starting value for interpolation, such as [*transition*.attrTween](#transition_attrTween) and [*transition*.styleTween](#transition_styleTween), must be deferred until the transition starts. - -Shortly after creation, either at the end of the current frame or during the next frame, the transition is scheduled. At this point, the delay and `start` event listeners may no longer be changed; attempting to do so throws an error with the message “too late: already scheduled” (or if the transition has ended, “transition not found”). - -When the transition subsequently starts, it interrupts the active transition of the same name on the same element, if any, dispatching an `interrupt` event to registered listeners. (Note that interrupts happen on start, not creation, and thus even a zero-delay transition will not immediately interrupt the active transition: the old transition is given a final frame. Use [*selection*.interrupt](#selection_interrupt) to interrupt immediately.) The starting transition also cancels any pending transitions of the same name on the same element that were created before the starting transition. The transition then dispatches a `start` event to registered listeners. This is the last moment at which the transition may be modified: the transition’s timing, tweens, and listeners may not be changed when it is running; attempting to do so throws an error with the message “too late: already running” (or if the transition has ended, “transition not found”). The transition initializes its tweens immediately after starting. - -During the frame the transition starts, but *after* all transitions starting this frame have been started, the transition invokes its tweens for the first time. Batching tween initialization, which typically involves reading from the DOM, improves performance by avoiding interleaved DOM reads and writes. - -For each frame that a transition is active, it invokes its tweens with an [eased](#transition_ease) *t*-value ranging from 0 to 1. Within each frame, the transition invokes its tweens in the order they were registered. - -When a transition ends, it invokes its tweens a final time with a (non-eased) *t*-value of 1. It then dispatches an `end` event to registered listeners. This is the last moment at which the transition may be inspected: after ending, the transition is deleted from the element, and its configuration is destroyed. (A transition’s configuration is also destroyed on interrupt or cancel.) Attempting to inspect a transition after it is destroyed throws an error with the message “transition not found”. diff --git a/node_modules/d3-transition/dist/d3-transition.js b/node_modules/d3-transition/dist/d3-transition.js deleted file mode 100644 index 39b1db4c773ada25bcf5dd2360bdd4b705a4cc0e..0000000000000000000000000000000000000000 --- a/node_modules/d3-transition/dist/d3-transition.js +++ /dev/null @@ -1,880 +0,0 @@ -// https://d3js.org/d3-transition/ v1.3.2 Copyright 2019 Mike Bostock -(function (global, factory) { -typeof exports === 'object' && typeof module !== 'undefined' ?

It is easy to learn due to direct manipulation: click-and-drag to pan (translate), spin the wheel to zoom (scale), or use touch. Panning and zooming are widely used in web-based mapping, but can also be used with visualizations such as time-series and scatterplots. - -The zoom behavior implemented by d3-zoom is a convenient but flexible abstraction for enabling pan-and-zoom on [selections](https://github.com/d3/d3-selection). It handles a surprising variety of [input events](#api-reference ) and browser quirks. The zoom behavior is agnostic about the DOM, so you can use it with SVG, HTML or Canvas. - -[Canvas Zooming](https://bl.ocks.org/mbostock/d1f7b58631e71fbf9c568345ee04a60e)[SVG Zooming](https://bl.ocks.org/mbostock/4e3925cdc804db257a86fdef3a032a45) - -The zoom behavior is also designed to work with [d3-scale](https://github.com/d3/d3-scale) and [d3-axis](https://github.com/d3/d3-axis); see [*transform*.rescaleX](#transform_rescaleX) and [*transform*.rescaleY](#transform_rescaleY). You can also restrict zooming using [*zoom*.scaleExtent](#zoom_scaleExtent) and panning using [*zoom*.translateExtent](#zoom_translateExtent). - -[Axis Zooming](https://bl.ocks.org/mbostock/db6b4335bf1662b413e7968910104f0f) - -The zoom behavior can be combined with other behaviors, such as [d3-drag](https://github.com/d3/d3-drag) for dragging, and [d3-brush](https://github.com/d3/d3-brush) for focus + context. - -[Drag & Zoom II](https://bl.ocks.org/mbostock/3127661b6f13f9316be745e77fdfb084)[Brush & Zoom](https://bl.ocks.org/mbostock/34f08d5e11952a80609169b7917d4172) - -The zoom behavior can be controlled programmatically using [*zoom*.transform](#zoom_transform), allowing you to implement user interface controls which drive the display or to stage animated tours through your data. Smooth zoom transitions are based on [“Smooth and efficient zooming and panning”](http://www.win.tue.nl/~vanwijk/zoompan.pdf) by Jarke J. van Wijk and Wim A.A.

Otherwise, download the [latest release](https://github.com/d3/d3-zoom/releases/latest). You can also load directly from [d3js.org](https://d3js.org), either as a [standalone library](https://d3js.org/d3-zoom.v1.min.js) or as part of [D3 4.0](https://github.com/d3/d3).

The returned behavior, [*zoom*](#_drag), is both an object and a function, and is typically applied to selected elements via [*selection*.call](https://github.com/d3/d3-selection#selection_call). - -# zoom(selection) [<>](https://github.com/d3/d3-zoom/blob/master/src/zoom.js "Source") - -Applies this zoom behavior to the specified [*selection*](https://github.com/d3/d3-selection), binding the necessary event listeners to allow panning and zooming, and initializing the [zoom transform](#zoom-transforms) on each selected element to the identity transform if not already defined. This function is typically not invoked directly, and is instead invoked via [*selection*.call](https://github.com/d3/d3-selection#selection_call). For example, to instantiate a zoom behavior and apply it to a selection: - -```js -selection.call(d3.zoom().on("zoom", zoomed)); -``` - -Internally, the zoom behavior uses [*selection*.on](https://github.com/d3/d3-selection#selection_on) to bind the necessary event listeners for zooming. The listeners use the name `.zoom`, so you can subsequently unbind the zoom behavior as follows: - -```js -selection.on(".zoom", null); -``` - -To disable just wheel-driven zooming (say to not interfere with native scrolling), you can remove the zoom behavior’s wheel event listener after applying the zoom behavior to the selection: - -```js -selection - .call(zoom) - .on("wheel.zoom", null); -``` - -Alternatively, use [*zoom*.filter](#zoom_filter) for greater control over which events can initiate zoom gestures. - -Applying the zoom behavior also sets the [-webkit-tap-highlight-color](https://developer.apple.com/library/mac/documentation/AppleApplications/Reference/SafariWebContent/AdjustingtheTextSize/AdjustingtheTextSize.html#//apple_ref/doc/uid/TP40006510-SW5) style to transparent, disabling the tap highlight on iOS. If you want a different tap highlight color, remove or re-apply this style after applying the drag behavior. - -# zoom.transform(selection, transform[, point]) [<>](https://github.com/d3/d3-zoom/blob/master/src/zoom.js "Source") - -If *selection* is a selection, sets the [current zoom transform](#zoomTransform) of the selected elements to the specified *transform*, instantaneously emitting start, zoom and end [events](#zoom-events). If *selection* is a transition, defines a “zoom” tween to the specified *transform* using [d3.interpolateZoom](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateZoom), emitting a start event when the transition starts, zoom events for each tick of the transition, and then an end event when the transition ends (or is interrupted). The transition will attempt to minimize the visual movement around the specified *point*; if the *point* is not specified, it defaults to the center of the viewport [extent](#zoom_extent). The *transform* may be specified either as a [zoom transform](#zoom-transforms) or as a function that returns a zoom transform; similarly, the *point* may be specified either as a two-element array [*x*, *y*] or a function that returns such an array.

If *extent* is not specified, returns the current scale extent, which defaults to [0, ∞]. The scale extent restricts zooming in and out. It is enforced on interaction and when using [*zoom*.scaleBy](#zoom_scaleBy), [*zoom*.scaleTo](#zoom_scaleTo) and [*zoom*.translateBy](#zoom_translateBy); however, it is not enforced when using [*zoom*.transform](#zoom_transform) to set the transform explicitly. - -If the user tries to zoom by wheeling when already at the corresponding limit of the scale extent, the wheel events will be ignored and not initiate a zoom gesture. This allows the user to scroll down past a zoomable area after zooming in, or to scroll up after zooming out.

If *extent* is not specified, returns the current translate extent, which defaults to [[-∞, -∞], [+∞, +∞]]. The translate extent restricts panning, and may cause translation on zoom out. It is enforced on interaction and when using [*zoom*.scaleBy](#zoom_scaleBy), [*zoom*.scaleTo](#zoom_scaleTo) and [*zoom*.translateBy](#zoom_translateBy); however, it is not enforced when using [*zoom*.transform](#zoom_transform) to set the transform explicitly. - -# zoom.clickDistance([distance]) [<>](https://github.com/d3/d3-zoom/blob/master/src/zoom.js "Source") - -If *distance* is specified, sets the maximum distance that the mouse can move between mousedown and mouseup that will trigger a subsequent click event. If at any point between mousedown and mouseup the mouse is greater than or equal to *distance* from its position on mousedown, the click event following mouseup will be suppressed. If *distance* is not specified, returns the current distance threshold, which defaults to zero. The distance threshold is measured in client coordinates ([*event*.clientX](https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/clientX) and [*event*.clientY](https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/clientY)). - -# zoom.duration([duration]) [<>](https://github.com/d3/d3-zoom/blob/master/src/zoom.js "Source") - -If *duration* is specified, sets the duration for zoom transitions on double-click and double-tap to the specified number of milliseconds and returns the zoom behavior. If *duration* is not specified, returns the current duration, which defaults to 250 milliseconds. If the duration is not greater than zero, double-click and -tap trigger instantaneous changes to the zoom transform rather than initiating smooth transitions. - -To disable double-click and double-tap transitions, you can remove the zoom behavior’s dblclick event listener after applying the zoom behavior to the selection: - -```js -selection - .call(zoom) - .on("dblclick.zoom", null); -``` - -# zoom.interpolate([interpolate]) [<>](https://github.com/d3/d3-zoom/blob/master/src/zoom.js "Source") - -If *interpolate* is specified, sets the interpolation factory for zoom transitions to the specified function. If *interpolate* is not specified, returns the current interpolation factory, which defaults to [d3.interpolateZoom](https://github.com/d3/d3-interpolate#interpolateZoom) to implement smooth zooming. To apply direct interpolation between two views, try [d3.interpolate](https://github.com/d3/d3-interpolate#interpolate) instead. - -# zoom.on(typenames[, listener]) [<>](https://github.com/d3/d3-zoom/blob/master/src/zoom.js "Source") - -If *listener* is specified, sets the event *listener* for the specified *typenames* and returns the zoom behavior. If an event listener was already registered for the same type and name, the existing listener is removed before the new listener is added. If *listener* is null, removes the current event listeners for the specified *typenames*, if any. If *listener* is not specified, returns the first currently-assigned listener matching the specified *typenames*, if any. When a specified event is dispatched, each *listener* will be invoked with the same context and arguments as [*selection*.on](https://github.com/d3/d3-selection#selection_on) listeners: the current datum `d` and index `i`, with the `this` context as the current DOM element. - -The *typenames* is a string containing one or more *typename* separated by whitespace. Each *typename* is a *type*, optionally followed by a period (`.`) and a *name*, such as `zoom.foo` and `zoom.bar`; the name allows multiple listeners to be registered for the same *type*. The *type* must be one of the following: - -* `start` - after zooming begins (such as on mousedown). -* `zoom` - after a change to the zoom transform (such as on mousemove). -* `end` - after zooming ends (such as on mouseup ). - -See [*dispatch*.on](https://github.com/d3/d3-dispatch#dispatch_on) for more. - -### Zoom Events - -When a [zoom event listener](#zoom_on) is invoked, [d3.event](https://github.com/d3/d3-selection#event) is set to the current zoom event. The *event* object exposes several fields: - -* *event*.target - the associated [zoom behavior](#zoom). -* *event*.type - the string “start”, “zoom” or “end”; see [*zoom*.on](#zoom_on). -* *event*.transform - the current [zoom transform](#zoom-transforms). -* *event*.sourceEvent - the underlying input event, such as mousemove or touchmove. - -### Zoom Transforms - -The zoom behavior stores the zoom state on the element to which the zoom behavior was [applied](#_zoom), not on the zoom behavior itself. This is because the zoom behavior can be applied to many elements simultaneously, and each element can be zoomed independently. The zoom state can change either on user interaction or programmatically via [*zoom*.transform](#zoom_transform). - -To retrieve the zoom state, use *event*.transform on the current [zoom event](#zoom-events) within a zoom event listener (see [*zoom*.on](#zoom_on)), or use [d3.zoomTransform](#zoomTransform) for a given node. The latter is particularly useful for modifying the zoom state programmatically, say to implement buttons for zooming in and out. - -# d3.zoomTransform(node) [<>](https://github.com/d3/d3-zoom/blob/master/src/transform.js "Source") - -Returns the current transform for the specified *node*. Note that *node* should typically be a DOM element, not a *selection*. (A selection may consist of multiple nodes, in different states, and this function only returns a single transform.) If you have a selection, call [*selection*.node](https://github.com/d3/d3-selection#selection_node) first: - -```js -var transform = d3.zoomTransform(selection.node()); -``` - -In the context of an [event listener](https://github.com/d3/d3-selection#selection_on), the *node* is typically the element that received the input event (which should be equal to [*event*.transform](#zoom-events)), *this*: - -```js -var transform = d3.zoomTransform(this); -``` - -Internally, an element’s transform is stored as *element*.\_\_zoom; however, you should use this method rather than accessing it directly. If the given *node* has no defined transform, returns the transform of the closest ancestor, or if none exists, the [identity transformation](#zoomIdentity). The returned transform represents a two-dimensional [transformation matrix](https://en.wikipedia.org/wiki/Transformation_matrix#Affine_transformations) of the form: - -*k* 0 *tx* -
0 *k* *ty* -
0 0 1 - -(This matrix is capable of representing only scale and translation; a future release may also allow rotation, though this would probably not be a backwards-compatible change.) The position ⟨*x*,*y*⟩ is transformed to ⟨*xk* + *tx*,*yk* + *ty*⟩. The transform object exposes the following properties: - -* *transform*.x - the translation amount *tx* along the *x*-axis. -* *transform*.y - the translation amount *ty* along the *y*-axis. -* *transform*.k - the scale factor *k*. - -These properties should be considered read-only; instead of mutating a transform, use [*transform*.scale](#transform_scale) and [*transform*.translate](#transform_translate) to derive a new transform. Also see [*zoom*.scaleBy](#zoom_scaleBy), [*zoom*.scaleTo](#zoom_scaleTo) and [*zoom*.translateBy](#zoom_translateBy) for convenience methods on the zoom behavior.

For minor and patch changes, please see the [release notes](https://github.com/d3/d3/releases).* - -D3 5.0 introduces only a few non-backwards-compatible changes. - -D3 now uses [Promises](https://developer.mozilla.org/docs/Web/JavaScript/Guide/Using_promises) instead of asynchronous callbacks to load data. Promises simplify the structure of asynchronous code, especially in modern browsers that support [async and await](https://javascript.info/async-await). (See this [introduction to promises](https://observablehq.com/@observablehq/introduction-to-promises) on [Observable](https://observablehq.com).) For example, to load a CSV file in v4, you might say: - -```js -d3.csv("file.csv", function(error, data) { - if (error) throw error; - console.log(data); -}); -``` - -In v5, using promises: - -```js -d3.csv("file.csv").then(function(data) { - console.log(data); -}); -``` - -Note that you don’t need to rethrow the error—the promise will reject automatically, and you can *promise*.catch if desired. Using await, the code is even simpler: - -```js -const data = await d3.csv("file.csv"); -console.log(data); -``` - -With the adoption of promises, D3 now uses the [Fetch API](https://fetch.spec.whatwg.org/) instead of [XMLHttpRequest](https://developer.mozilla.org/docs/Web/API/XMLHttpRequest): the [d3-request](https://github.com/d3/d3-request) module has been replaced by [d3-fetch](https://github.com/d3/d3-fetch). Fetch supports many powerful new features, such as [streaming responses](https://observablehq.com/@mbostock/streaming-shapefiles). D3 5.0 also deprecates and removes the [d3-queue](https://github.com/d3/d3-queue) module. Use [Promise.all](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise/all) to run a batch of asynchronous tasks in parallel, or a helper library such as [p-queue](https://github.com/sindresorhus/p-queue) to [control concurrency](https://observablehq.com/@mbostock/hello-p-queue). - -D3 no longer provides the d3.schemeCategory20* categorical color schemes. These twenty-color schemes were flawed because their grouped design could falsely imply relationships in the data: a shared hue can imply that the encoded data are part of a group (a super-category), while relative lightness can imply order. Instead, D3 now includes [d3-scale-chromatic](https://github.com/d3/d3-scale-chromatic), which implements excellent schemes from ColorBrewer, including [categorical](https://github.com/d3/d3-scale-chromatic/blob/master/README.md#categorical), [diverging](https://github.com/d3/d3-scale-chromatic/blob/master/README.md#diverging), [sequential single-hue](https://github.com/d3/d3-scale-chromatic/blob/master/README.md#sequential-single-hue) and [sequential multi-hue](https://github.com/d3/d3-scale-chromatic/blob/master/README.md#sequential-multi-hue) schemes. These schemes are available in both discrete and continuous variants. - -D3 now provides implementations of [marching squares](https://observablehq.com/@d3/contours) and [density estimation](https://observablehq.com/@d3/density-contours) via [d3-contour](https://github.com/d3/d3-contour)! There are two new [d3-selection](https://github.com/d3/d3-selection) methods: [*selection*.clone](https://github.com/d3/d3-selection/blob/master/README.md#selection_clone) for inserting clones of the selected nodes, and [d3.create](https://github.com/d3/d3-selection/blob/master/README.md#create) for creating detached elements. [Geographic projections](https://github.com/d3/d3-geo) now support [*projection*.angle](https://github.com/d3/d3-geo/blob/master/README.md#projection_angle), which has enabled several fantastic new [polyhedral projections](https://github.com/d3/d3-geo-polygon) by Philippe Rivière. - -Lastly, D3’s [package.json](https://github.com/d3/d3/blob/master/package.json) no longer pins exact versions of the dependent D3 modules. This fixes an issue with [duplicate installs](https://github.com/d3/d3/issues/3256) of D3 modules. - -# Changes in D3 4.0 - -[Released June 28, 2016.](https://github.com/d3/d3/releases/tag/v4.0.0) - -D3 4.0 is modular. Instead of one library, D3 is now [many small libraries](#table-of-contents) that are designed to work together. You can pick and choose which parts to use as you see fit. Each library is maintained in its own repository, allowing decentralized ownership and independent release cycles. The default bundle combines about thirty of these microlibraries. - -```html - -``` - -As before, you can load optional plugins on top of the default bundle, such as [ColorBrewer scales](https://github.com/d3/d3-scale-chromatic): - -```html - - -``` - -You are not required to use the default bundle! If you’re just using [d3-selection](https://github.com/d3/d3-selection), use it as a standalone library. Like the default bundle, you can load D3 microlibraries using vanilla script tags or RequireJS (great for HTTP/2!): - -```html - -``` - -You can also `cat` D3 microlibraries into a custom bundle, or use tools such as [Webpack](https://webpack.github.io/) and [Rollup](http://rollupjs.org/) to create [optimized bundles](https://bl.ocks.org/mbostock/bb09af4c39c79cffcde4). Custom bundles are great for applications that use a subset of D3’s features; for example, a React chart library might use D3 for scales and shapes, and React to manipulate the DOM. The D3 microlibraries are written as [ES6 modules](http://www.2ality.com/2014/09/es6-modules-final.html), and Rollup lets you pick at the symbol level to produce smaller bundles. - -Small files are nice, but modularity is also about making D3 more *fun*. Microlibraries are easier to understand, develop and test. They make it easier for new people to get involved and contribute. They reduce the distinction between a “core module” and a “plugin”, and increase the pace of development in D3 features. - -If you don’t care about modularity, you can mostly ignore this change and keep using the default bundle. However, there is one unavoidable consequence of adopting ES6 modules: every symbol in D3 4.0 now shares a flat namespace rather than the nested one of D3 3.x. For example, d3.scale.linear is now d3.scaleLinear, and d3.layout.treemap is now d3.treemap. The adoption of ES6 modules also means that D3 is now written exclusively in [strict mode](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Strict_mode) and has better readability. And there have been many other significant improvements to D3’s features! (Nearly all of the code from D3 3.x has been rewritten.) These changes are covered below. - -### Other Global Changes - -The default [UMD bundle](https://github.com/umdjs/umd) is now [anonymous](https://github.com/requirejs/requirejs/wiki/Updating-existing-libraries#register-as-an-anonymous-module-). No `d3` global is exported if AMD or CommonJS is detected. In a vanilla environment, the D3 microlibraries share the `d3` global, even if you load them independently; thus, code you write is the same whether or not you use the default bundle. (See [Let’s Make a (D3) Plugin](https://bost.ocks.org/mike/d3-plugin/) for more.) The generated bundle is no longer stored in the Git repository; Bower has been repointed to [d3-bower](https://github.com/mbostock-bower/d3-bower), and you can find the generated files on [npm](https://unpkg.com/d3) or attached to the [latest release](https://github.com/d3/d3/releases/latest). The non-minified default bundle is no longer mangled, making it more readable and preserving inline comments. - -To the consternation of some users, 3.x employed Unicode variable names such as λ, φ, τ and π for a concise representation of mathematical operations. A downside of this approach was that a SyntaxError would occur if you loaded the non-minified D3 using ISO-8859-1 instead of UTF-8. 3.x also used Unicode string literals, such as the SI-prefix µ for 1e-6. 4.0 uses only ASCII variable names and ASCII string literals (see [rollup-plugin-ascii](https://github.com/mbostock/rollup-plugin-ascii)), avoiding encoding problems. - -### Table of Contents - -* [Arrays](#arrays-d3-array) -* [Axes](#axes-d3-axis) -* [Brushes](#brushes-d3-brush) -* [Chords](#chords-d3-chord) -* [Collections](#collections-d3-collection) -* [Colors](#colors-d3-color) -* [Dispatches](#dispatches-d3-dispatch) -* [Dragging](#dragging-d3-drag) -* [Delimiter-Separated Values](#delimiter-separated-values-d3-dsv) -* [Easings](#easings-d3-ease) -* [Forces](#forces-d3-force) -* [Number Formats](#number-formats-d3-format) -* [Geographies](#geographies-d3-geo) -* [Hierarchies](#hierarchies-d3-hierarchy) -* [Internals](#internals) -* [Interpolators](#interpolators-d3-interpolate) -* [Paths](#paths-d3-path) -* [Polygons](#polygons-d3-polygon) -* [Quadtrees](#quadtrees-d3-quadtree) -* [Queues](#queues-d3-queue) -* [Random Numbers](#random-numbers-d3-random) -* [Requests](#requests-d3-request) -* [Scales](#scales-d3-scale) -* [Selections](#selections-d3-selection) -* [Shapes](#shapes-d3-shape) -* [Time Formats](#time-formats-d3-time-format) -* [Time Intervals](#time-intervals-d3-time) -* [Timers](#timers-d3-timer) -* [Transitions](#transitions-d3-transition) -* [Voronoi Diagrams](#voronoi-diagrams-d3-voronoi) -* [Zooming](#zooming-d3-zoom) - -## [Arrays (d3-array)](https://github.com/d3/d3-array/blob/master/README.md) - -The new [d3.scan](https://github.com/d3/d3-array/blob/master/README.md#scan) method performs a linear scan of an array, returning the index of the least element according to the specified comparator. This is similar to [d3.min](https://github.com/d3/d3-array/blob/master/README.md#min) and [d3.max](https://github.com/d3/d3-array/blob/master/README.md#max), except you can use it to find the position of an extreme element, rather than just calculate an extreme value. - -```js -var data = [ - {name: "Alice", value: 2}, - {name: "Bob", value: 3}, - {name: "Carol", value: 1}, - {name: "Dwayne", value: 5} -]; - -var i = d3.scan(data, function(a, b) { return a.value - b.value; }); // 2 -data[i]; // {name: "Carol", value: 1} -``` - -The new [d3.ticks](https://github.com/d3/d3-array/blob/master/README.md#ticks) and [d3.tickStep](https://github.com/d3/d3-array/blob/master/README.md#tickStep) methods are useful for generating human-readable numeric ticks. These methods are a low-level alternative to [*continuous*.ticks](https://github.com/d3/d3-scale/blob/master/README.md#continuous_ticks) from [d3-scale](https://github.com/d3/d3-scale). The new implementation is also more accurate, returning the optimal number of ticks as measured by relative error. - -```js -var ticks = d3.ticks(0, 10, 5); // [0, 2, 4, 6, 8, 10] -``` - -The [d3.range](https://github.com/d3/d3-array/blob/master/README.md#range) method no longer makes an elaborate attempt to avoid floating-point error when *step* is not an integer. The returned values are strictly defined as *start* + *i* \* *step*, where *i* is an integer. (Learn more about [floating point math](http://0.30000000000000004.com/).) d3.range returns the empty array for infinite ranges, rather than throwing an error. - -The method signature for optional accessors has been changed to be more consistent with array methods such as [*array*.forEach](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/forEach): the accessor is passed the current element (*d*), the index (*i*), and the array (*data*), with *this* as undefined. This affects [d3.min](https://github.com/d3/d3-array/blob/master/README.md#min), [d3.max](https://github.com/d3/d3-array/blob/master/README.md#max), [d3.extent](https://github.com/d3/d3-array/blob/master/README.md#extent), [d3.sum](https://github.com/d3/d3-array/blob/master/README.md#sum), [d3.mean](https://github.com/d3/d3-array/blob/master/README.md#mean), [d3.median](https://github.com/d3/d3-array/blob/master/README.md#median), [d3.quantile](https://github.com/d3/d3-array/blob/master/README.md#quantile), [d3.variance](https://github.com/d3/d3-array/blob/master/README.md#variance) and [d3.deviation](https://github.com/d3/d3-array/blob/master/README.md#deviation). The [d3.quantile](https://github.com/d3/d3-array/blob/master/README.md#quantile) method previously did not take an accessor. Some methods with optional arguments now treat those arguments as missing if they are null or undefined, rather than strictly checking arguments.length. - -The new [d3.histogram](https://github.com/d3/d3-array/blob/master/README.md#histograms) API replaces d3.layout.histogram. Rather than exposing *bin*.x and *bin*.dx on each returned bin, the histogram exposes *bin*.x0 and *bin*.x1, guaranteeing that *bin*.x0 is exactly equal to *bin*.x1 on the preceding bin. The “frequency” and “probability” modes are no longer supported; each bin is simply an array of elements from the input data, so *bin*.length is equal to D3 3.x’s *bin*.y in frequency mode. To compute a probability distribution, divide the number of elements in each bin by the total number of elements. - -The *histogram*.range method has been renamed [*histogram*.domain](https://github.com/d3/d3-array/blob/master/README.md#histogram_domain) for consistency with scales. The *histogram*.bins method has been renamed [*histogram*.thresholds](https://github.com/d3/d3-array/blob/master/README.md#histogram_thresholds), and no longer accepts an upper value: *n* thresholds will produce *n* + 1 bins. If you specify a desired number of bins rather than thresholds, d3.histogram now uses [d3.ticks](https://github.com/d3/d3-array/blob/master/README.md#ticks) to compute nice bin thresholds. In addition to the default Sturges’ formula, D3 now implements the [Freedman-Diaconis rule](https://github.com/d3/d3-array/blob/master/README.md#thresholdFreedmanDiaconis) and [Scott’s normal reference rule](https://github.com/d3/d3-array/blob/master/README.md#thresholdScott). - -## [Axes (d3-axis)](https://github.com/d3/d3-axis/blob/master/README.md) - -To render axes properly in D3 3.x, you needed to style them: - -```html - - -``` - -If you didn’t, you saw this: - - - -D3 4.0 provides default styles and shorter syntax. In place of d3.svg.axis and *axis*.orient, D3 4.0 now provides four constructors for each orientation: [d3.axisTop](https://github.com/d3/d3-axis/blob/master/README.md#axisTop), [d3.axisRight](https://github.com/d3/d3-axis/blob/master/README.md#axisRight), [d3.axisBottom](https://github.com/d3/d3-axis/blob/master/README.md#axisBottom), [d3.axisLeft](https://github.com/d3/d3-axis/blob/master/README.md#axisLeft). These constructors accept a scale, so you can reduce all of the above to: - -```html - -``` - -And get this: - - - -As before, you can customize the axis appearance either by applying stylesheets or by modifying the axis elements. The default appearance has been changed slightly to offset the axis by a half-pixel; this fixes a crisp-edges rendering issue on Safari where the axis would be drawn two-pixels thick. - -There’s now an [*axis*.tickArguments](https://github.com/d3/d3-axis/blob/master/README.md#axis_tickArguments) method, as an alternative to [*axis*.ticks](https://github.com/d3/d3-axis/blob/master/README.md#axis_ticks) that also allows the axis tick arguments to be inspected. The [*axis*.tickSize](https://github.com/d3/d3-axis/blob/master/README.md#axis_tickSize) method has been changed to only allow a single argument when setting the tick size. The *axis*.innerTickSize and *axis*.outerTickSize methods have been renamed [*axis*.tickSizeInner](https://github.com/d3/d3-axis/blob/master/README.md#axis_tickSizeInner) and [*axis*.tickSizeOuter](https://github.com/d3/d3-axis/blob/master/README.md#axis_tickSizeOuter), respectively. - -## [Brushes (d3-brush)](https://github.com/d3/d3-brush/blob/master/README.md) - -Replacing d3.svg.brush, there are now three classes of brush for brushing along the *x*-dimension, the *y*-dimension, or both: [d3.brushX](https://github.com/d3/d3-brush/blob/master/README.md#brushX), [d3.brushY](https://github.com/d3/d3-brush/blob/master/README.md#brushY), [d3.brush](https://github.com/d3/d3-brush/blob/master/README.md#brush). Brushes are no longer dependent on [scales](#scales-d3-scale); instead, each brush defines a selection in screen coordinates. This selection can be [inverted](https://github.com/d3/d3-scale/blob/master/README.md#continuous_invert) if you want to compute the corresponding data domain. And rather than rely on the scales’ ranges to determine the brushable area, there is now a [*brush*.extent](https://github.com/d3/d3-brush/blob/master/README.md#brush_extent) method for setting it. If you do not set the brush extent, it defaults to the full extent of the owner SVG element. The *brush*.clamp method has also been eliminated; brushing is always restricted to the brushable area defined by the brush extent. - -Brushes no longer store the active brush selection (*i.e.*, the highlighted region; the brush’s position) internally. The brush’s position is now stored on any elements to which the brush has been applied. The brush’s position is available as *event*.selection within a brush event or by calling [d3.brushSelection](https://github.com/d3/d3-brush/blob/master/README.md#brushSelection) on a given *element*. To move the brush programmatically, use [*brush*.move](https://github.com/d3/d3-brush/blob/master/README.md#brush_move) with a given [selection](#selections-d3-selection) or [transition](#transitions-d3-transition); see the [brush snapping example](https://bl.ocks.org/mbostock/6232537). The *brush*.event method has been removed. - -Brush interaction has been improved. By default, brushes now ignore right-clicks intended for the context menu; you can change this behavior using [*brush*.filter](https://github.com/d3/d3-brush/blob/master/README.md#brush_filter). Brushes also ignore emulated mouse events on iOS. Holding down SHIFT (⇧) while brushing locks the *x*- or *y*-position of the brush. Holding down META (⌘) while clicking and dragging starts a new selection, rather than translating the existing selection. - -The default appearance of the brush has also been improved and slightly simplified. Previously it was necessary to apply styles to the brush to give it a reasonable appearance, such as: - -```css -.brush .extent { - stroke: #fff; - fill-opacity: .125; - shape-rendering: crispEdges; -} -``` - -These styles are now applied by default as attributes; if you want to customize the brush appearance, you can still apply external styles or modify the brush elements. (D3 4.0 features a similar improvement to [axes](#axes-d3-axis).) A new [*brush*.handleSize](https://github.com/d3/d3-brush/blob/master/README.md#brush_handleSize) method lets you override the brush handle size; it defaults to six pixels. - -The brush now consumes handled events, making it easier to combine with other interactive behaviors such as [dragging](#dragging-d3-drag) and [zooming](#zooming-d3-zoom). The *brushstart* and *brushend* events have been renamed to *start* and *end*, respectively. The brush event no longer reports a *event*.mode to distinguish between resizing and dragging the brush. - -## [Chords (d3-chord)](https://github.com/d3/d3-chord/blob/master/README.md) - -Pursuant to the great namespace flattening: - -* d3.layout.chord ↦ [d3.chord](https://github.com/d3/d3-chord/blob/master/README.md#chord) -* d3.svg.chord ↦ [d3.ribbon](https://github.com/d3/d3-chord/blob/master/README.md#ribbon) - -For consistency with [*arc*.padAngle](https://github.com/d3/d3-shape/blob/master/README.md#arc_padAngle), *chord*.padding has also been renamed to [*ribbon*.padAngle](https://github.com/d3/d3-chord/blob/master/README.md#ribbon_padAngle). A new [*ribbon*.context](https://github.com/d3/d3-chord/blob/master/README.md#ribbon_context) method lets you render chord diagrams to Canvas! See also [d3-path](#paths-d3-path). - -## [Collections (d3-collection)](https://github.com/d3/d3-collection/blob/master/README.md) - -The [d3.set](https://github.com/d3/d3-collection/blob/master/README.md#set) constructor now accepts an existing set for making a copy. If you pass an array to d3.set, you can also pass a value accessor. This accessor takes the standard arguments: the current element (*d*), the index (*i*), and the array (*data*), with *this* undefined. For example: - -```js -var yields = [ - {yield: 22.13333, variety: "Manchuria", year: 1932, site: "Grand Rapids"}, - {yield: 26.76667, variety: "Peatland", year: 1932, site: "Grand Rapids"}, - {yield: 28.10000, variety: "No. 462", year: 1931, site: "Duluth"}, - {yield: 38.50000, variety: "Svansota", year: 1932, site: "Waseca"}, - {yield: 40.46667, variety: "Svansota", year: 1931, site: "Crookston"}, - {yield: 36.03333, variety: "Peatland", year: 1932, site: "Waseca"}, - {yield: 34.46667, variety: "Wisconsin No. 38", year: 1931, site: "Grand Rapids"} -]; - -var sites = d3.set(yields, function(d) { return d.site; }); // Grand Rapids, Duluth, Waseca, Crookston -``` - -The [d3.map](https://github.com/d3/d3-collection/blob/master/README.md#map) constructor also follows the standard array accessor argument pattern. - -The *map*.forEach and *set*.forEach methods have been renamed to [*map*.each](https://github.com/d3/d3-collection/blob/master/README.md#map_each) and [*set*.each](https://github.com/d3/d3-collection/blob/master/README.md#set_each) respectively. The order of arguments for *map*.each has also been changed to *value*, *key* and *map*, while the order of arguments for *set*.each is now *value*, *value* and *set*. This is closer to ES6 [*map*.forEach](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map/forEach) and [*set*.forEach](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set/forEach). Also like ES6 Map and Set, *map*.set and *set*.add now return the current collection (rather than the added value) to facilitate method chaining. New [*map*.clear](https://github.com/d3/d3-collection/blob/master/README.md#map_clear) and [*set*.clear](https://github.com/d3/d3-collection/blob/master/README.md#set_clear) methods can be used to empty collections. - -The [*nest*.map](https://github.com/d3/d3-collection/blob/master/README.md#nest_map) method now always returns a d3.map instance. For a plain object, use [*nest*.object](https://github.com/d3/d3-collection/blob/master/README.md#nest_object) instead. When used in conjunction with [*nest*.rollup](https://github.com/d3/d3-collection/blob/master/README.md#nest_rollup), [*nest*.entries](https://github.com/d3/d3-collection/blob/master/README.md#nest_entries) now returns {key, value} objects for the leaf entries, instead of {key, values}. This makes *nest*.rollup easier to use in conjunction with [hierarchies](#hierarchies-d3-hierarchy), as in this [Nest Treemap example](https://bl.ocks.org/mbostock/2838bf53e0e65f369f476afd653663a2). - -## [Colors (d3-color)](https://github.com/d3/d3-color/blob/master/README.md) - -All colors now have opacity exposed as *color*.opacity, which is a number in [0, 1]. You can pass an optional opacity argument to the color space constructors [d3.rgb](https://github.com/d3/d3-color/blob/master/README.md#rgb), [d3.hsl](https://github.com/d3/d3-color/blob/master/README.md#hsl), [d3.lab](https://github.com/d3/d3-color/blob/master/README.md#lab), [d3.hcl](https://github.com/d3/d3-color/blob/master/README.md#hcl) or [d3.cubehelix](https://github.com/d3/d3-color/blob/master/README.md#cubehelix). - -You can now parse rgba(…) and hsla(…) CSS color specifiers or the string “transparent” using [d3.color](https://github.com/d3/d3-color/blob/master/README.md#color). The “transparent” color is defined as an RGB color with zero opacity and undefined red, green and blue channels; this differs slightly from CSS which defines it as transparent black, but is useful for simplifying color interpolation logic where either the starting or ending color has undefined channels. The [*color*.toString](https://github.com/d3/d3-color/blob/master/README.md#color_toString) method now likewise returns an rgb(…) or rgba(…) string with integer channel values, not the hexadecimal RGB format, consistent with CSS computed values. This improves performance by short-circuiting transitions when the element’s starting style matches its ending style. - -The new [d3.color](https://github.com/d3/d3-color/blob/master/README.md#color) method is the primary method for parsing colors: it returns a d3.color instance in the appropriate color space, or null if the CSS color specifier is invalid. For example: - -```js -var red = d3.color("hsl(0, 80%, 50%)"); // {h: 0, l: 0.5, s: 0.8, opacity: 1} -``` - -The parsing implementation is now more robust. For example, you can no longer mix integers and percentages in rgb(…), and it correctly handles whitespace, decimal points, number signs, and other edge cases. The color space constructors d3.rgb, d3.hsl, d3.lab, d3.hcl and d3.cubehelix now always return a copy of the input color, converted to the corresponding color space. While [*color*.rgb](https://github.com/d3/d3-color/blob/master/README.md#color_rgb) remains, *rgb*.hsl has been removed; use d3.hsl to convert a color to the RGB color space. - -The RGB color space no longer greedily quantizes and clamps channel values when creating colors, improving accuracy in color space conversion. Quantization and clamping now occurs in *color*.toString when formatting a color for display. You can use the new [*color*.displayable](https://github.com/d3/d3-color/blob/master/README.md#color_displayable) to test whether a color is [out-of-gamut](https://en.wikipedia.org/wiki/Gamut). - -The [*rgb*.brighter](https://github.com/d3/d3-color/blob/master/README.md#rgb_brighter) method no longer special-cases black. This is a multiplicative operator, defining a new color *r*′, *g*′, *b*′ where *r*′ = *r* × *pow*(0.7, *k*), *g*′ = *g* × *pow*(0.7, *k*) and *b*′ = *b* × *pow*(0.7, *k*); a brighter black is still black. - -There’s a new [d3.cubehelix](https://github.com/d3/d3-color/blob/master/README.md#cubehelix) color space, generalizing Dave Green’s color scheme! (See also [d3.interpolateCubehelixDefault](https://github.com/d3/d3-scale/blob/master/README.md#interpolateCubehelixDefault) from [d3-scale](#scales-d3-scale).) You can continue to define your own custom color spaces, too; see [d3-hsv](https://github.com/d3/d3-hsv) for an example. - -## [Dispatches (d3-dispatch)](https://github.com/d3/d3-dispatch/blob/master/README.md) - -Rather than decorating the *dispatch* object with each event type, the dispatch object now exposes generic [*dispatch*.call](https://github.com/d3/d3-dispatch/blob/master/README.md#dispatch_call) and [*dispatch*.apply](https://github.com/d3/d3-dispatch/blob/master/README.md#dispatch_apply) methods which take the *type* string as the first argument. For example, in D3 3.x, you might say: - -```js -dispatcher.foo.call(that, "Hello, Foo!"); -``` - -To dispatch a *foo* event in D3 4.0, you’d say: - -```js -dispatcher.call("foo", that, "Hello, Foo!"); -``` - -The [*dispatch*.on](https://github.com/d3/d3-dispatch/blob/master/README.md#dispatch_on) method now accepts multiple typenames, allowing you to add or remove listeners for multiple events simultaneously. For example, to send both *foo* and *bar* events to the same listener: - -```js -dispatcher.on("foo bar", function(message) { - console.log(message); -}); -``` - -This matches the new behavior of [*selection*.on](https://github.com/d3/d3-selection/blob/master/README.md#selection_on) in [d3-selection](#selections-d3-selection). The *dispatch*.on method now validates that the specifier *listener* is a function, rather than throwing an error in the future. - -The new implementation d3.dispatch is faster, using fewer closures to improve performance. There’s also a new [*dispatch*.copy](https://github.com/d3/d3-dispatch/blob/master/README.md#dispatch_copy) method for making a copy of a dispatcher; this is used by [d3-transition](#transitions-d3-transition) to improve the performance of transitions in the common case where all elements in a transition have the same transition event listeners. - -## [Dragging (d3-drag)](https://github.com/d3/d3-drag/blob/master/README.md) - -The drag behavior d3.behavior.drag has been renamed to d3.drag. The *drag*.origin method has been replaced by [*drag*.subject](https://github.com/d3/d3-drag/blob/master/README.md#drag_subject), which allows you to define the thing being dragged at the start of a drag gesture. This is particularly useful with Canvas, where draggable objects typically share a Canvas element (as opposed to SVG, where draggable objects typically have distinct DOM elements); see the [circle dragging example](https://bl.ocks.org/mbostock/444757cc9f0fde320a5f469cd36860f4). - -A new [*drag*.container](https://github.com/d3/d3-drag/blob/master/README.md#drag_container) method lets you override the parent element that defines the drag gesture coordinate system. This defaults to the parent node of the element to which the drag behavior was applied. For dragging on Canvas elements, you probably want to use the Canvas element as the container. - -[Drag events](https://github.com/d3/d3-drag/blob/master/README.md#drag-events) now expose an [*event*.on](https://github.com/d3/d3-drag/blob/master/README.md#event_on) method for registering temporary listeners for duration of the current drag gesture; these listeners can capture state for the current gesture, such as the thing being dragged. A new *event*.active property lets you detect whether multiple (multitouch) drag gestures are active concurrently. The *dragstart* and *dragend* events have been renamed to *start* and *end*. By default, drag behaviors now ignore right-clicks intended for the context menu; use [*drag*.filter](https://github.com/d3/d3-drag/blob/master/README.md#drag_filter) to control which events are ignored. The drag behavior also ignores emulated mouse events on iOS. The drag behavior now consumes handled events, making it easier to combine with other interactive behaviors such as [zooming](#zooming-d3-zoom). - -The new [d3.dragEnable](https://github.com/d3/d3-drag/blob/master/README.md#dragEnable) and [d3.dragDisable](https://github.com/d3/d3-drag/blob/master/README.md#dragDisable) methods provide a low-level API for implementing drag gestures across browsers and devices. These methods are also used by other D3 components, such as the [brush](#brushes-d3-brush). - -## [Delimiter-Separated Values (d3-dsv)](https://github.com/d3/d3-dsv/blob/master/README.md) - -Pursuant to the great namespace flattening, various CSV and TSV methods have new names: - -* d3.csv.parse ↦ [d3.csvParse](https://github.com/d3/d3-dsv/blob/master/README.md#csvParse) -* d3.csv.parseRows ↦ [d3.csvParseRows](https://github.com/d3/d3-dsv/blob/master/README.md#csvParseRows) -* d3.csv.format ↦ [d3.csvFormat](https://github.com/d3/d3-dsv/blob/master/README.md#csvFormat) -* d3.csv.formatRows ↦ [d3.csvFormatRows](https://github.com/d3/d3-dsv/blob/master/README.md#csvFormatRows) -* d3.tsv.parse ↦ [d3.tsvParse](https://github.com/d3/d3-dsv/blob/master/README.md#tsvParse) -* d3.tsv.parseRows ↦ [d3.tsvParseRows](https://github.com/d3/d3-dsv/blob/master/README.md#tsvParseRows) -* d3.tsv.format ↦ [d3.tsvFormat](https://github.com/d3/d3-dsv/blob/master/README.md#tsvFormat) -* d3.tsv.formatRows ↦ [d3.tsvFormatRows](https://github.com/d3/d3-dsv/blob/master/README.md#tsvFormatRows) - -The [d3.csv](https://github.com/d3/d3-request/blob/master/README.md#csv) and [d3.tsv](https://github.com/d3/d3-request/blob/master/README.md#tsv) methods for loading files of the corresponding formats have not been renamed, however! Those are defined in [d3-request](#requests-d3-request).There’s no longer a d3.dsv method, which served the triple purpose of defining a DSV formatter, a DSV parser and a DSV requestor; instead, there’s just [d3.dsvFormat](https://github.com/d3/d3-dsv/blob/master/README.md#dsvFormat) which you can use to define a DSV formatter and parser. You can use [*request*.response](https://github.com/d3/d3-request/blob/master/README.md#request_response) to make a request and then parse the response body, or just use [d3.text](https://github.com/d3/d3-request/blob/master/README.md#text). - -The [*dsv*.parse](https://github.com/d3/d3-dsv/blob/master/README.md#dsv_parse) method now exposes the column names and their input order as *data*.columns. For example: - -```js -d3.csv("cars.csv", function(error, data) { - if (error) throw error; - console.log(data.columns); // ["Year", "Make", "Model", "Length"] -}); -``` - -You can likewise pass an optional array of column names to [*dsv*.format](https://github.com/d3/d3-dsv/blob/master/README.md#dsv_format) to format only a subset of columns, or to specify the column order explicitly: - -```js -var string = d3.csvFormat(data, ["Year", "Model", "Length"]); -``` - -The parser is a bit faster and the formatter is a bit more robust: inputs are coerced to strings before formatting, fixing an obscure crash, and deprecated support for falling back to [*dsv*.formatRows](https://github.com/d3/d3-dsv/blob/master/README.md#dsv_formatRows) when the input *data* is an array of arrays has been removed. - -## [Easings (d3-ease)](https://github.com/d3/d3-ease/blob/master/README.md) - -D3 3.x used strings, such as “cubic-in-out”, to identify easing methods; these strings could be passed to d3.ease or *transition*.ease. D3 4.0 uses symbols instead, such as [d3.easeCubicInOut](https://github.com/d3/d3-ease/blob/master/README.md#easeCubicInOut). Symbols are simpler and cleaner. They work well with Rollup to produce smaller custom bundles. You can still define your own custom easing function, too, if desired. Here’s the full list of equivalents: - -* linear ↦ [d3.easeLinear](https://github.com/d3/d3-ease/blob/master/README.md#easeLinear)¹ -* linear-in ↦ [d3.easeLinear](https://github.com/d3/d3-ease/blob/master/README.md#easeLinear)¹ -* linear-out ↦ [d3.easeLinear](https://github.com/d3/d3-ease/blob/master/README.md#easeLinear)¹ -* linear-in-out ↦ [d3.easeLinear](https://github.com/d3/d3-ease/blob/master/README.md#easeLinear)¹ -* linear-out-in ↦ [d3.easeLinear](https://github.com/d3/d3-ease/blob/master/README.md#easeLinear)¹ -* poly-in ↦ [d3.easePolyIn](https://github.com/d3/d3-ease/blob/master/README.md#easePolyIn) -* poly-out ↦ [d3.easePolyOut](https://github.com/d3/d3-ease/blob/master/README.md#easePolyOut) -* poly-in-out ↦ [d3.easePolyInOut](https://github.com/d3/d3-ease/blob/master/README.md#easePolyInOut) -* poly-out-in ↦ REMOVED² -* quad-in ↦ [d3.easeQuadIn](https://github.com/d3/d3-ease/blob/master/README.md#easeQuadIn) -* quad-out ↦ [d3.easeQuadOut](https://github.com/d3/d3-ease/blob/master/README.md#easeQuadOut) -* quad-in-out ↦ [d3.easeQuadInOut](https://github.com/d3/d3-ease/blob/master/README.md#easeQuadInOut) -* quad-out-in ↦ REMOVED² -* cubic-in ↦ [d3.easeCubicIn](https://github.com/d3/d3-ease/blob/master/README.md#easeCubicIn) -* cubic-out ↦ [d3.easeCubicOut](https://github.com/d3/d3-ease/blob/master/README.md#easeCubicOut) -* cubic-in-out ↦ [d3.easeCubicInOut](https://github.com/d3/d3-ease/blob/master/README.md#easeCubicInOut) -* cubic-out-in ↦ REMOVED² -* sin-in ↦ [d3.easeSinIn](https://github.com/d3/d3-ease/blob/master/README.md#easeSinIn) -* sin-out ↦ [d3.easeSinOut](https://github.com/d3/d3-ease/blob/master/README.md#easeSinOut) -* sin-in-out ↦ [d3.easeSinInOut](https://github.com/d3/d3-ease/blob/master/README.md#easeSinInOut) -* sin-out-in ↦ REMOVED² -* exp-in ↦ [d3.easeExpIn](https://github.com/d3/d3-ease/blob/master/README.md#easeExpIn) -* exp-out ↦ [d3.easeExpOut](https://github.com/d3/d3-ease/blob/master/README.md#easeExpOut) -* exp-in-out ↦ [d3.easeExpInOut](https://github.com/d3/d3-ease/blob/master/README.md#easeExpInOut) -* exp-out-in ↦ REMOVED² -* circle-in ↦ [d3.easeCircleIn](https://github.com/d3/d3-ease/blob/master/README.md#easeCircleIn) -* circle-out ↦ [d3.easeCircleOut](https://github.com/d3/d3-ease/blob/master/README.md#easeCircleOut) -* circle-in-out ↦ [d3.easeCircleInOut](https://github.com/d3/d3-ease/blob/master/README.md#easeCircleInOut) -* circle-out-in ↦ REMOVED² -* elastic-in ↦ [d3.easeElasticOut](https://github.com/d3/d3-ease/blob/master/README.md#easeElasticOut)² -* elastic-out ↦ [d3.easeElasticIn](https://github.com/d3/d3-ease/blob/master/README.md#easeElasticIn)² -* elastic-in-out ↦ REMOVED² -* elastic-out-in ↦ [d3.easeElasticInOut](https://github.com/d3/d3-ease/blob/master/README.md#easeElasticInOut)² -* back-in ↦ [d3.easeBackIn](https://github.com/d3/d3-ease/blob/master/README.md#easeBackIn) -* back-out ↦ [d3.easeBackOut](https://github.com/d3/d3-ease/blob/master/README.md#easeBackOut) -* back-in-out ↦ [d3.easeBackInOut](https://github.com/d3/d3-ease/blob/master/README.md#easeBackInOut) -* back-out-in ↦ REMOVED² -* bounce-in ↦ [d3.easeBounceOut](https://github.com/d3/d3-ease/blob/master/README.md#easeBounceOut)² -* bounce-out ↦ [d3.easeBounceIn](https://github.com/d3/d3-ease/blob/master/README.md#easeBounceIn)² -* bounce-in-out ↦ REMOVED² -* bounce-out-in ↦ [d3.easeBounceInOut](https://github.com/d3/d3-ease/blob/master/README.md#easeBounceInOut)² - -¹ The -in, -out and -in-out variants of linear easing are identical, so there’s just d3.easeLinear. -
² Elastic and bounce easing were inadvertently reversed in 3.x, so 4.0 eliminates -out-in easing! - -For convenience, there are also default aliases for each easing method. For example, [d3.easeCubic](https://github.com/d3/d3-ease/blob/master/README.md#easeCubic) is an alias for [d3.easeCubicInOut](https://github.com/d3/d3-ease/blob/master/README.md#easeCubicInOut). Most default to -in-out; the exceptions are [d3.easeBounce](https://github.com/d3/d3-ease/blob/master/README.md#easeBounce) and [d3.easeElastic](https://github.com/d3/d3-ease/blob/master/README.md#easeElastic), which default to -out. - -Rather than pass optional arguments to d3.ease or *transition*.ease, parameterizable easing functions now have named parameters: [*poly*.exponent](https://github.com/d3/d3-ease/blob/master/README.md#poly_exponent), [*elastic*.amplitude](https://github.com/d3/d3-ease/blob/master/README.md#elastic_amplitude), [*elastic*.period](https://github.com/d3/d3-ease/blob/master/README.md#elastic_period) and [*back*.overshoot](https://github.com/d3/d3-ease/blob/master/README.md#back_overshoot). For example, in D3 3.x you might say: - -```js -var e = d3.ease("elastic-out-in", 1.2); -``` - -The equivalent in D3 4.0 is: - -```js -var e = d3.easeElastic.amplitude(1.2); -``` - -Many of the easing functions have been optimized for performance and accuracy. Several bugs have been fixed, as well, such as the interpretation of the overshoot parameter for back easing, and the period parameter for elastic easing. Also, [d3-transition](#transitions-d3-transition) now explicitly guarantees that the last tick of the transition happens at exactly *t* = 1, avoiding floating point errors in some easing functions. - -There’s now a nice [visual reference](https://github.com/d3/d3-ease/blob/master/README.md) and an [animated reference](https://bl.ocks.org/mbostock/248bac3b8e354a9103c4) to the new easing functions, too! - -## [Forces (d3-force)](https://github.com/d3/d3-force/blob/master/README.md) - -The force layout d3.layout.force has been renamed to d3.forceSimulation. The force simulation now uses [velocity Verlet integration](https://en.wikipedia.org/wiki/Verlet_integration#Velocity_Verlet) rather than position Verlet, tracking the nodes’ positions (*node*.x, *node*.y) and velocities (*node*.vx, *node*.vy) rather than their previous positions (*node*.px, *node*.py). - -Rather than hard-coding a set of built-in forces, the force simulation is now extensible: you specify which forces you want! The approach affords greater flexibility through composition. The new forces are more flexible, too: force parameters can typically be configured per-node or per-link. There are separate positioning forces for [*x*](https://github.com/d3/d3-force/blob/master/README.md#forceX) and [*y*](https://github.com/d3/d3-force/blob/master/README.md#forceY) that replace *force*.gravity; [*x*.x](https://github.com/d3/d3-force/blob/master/README.md#x_x) and [*y*.y](https://github.com/d3/d3-force/blob/master/README.md#y_y) replace *force*.size. The new [link force](https://github.com/d3/d3-force/blob/master/README.md#forceLink) replaces *force*.linkStrength and employs better default heuristics to improve stability. The new [many-body force](https://github.com/d3/d3-force/blob/master/README.md#forceManyBody) replaces *force*.charge and supports a new [minimum-distance parameter](https://github.com/d3/d3-force/blob/master/README.md#manyBody_distanceMin) and performance improvements thanks to 4.0’s [new quadtrees](#quadtrees-d3-quadtree). There are also brand-new forces for [centering nodes](https://github.com/d3/d3-force/blob/master/README.md#forceCenter) and [collision resolution](https://github.com/d3/d3-force/blob/master/README.md#forceCollision). - -The new forces and simulation have been carefully crafted to avoid nondeterminism. Rather than initializing nodes randomly, if the nodes do not have preset positions, they are placed in a phyllotaxis pattern: - -Phyllotaxis - -Random jitter is still needed to resolve link, collision and many-body forces if there are coincident nodes, but at least in the common case, the force simulation (and the resulting force-directed graph layout) is now consistent across browsers and reloads. D3 no longer plays dice! - -The force simulation has several new methods for greater control over heating, such as [*simulation*.alphaMin](https://github.com/d3/d3-force/blob/master/README.md#simulation_alphaMin) and [*simulation*.alphaDecay](https://github.com/d3/d3-force/blob/master/README.md#simulation_alphaDecay), and the internal timer. Calling [*simulation*.alpha](https://github.com/d3/d3-force/blob/master/README.md#simulation_alpha) now has no effect on the internal timer, which is controlled independently via [*simulation*.stop](https://github.com/d3/d3-force/blob/master/README.md#simulation_stop) and [*simulation*.restart](https://github.com/d3/d3-force/blob/master/README.md#simulation_restart). The force layout’s internal timer now starts automatically on creation, removing *force*.start. As in 3.x, you can advance the simulation manually using [*simulation*.tick](https://github.com/d3/d3-force/blob/master/README.md#simulation_tick). The *force*.friction parameter is replaced by *simulation*.velocityDecay. A new [*simulation*.alphaTarget](https://github.com/d3/d3-force/blob/master/README.md#simulation_alphaTarget) method allows you to set the desired alpha (temperature) of the simulation, such that the simulation can be smoothly reheated during interaction, and then smoothly cooled again. This improves the stability of the graph during interaction. - -The force layout no longer depends on the [drag behavior](#dragging-d3-drag), though you can certainly create [draggable force-directed graphs](https://bl.ocks.org/mbostock/ad70335eeef6d167bc36fd3c04378048)! Set *node*.fx and *node*.fy to fix a node’s position. As an alternative to a [Voronoi](#voronoi-d3-voronoi) SVG overlay, you can now use [*simulation*.find](https://github.com/d3/d3-force/blob/master/README.md#simulation_find) to find the closest node to a pointer. - -## [Number Formats (d3-format)](https://github.com/d3/d3-format/blob/master/README.md) - -If a precision is not specified, the formatting behavior has changed: there is now a default precision of 6 for all directives except *none*, which defaults to 12. In 3.x, if you did not specify a precision, the number was formatted using its shortest unique representation (per [*number*.toString](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toString)); this could lead to unexpected digits due to [floating point math](http://0.30000000000000004.com/). The new default precision in 4.0 produces more consistent results: - -```js -var f = d3.format("e"); -f(42); // "4.200000e+1" -f(0.1 + 0.2); // "3.000000e-1" -``` - -To trim insignificant trailing zeroes, use the *none* directive, which is similar `g`. For example: - -```js -var f = d3.format(".3"); -f(0.12345); // "0.123" -f(0.10000); // "0.1" -f(0.1 + 0.2); // "0.3" -``` - -Under the hood, number formatting has improved accuracy with very large and very small numbers by using [*number*.toExponential](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toExponential) rather than [Math.log](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/log) to extract the mantissa and exponent. Negative zero (-0, an IEEE 754 construct) and very small numbers that round to zero are now formatted as unsigned zero. The inherently unsafe d3.round method has been removed, along with d3.requote. - -The [d3.formatPrefix](https://github.com/d3/d3-format/blob/master/README.md#formatPrefix) method has been changed. Rather than returning an SI-prefix string, it returns an SI-prefix format function for a given *specifier* and reference *value*. For example, to format thousands: - -```js -var f = d3.formatPrefix(",.0", 1e3); -f(1e3); // "1k" -f(1e4); // "10k" -f(1e5); // "100k" -f(1e6); // "1,000k" -``` - -Unlike the `s` format directive, d3.formatPrefix always employs the same SI-prefix, producing consistent results: - -```js -var f = d3.format(".0s"); -f(1e3); // "1k" -f(1e4); // "10k" -f(1e5); // "100k" -f(1e6); // "1M" -``` - -The new `(` sign option uses parentheses for negative values. This is particularly useful in conjunction with `$`. For example: - -```js -d3.format("+.0f")(-42); // "-42" -d3.format("(.0f")(-42); // "(42)" -d3.format("+$.0f")(-42); // "-$42" -d3.format("($.0f")(-42); // "($42)" -``` - -The new `=` align option places any sign and symbol to the left of any padding: - -```js -d3.format(">6d")(-42); // " -42" -d3.format("=6d")(-42); // "- 42" -d3.format(">(6d")(-42); // " (42)" -d3.format("=(6d")(-42); // "( 42)" -``` - -The `b`, `o`, `d` and `x` directives now round to the nearest integer, rather than returning the empty string for non-integers: - -```js -d3.format("b")(41.9); // "101010" -d3.format("o")(41.9); // "52" -d3.format("d")(41.9); // "42" -d3.format("x")(41.9); // "2a" -``` - -The `c` directive is now for character data (*i.e.*, literal strings), not for character codes. The is useful if you just want to apply padding and alignment and don’t care about formatting numbers. For example, the infamous [left-pad](http://blog.npmjs.org/post/141577284765/kik-left-pad-and-npm) (as well as center- and right-pad!) can be conveniently implemented as: - -```js -d3.format(">10c")("foo"); // " foo" -d3.format("^10c")("foo"); // " foo " -d3.format("<10c")("foo"); // "foo " -``` - -There are several new methods for computing suggested decimal precisions; these are used by [d3-scale](#scales-d3-scale) for tick formatting, and are helpful for implementing custom number formats: [d3.precisionFixed](https://github.com/d3/d3-format/blob/master/README.md#precisionFixed), [d3.precisionPrefix](https://github.com/d3/d3-format/blob/master/README.md#precisionPrefix) and [d3.precisionRound](https://github.com/d3/d3-format/blob/master/README.md#precisionRound). There’s also a new [d3.formatSpecifier](https://github.com/d3/d3-format/blob/master/README.md#formatSpecifier) method for parsing, validating and debugging format specifiers; it’s also good for deriving related format specifiers, such as when you want to substitute the precision automatically. - -You can now set the default locale using [d3.formatDefaultLocale](https://github.com/d3/d3-format/blob/master/README.md#formatDefaultLocale)! The locales are published as [JSON](https://github.com/d3/d3-request/blob/master/README.md#json) to [npm](https://unpkg.com/d3-format/locale/). - -## [Geographies (d3-geo)](https://github.com/d3/d3-geo/blob/master/README.md) - -Pursuant to the great namespace flattening, various methods have new names: - -* d3.geo.graticule ↦ [d3.geoGraticule](https://github.com/d3/d3-geo/blob/master/README.md#geoGraticule) -* d3.geo.circle ↦ [d3.geoCircle](https://github.com/d3/d3-geo/blob/master/README.md#geoCircle) -* d3.geo.area ↦ [d3.geoArea](https://github.com/d3/d3-geo/blob/master/README.md#geoArea) -* d3.geo.bounds ↦ [d3.geoBounds](https://github.com/d3/d3-geo/blob/master/README.md#geoBounds) -* d3.geo.centroid ↦ [d3.geoCentroid](https://github.com/d3/d3-geo/blob/master/README.md#geoCentroid) -* d3.geo.distance ↦ [d3.geoDistance](https://github.com/d3/d3-geo/blob/master/README.md#geoDistance) -* d3.geo.interpolate ↦ [d3.geoInterpolate](https://github.com/d3/d3-geo/blob/master/README.md#geoInterpolate) -* d3.geo.length ↦ [d3.geoLength](https://github.com/d3/d3-geo/blob/master/README.md#geoLength) -* d3.geo.rotation ↦ [d3.geoRotation](https://github.com/d3/d3-geo/blob/master/README.md#geoRotation) -* d3.geo.stream ↦ [d3.geoStream](https://github.com/d3/d3-geo/blob/master/README.md#geoStream) -* d3.geo.path ↦ [d3.geoPath](https://github.com/d3/d3-geo/blob/master/README.md#geoPath) -* d3.geo.projection ↦ [d3.geoProjection](https://github.com/d3/d3-geo/blob/master/README.md#geoProjection) -* d3.geo.projectionMutator ↦ [d3.geoProjectionMutator](https://github.com/d3/d3-geo/blob/master/README.md#geoProjectionMutator) -* d3.geo.albers ↦ [d3.geoAlbers](https://github.com/d3/d3-geo/blob/master/README.md#geoAlbers) -* d3.geo.albersUsa ↦ [d3.geoAlbersUsa](https://github.com/d3/d3-geo/blob/master/README.md#geoAlbersUsa) -* d3.geo.azimuthalEqualArea ↦ [d3.geoAzimuthalEqualArea](https://github.com/d3/d3-geo/blob/master/README.md#geoAzimuthalEqualArea) -* d3.geo.azimuthalEquidistant ↦ [d3.geoAzimuthalEquidistant](https://github.com/d3/d3-geo/blob/master/README.md#geoAzimuthalEquidistant) -* d3.geo.conicConformal ↦ [d3.geoConicConformal](https://github.com/d3/d3-geo/blob/master/README.md#geoConicConformal) -* d3.geo.conicEqualArea ↦ [d3.geoConicEqualArea](https://github.com/d3/d3-geo/blob/master/README.md#geoConicEqualArea) -* d3.geo.conicEquidistant ↦ [d3.geoConicEquidistant](https://github.com/d3/d3-geo/blob/master/README.md#geoConicEquidistant) -* d3.geo.equirectangular ↦ [d3.geoEquirectangular](https://github.com/d3/d3-geo/blob/master/README.md#geoEquirectangular) -* d3.geo.gnomonic ↦ [d3.geoGnomonic](https://github.com/d3/d3-geo/blob/master/README.md#geoGnomonic) -* d3.geo.mercator ↦ [d3.geoMercator](https://github.com/d3/d3-geo/blob/master/README.md#geoMercator) -* d3.geo.orthographic ↦ [d3.geoOrthographic](https://github.com/d3/d3-geo/blob/master/README.md#geoOrthographic) -* d3.geo.stereographic ↦ [d3.geoStereographic](https://github.com/d3/d3-geo/blob/master/README.md#geoStereographic) -* d3.geo.transverseMercator ↦ [d3.geoTransverseMercator](https://github.com/d3/d3-geo/blob/master/README.md#geoTransverseMercator) - -Also renamed for consistency: - -* *circle*.origin ↦ [*circle*.center](https://github.com/d3/d3-geo/blob/master/README.md#circle_center) -* *circle*.angle ↦ [*circle*.radius](https://github.com/d3/d3-geo/blob/master/README.md#circle_radius) -* *graticule*.majorExtent ↦ [*graticule*.extentMajor](https://github.com/d3/d3-geo/blob/master/README.md#graticule_extentMajor) -* *graticule*.minorExtent ↦ [*graticule*.extentMinor](https://github.com/d3/d3-geo/blob/master/README.md#graticule_extentMinor) -* *graticule*.majorStep ↦ [*graticule*.stepMajor](https://github.com/d3/d3-geo/blob/master/README.md#graticule_stepMajor) -* *graticule*.minorStep ↦ [*graticule*.stepMinor](https://github.com/d3/d3-geo/blob/master/README.md#graticule_stepMinor) - -Projections now have more appropriate defaults. For example, [d3.geoOrthographic](https://github.com/d3/d3-geo/blob/master/README.md#geoOrthographic) has a 90° clip angle by default, showing only the front hemisphere, and [d3.geoGnomonic](https://github.com/d3/d3-geo/blob/master/README.md#geoGnomonic) has a default 60° clip angle. The default [projection](https://github.com/d3/d3-geo/blob/master/README.md#path_projection) for [d3.geoPath](https://github.com/d3/d3-geo/blob/master/README.md#geoPath) is now null rather than [d3.geoAlbersUsa](https://github.com/d3/d3-geo/blob/master/README.md#geoAlbersUsa); a null projection is used with [pre-projected geometry](https://bl.ocks.org/mbostock/5557726) and is typically faster to render. - -“Fallback projections”—when you pass a function rather than a projection to [*path*.projection](https://github.com/d3/d3-geo/blob/master/README.md#path_projection)—are no longer supported. For geographic projections, use [d3.geoProjection](https://github.com/d3/d3-geo/blob/master/README.md#geoProjection) or [d3.geoProjectionMutator](https://github.com/d3/d3-geo/blob/master/README.md#geoProjectionMutator) to define a custom projection. For arbitrary geometry transformations, implement the [stream interface](https://github.com/d3/d3-geo/blob/master/README.md#streams); see also [d3.geoTransform](https://github.com/d3/d3-geo/blob/master/README.md#geoTransform). The “raw” projections (e.g., d3.geo.equirectangular.raw) are no longer exported. - -## [Hierarchies (d3-hierarchy)](https://github.com/d3/d3-hierarchy/blob/master/README.md) - -Pursuant to the great namespace flattening: - -* d3.layout.cluster ↦ [d3.cluster](https://github.com/d3/d3-hierarchy/blob/master/README.md#cluster) -* d3.layout.hierarchy ↦ [d3.hierarchy](https://github.com/d3/d3-hierarchy/blob/master/README.md#hierarchy) -* d3.layout.pack ↦ [d3.pack](https://github.com/d3/d3-hierarchy/blob/master/README.md#pack) -* d3.layout.partition ↦ [d3.partition](https://github.com/d3/d3-hierarchy/blob/master/README.md#partition) -* d3.layout.tree ↦ [d3.tree](https://github.com/d3/d3-hierarchy/blob/master/README.md#tree) -* d3.layout.treemap ↦ [d3.treemap](https://github.com/d3/d3-hierarchy/blob/master/README.md#treemap) - -As an alternative to using JSON to represent hierarchical data (such as the “flare.json format” used by many D3 examples), the new [d3.stratify](https://github.com/d3/d3-hierarchy/blob/master/README.md#stratify) operator simplifies the conversion of tabular data to hierarchical data! This is convenient if you already have data in a tabular format, such as the result of a SQL query or a CSV file: - -``` -name,parent -Eve, -Cain,Eve -Seth,Eve -Enos,Seth -Noam,Seth -Abel,Eve -Awan,Eve -Enoch,Awan -Azura,Eve -``` - -To convert this to a root [*node*](https://github.com/d3/d3-hierarchy/blob/master/README.md#hierarchy): - -```js -var root = d3.stratify() - .id(function(d) { return d.name; }) - .parentId(function(d) { return d.parent; }) - (nodes); -``` - -The resulting *root* can be passed to [d3.tree](https://github.com/d3/d3-hierarchy/blob/master/README.md#tree) to produce a tree diagram like this: - - - -Root nodes can also be created from JSON data using [d3.hierarchy](https://github.com/d3/d3-hierarchy/blob/master/README.md#hierarchy). The hierarchy layouts now take these root nodes as input rather than operating directly on JSON data, which helps to provide a cleaner separation between the input data and the computed layout. (For example, use [*node*.copy](https://github.com/d3/d3-hierarchy/blob/master/README.md#node_copy) to isolate layout changes.) It also simplifies the API: rather than each hierarchy layout needing to implement value and sorting accessors, there are now generic [*node*.sum](https://github.com/d3/d3-hierarchy/blob/master/README.md#node_sum) and [*node*.sort](https://github.com/d3/d3-hierarchy/blob/master/README.md#node_sort) methods that work with any hierarchy layout. - -The new d3.hierarchy API also provides a richer set of methods for manipulating hierarchical data. For example, to generate an array of all nodes in topological order, use [*node*.descendants](https://github.com/d3/d3-hierarchy/blob/master/README.md#node_descendants); for just leaf nodes, use [*node*.leaves](https://github.com/d3/d3-hierarchy/blob/master/README.md#node_leaves). To highlight the ancestors of a given *node* on mouseover, use [*node*.ancestors](https://github.com/d3/d3-hierarchy/blob/master/README.md#node_ancestors). To generate an array of {source, target} links for a given hierarchy, use [*node*.links](https://github.com/d3/d3-hierarchy/blob/master/README.md#node_links); this replaces *treemap*.links and similar methods on the other layouts. The new [*node*.path](https://github.com/d3/d3-hierarchy/blob/master/README.md#node_path) method replaces d3.layout.bundle; see also [d3.curveBundle](https://github.com/d3/d3-shape/blob/master/README.md#curveBundle) for hierarchical edge bundling. - -The hierarchy layouts have been rewritten using new, non-recursive traversal methods ([*node*.each](https://github.com/d3/d3-hierarchy/blob/master/README.md#node_each), [*node*.eachAfter](https://github.com/d3/d3-hierarchy/blob/master/README.md#node_eachAfter) and [*node*.eachBefore](https://github.com/d3/d3-hierarchy/blob/master/README.md#node_eachBefore)), improving performance on large datasets. The d3.tree layout no longer uses a *node*.\_ field to store temporary state during layout. - -Treemap tiling is now [extensible](https://github.com/d3/d3-hierarchy/blob/master/README.md#treemap-tiling) via [*treemap*.tile](https://github.com/d3/d3-hierarchy/blob/master/README.md#treemap_tile)! The default squarified tiling algorithm, [d3.treemapSquarify](https://github.com/d3/d3-hierarchy/blob/master/README.md#treemapSquarify), has been completely rewritten, improving performance and fixing bugs in padding and rounding. The *treemap*.sticky method has been replaced with the [d3.treemapResquarify](https://github.com/d3/d3-hierarchy/blob/master/README.md#treemapResquarify), which is identical to d3.treemapSquarify except it performs stable neighbor-preserving updates. The *treemap*.ratio method has been replaced with [*squarify*.ratio](https://github.com/d3/d3-hierarchy/blob/master/README.md#squarify_ratio). And there’s a new [d3.treemapBinary](https://github.com/d3/d3-hierarchy/blob/master/README.md#treemapBinary) for binary treemaps! - -Treemap padding has also been improved. The treemap now distinguishes between [outer padding](https://github.com/d3/d3-hierarchy/blob/master/README.md#treemap_paddingOuter) that separates a parent from its children, and [inner padding](https://github.com/d3/d3-hierarchy/blob/master/README.md#treemap_paddingInner) that separates adjacent siblings. You can set the [top-](https://github.com/d3/d3-hierarchy/blob/master/README.md#treemap_paddingTop), [right-](https://github.com/d3/d3-hierarchy/blob/master/README.md#treemap_paddingRight), [bottom-](https://github.com/d3/d3-hierarchy/blob/master/README.md#treemap_paddingBottom) and [left-](https://github.com/d3/d3-hierarchy/blob/master/README.md#treemap_paddingLeft)outer padding separately. There are new examples for the traditional [nested treemap](https://bl.ocks.org/mbostock/911ad09bdead40ec0061) and for Lü and Fogarty’s [cascaded treemap](https://bl.ocks.org/mbostock/f85ffb3a5ac518598043). And there’s a new example demonstrating [d3.nest with d3.treemap](https://bl.ocks.org/mbostock/2838bf53e0e65f369f476afd653663a2). - -The space-filling layouts [d3.treemap](https://github.com/d3/d3-hierarchy/blob/master/README.md#treemap) and [d3.partition](https://github.com/d3/d3-hierarchy/blob/master/README.md#partition) now output *x0*, *x1*, *y0*, *y1* on each node instead of *x0*, *dx*, *y0*, *dy*. This improves accuracy by ensuring that the edges of adjacent cells are exactly equal, rather than sometimes being slightly off due to floating point math. The partition layout now supports [rounding](https://github.com/d3/d3-hierarchy/blob/master/README.md#partition_round) and [padding](https://github.com/d3/d3-hierarchy/blob/master/README.md#partition_padding). - -The circle-packing layout, [d3.pack](https://github.com/d3/d3-hierarchy/blob/master/README.md#pack), has been completely rewritten to better implement Wang et al.’s algorithm, fixing major bugs and improving results! Welzl’s algorithm is now used to compute the exact [smallest enclosing circle](https://bl.ocks.org/mbostock/29c534ff0b270054a01c) for each parent, rather than the approximate answer used by Wang et al. The 3.x output is shown on the left; 4.0 is shown on the right: - -Circle Packing in 3.x Circle Packing in 4.0 - -A non-hierarchical implementation is also available as [d3.packSiblings](https://github.com/d3/d3-hierarchy/blob/master/README.md#packSiblings), and the smallest enclosing circle implementation is available as [d3.packEnclose](https://github.com/d3/d3-hierarchy/blob/master/README.md#packEnclose). [Pack padding](https://github.com/d3/d3-hierarchy/blob/master/README.md#pack_padding) now applies between a parent and its children, as well as between adjacent siblings. In addition, you can now specify padding as a function that is computed dynamically for each parent. - -## Internals - -The d3.rebind method has been removed. (See the [3.x source](https://github.com/d3/d3/blob/v3.5.17/src/core/rebind.js).) If you want to wrap a getter-setter method, the recommend pattern is to implement a wrapper method and check the return value. For example, given a *component* that uses an internal [*dispatch*](#dispatches-d3-dispatch), *component*.on can rebind *dispatch*.on as follows: - -```js -component.on = function() { - var value = dispatch.on.apply(dispatch, arguments); - return value === dispatch ? component : value; -}; -``` - -The d3.functor method has been removed. (See the [3.x source](https://github.com/d3/d3/blob/v3.5.17/src/core/functor.js).) If you want to promote a constant value to a function, the recommended pattern is to implement a closure that returns the constant value. If desired, you can use a helper method as follows: - -```js -function constant(x) { - return function() { - return x; - }; -} -``` - -Given a value *x*, to promote *x* to a function if it is not already: - -```js -var fx = typeof x === "function" ? x : constant(x); -``` - -## [Interpolators (d3-interpolate)](https://github.com/d3/d3-interpolate/blob/master/README.md) - -The [d3.interpolate](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolate) method no longer delegates to d3.interpolators, which has been removed; its behavior is now defined by the library. It is now slightly faster in the common case that *b* is a number. It only uses [d3.interpolateRgb](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateRgb) if *b* is a valid CSS color specifier (and not approximately one). And if the end value *b* is null, undefined, true or false, d3.interpolate now returns a constant function which always returns *b*. - -The behavior of [d3.interpolateObject](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateObject) and [d3.interpolateArray](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateArray) has changed slightly with respect to properties or elements in the start value *a* that do not exist in the end value *b*: these properties and elements are now ignored, such that the ending value of the interpolator at *t* = 1 is now precisely equal to *b*. So, in 3.x: - -```js -d3.interpolateObject({foo: 2, bar: 1}, {foo: 3})(0.5); // {bar: 1, foo: 2.5} in 3.x -``` - -Whereas in 4.0, *a*.bar is ignored: - -```js -d3.interpolateObject({foo: 2, bar: 1}, {foo: 3})(0.5); // {foo: 2.5} in 4.0 -``` - -If *a* or *b* are undefined or not an object, they are now implicitly converted to the empty object or empty array as appropriate, rather than throwing a TypeError. - -The d3.interpolateTransform interpolator has been renamed to [d3.interpolateTransformSvg](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateTransformSvg), and there is a new [d3.interpolateTransformCss](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateTransformCss) to interpolate CSS transforms! This allows [d3-transition](#transitions-d3-transition) to automatically interpolate both the SVG [transform attribute](https://www.w3.org/TR/SVG/coords.html#TransformAttribute) and the CSS [transform style property](https://www.w3.org/TR/css-transforms-1/#transform-property). (Note, however, that only 2D CSS transforms are supported.) The d3.transform method has been removed. - -Color space interpolators now interpolate opacity (see [d3-color](#colors-d3-color)) and return rgb(…) or rgba(…) CSS color specifier strings rather than using the RGB hexadecimal format. This is necessary to support opacity interpolation, but is also beneficial because it matches CSS computed values. When a channel in the start color *a* is undefined, color interpolators now use the corresponding channel value from the end color *b*, or *vice versa*. This logic previously applied to some channels (such as saturation in HSL), but now applies to all channels in all color spaces, and is especially useful when interpolating to or from transparent. - -There are now “long” versions of cylindrical color space interpolators: [d3.interpolateHslLong](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateHslLong), [d3.interpolateHclLong](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateHclLong) and [d3.interpolateCubehelixLong](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateCubehelixLong). These interpolators use linear interpolation of hue, rather than using the shortest path around the 360° hue circle. See [d3.interpolateRainbow](https://github.com/d3/d3-scale/blob/master/README.md#interpolateRainbow) for an example. The Cubehelix color space is now supported by [d3-color](#colors-d3-color), and so there are now [d3.interpolateCubehelix](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateCubehelix) and [d3.interpolateCubehelixLong](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateCubehelixLong) interpolators. - -[Gamma-corrected color interpolation](https://web.archive.org/web/20160112115812/http://www.4p8.com/eric.brasseur/gamma.html) is now supported for both RGB and Cubehelix color spaces as [*interpolate*.gamma](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolate_gamma). For example, to interpolate from purple to orange with a gamma of 2.2 in RGB space: - -```js -var interpolate = d3.interpolateRgb.gamma(2.2)("purple", "orange"); -``` - -There are new interpolators for uniform non-rational [B-splines](https://en.wikipedia.org/wiki/B-spline)! These are useful for smoothly interpolating between an arbitrary sequence of values from *t* = 0 to *t* = 1, such as to generate a smooth color gradient from a discrete set of colors. The [d3.interpolateBasis](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateBasis) and [d3.interpolateBasisClosed](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateBasisClosed) interpolators generate one-dimensional B-splines, while [d3.interpolateRgbBasis](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateRgbBasis) and [d3.interpolateRgbBasisClosed](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateRgbBasisClosed) generate three-dimensional B-splines through RGB color space. These are used by [d3-scale-chromatic](https://github.com/d3/d3-scale-chromatic) to generate continuous color scales from ColorBrewer’s discrete color schemes, such as [PiYG](https://bl.ocks.org/mbostock/048d21cf747371b11884f75ad896e5a5). - -There’s also now a [d3.quantize](https://github.com/d3/d3-interpolate/blob/master/README.md#quantize) method for generating uniformly-spaced discrete samples from a continuous interpolator. This is useful for taking one of the built-in color scales (such as [d3.interpolateViridis](https://github.com/d3/d3-scale/blob/master/README.md#interpolateViridis)) and quantizing it for use with [d3.scaleQuantize](https://github.com/d3/d3-scale/blob/master/README.md#scaleQuantize), [d3.scaleQuantile](https://github.com/d3/d3-scale/blob/master/README.md#scaleQuantile) or [d3.scaleThreshold](https://github.com/d3/d3-scale/blob/master/README.md#scaleThreshold). - -## [Paths (d3-path)](https://github.com/d3/d3-path/blob/master/README.md) - -The [d3.path](https://github.com/d3/d3-path/blob/master/README.md#path) serializer implements the [CanvasPathMethods API](https://www.w3.org/TR/2dcontext/#canvaspathmethods), allowing you to write code that can render to either Canvas or SVG. For example, given some code that draws to a canvas: - -```js -function drawCircle(context, radius) { - context.moveTo(radius, 0); - context.arc(0, 0, radius, 0, 2 * Math.PI); -} -``` - -You can render to SVG as follows: - -```js -var context = d3.path(); -drawCircle(context, 40); -pathElement.setAttribute("d", context.toString()); -``` - -The path serializer enables [d3-shape](#shapes-d3-shape) to support both Canvas and SVG; see [*line*.context](https://github.com/d3/d3-shape/blob/master/README.md#line_context) and [*area*.context](https://github.com/d3/d3-shape/blob/master/README.md#area_context), for example. - -## [Polygons (d3-polygon)](https://github.com/d3/d3-polygon/blob/master/README.md) - -There’s no longer a d3.geom.polygon constructor; instead you just pass an array of vertices to the polygon methods. So instead of *polygon*.area and *polygon*.centroid, there’s [d3.polygonArea](https://github.com/d3/d3-polygon/blob/master/README.md#polygonArea) and [d3.polygonCentroid](https://github.com/d3/d3-polygon/blob/master/README.md#polygonCentroid). There are also new [d3.polygonContains](https://github.com/d3/d3-polygon/blob/master/README.md#polygonContains) and [d3.polygonLength](https://github.com/d3/d3-polygon/blob/master/README.md#polygonLength) methods. There’s no longer an equivalent to *polygon*.clip, but if [Sutherland–Hodgman clipping](https://en.wikipedia.org/wiki/Sutherland–Hodgman_algorithm) is needed, please [file a feature request](https://github.com/d3/d3-polygon/issues). - -The d3.geom.hull operator has been simplified: instead of an operator with *hull*.x and *hull*.y accessors, there’s just the [d3.polygonHull](https://github.com/d3/d3-polygon/blob/master/README.md#polygonHull) method which takes an array of points and returns the convex hull. - -## [Quadtrees (d3-quadtree)](https://github.com/d3/d3-quadtree/blob/master/README.md) - -The d3.geom.quadtree method has been replaced by [d3.quadtree](https://github.com/d3/d3-quadtree/blob/master/README.md#quadtree). 4.0 removes the concept of quadtree “generators” (configurable functions that build a quadtree from an array of data); there are now just quadtrees, which you can create via d3.quadtree and add data to via [*quadtree*.add](https://github.com/d3/d3-quadtree/blob/master/README.md#quadtree_add) and [*quadtree*.addAll](https://github.com/d3/d3-quadtree/blob/master/README.md#quadtree_addAll). This code in 3.x: - -```js -var quadtree = d3.geom.quadtree() - .extent([[0, 0], [width, height]]) - (data); -``` - -Can be rewritten in 4.0 as: - -```js -var quadtree = d3.quadtree() - .extent([[0, 0], [width, height]]) - .addAll(data); -``` - -The new quadtree implementation is vastly improved! It is no longer recursive, avoiding stack overflows when there are large numbers of coincident points. The internal storage is now more efficient, and the implementation is also faster; constructing a quadtree of 1M normally-distributed points takes about one second in 4.0, as compared to three seconds in 3.x. - -The change in [internal *node* structure](https://github.com/d3/d3-quadtree/blob/master/README.md#nodes) affects [*quadtree*.visit](https://github.com/d3/d3-quadtree/blob/master/README.md#quadtree_visit): use *node*.length to distinguish leaf nodes from internal nodes. For example, to iterate over all data in a quadtree: - -```js -quadtree.visit(function(node) { - if (!node.length) { - do { - console.log(node.data); - } while (node = node.next) - } -}); -``` - -There’s a new [*quadtree*.visitAfter](https://github.com/d3/d3-quadtree/blob/master/README.md#quadtree_visitAfter) method for visiting nodes in post-order traversal. This feature is used in [d3-force](#forces-d3-force) to implement the [Barnes–Hut approximation](https://en.wikipedia.org/wiki/Barnes–Hut_simulation). - -You can now remove data from a quadtree using [*quadtree*.remove](https://github.com/d3/d3-quadtree/blob/master/README.md#quadtree_remove) and [*quadtree*.removeAll](https://github.com/d3/d3-quadtree/blob/master/README.md#quadtree_removeAll). When adding data to a quadtree, the quadtree will now expand its extent by repeated doubling if the new point is outside the existing extent of the quadtree. There are also [*quadtree*.extent](https://github.com/d3/d3-quadtree/blob/master/README.md#quadtree_extent) and [*quadtree*.cover](https://github.com/d3/d3-quadtree/blob/master/README.md#quadtree_cover) methods for explicitly expanding the extent of the quadtree after creation. - -Quadtrees support several new utility methods: [*quadtree*.copy](https://github.com/d3/d3-quadtree/blob/master/README.md#quadtree_copy) returns a copy of the quadtree sharing the same data; [*quadtree*.data](https://github.com/d3/d3-quadtree/blob/master/README.md#quadtree_data) generates an array of all data in the quadtree; [*quadtree*.size](https://github.com/d3/d3-quadtree/blob/master/README.md#quadtree_size) returns the number of data points in the quadtree; and [*quadtree*.root](https://github.com/d3/d3-quadtree/blob/master/README.md#quadtree_root) returns the root node, which is useful for manual traversal of the quadtree. The [*quadtree*.find](https://github.com/d3/d3-quadtree/blob/master/README.md#quadtree_find) method now takes an optional search radius, which is useful for pointer-based selection in [force-directed graphs](https://bl.ocks.org/mbostock/ad70335eeef6d167bc36fd3c04378048). - -## [Queues (d3-queue)](https://github.com/d3/d3-queue/blob/master/README.md) - -Formerly known as Queue.js and queue-async, [d3.queue](https://github.com/d3/d3-queue) is now included in the default bundle, making it easy to load data files in parallel. It has been rewritten with fewer closures to improve performance, and there are now stricter checks in place to guarantee well-defined behavior. You can now use instanceof d3.queue and inspect the queue’s internal private state. - -## [Random Numbers (d3-random)](https://github.com/d3/d3-random/blob/master/README.md) - -Pursuant to the great namespace flattening, the random number generators have new names: - -* d3.random.normal ↦ [d3.randomNormal](https://github.com/d3/d3-random/blob/master/README.md#randomNormal) -* d3.random.logNormal ↦ [d3.randomLogNormal](https://github.com/d3/d3-random/blob/master/README.md#randomLogNormal) -* d3.random.bates ↦ [d3.randomBates](https://github.com/d3/d3-random/blob/master/README.md#randomBates) -* d3.random.irwinHall ↦ [d3.randomIrwinHall](https://github.com/d3/d3-random/blob/master/README.md#randomIrwinHall) - -There are also new random number generators for [exponential](https://github.com/d3/d3-random/blob/master/README.md#randomExponential) and [uniform](https://github.com/d3/d3-random/blob/master/README.md#randomUniform) distributions. The [normal](https://github.com/d3/d3-random/blob/master/README.md#randomNormal) and [log-normal](https://github.com/d3/d3-random/blob/master/README.md#randomLogNormal) random generators have been optimized. - -## [Requests (d3-request)](https://github.com/d3/d3-request/blob/master/README.md) - -The d3.xhr method has been renamed to [d3.request](https://github.com/d3/d3-request/blob/master/README.md#request). Basic authentication is now supported using [*request*.user](https://github.com/d3/d3-request/blob/master/README.md#request_user) and [*request*.password](https://github.com/d3/d3-request/blob/master/README.md#request_password). You can now configure a timeout using [*request*.timeout](https://github.com/d3/d3-request/blob/master/README.md#request_timeout). - -If an error occurs, the corresponding [ProgressEvent](https://xhr.spec.whatwg.org/#interface-progressevent) of type “error” is now passed to the error listener, rather than the [XMLHttpRequest](https://xhr.spec.whatwg.org/#interface-xmlhttprequest). Likewise, the ProgressEvent is passed to progress event listeners, rather than using [d3.event](https://github.com/d3/d3-selection/blob/master/README.md#event). If [d3.xml](https://github.com/d3/d3-request/blob/master/README.md#xml) encounters an error parsing XML, this error is now reported to error listeners rather than returning a null response. - -The [d3.request](https://github.com/d3/d3-request/blob/master/README.md#request), [d3.text](https://github.com/d3/d3-request/blob/master/README.md#text) and [d3.xml](https://github.com/d3/d3-request/blob/master/README.md#xml) methods no longer take an optional mime type as the second argument; use [*request*.mimeType](https://github.com/d3/d3-request/blob/master/README.md#request_mimeType) instead. For example: - -```js -d3.xml("file.svg").mimeType("image/svg+xml").get(function(error, svg) { - … -}); -``` - -With the exception of [d3.html](https://github.com/d3/d3-request/blob/master/README.md#html) and [d3.xml](https://github.com/d3/d3-request/blob/master/README.md#xml), Node is now supported via [node-XMLHttpRequest](https://github.com/driverdan/node-XMLHttpRequest). - -## [Scales (d3-scale)](https://github.com/d3/d3-scale/blob/master/README.md) - -Pursuant to the great namespace flattening: - -* d3.scale.linear ↦ [d3.scaleLinear](https://github.com/d3/d3-scale/blob/master/README.md#scaleLinear) -* d3.scale.sqrt ↦ [d3.scaleSqrt](https://github.com/d3/d3-scale/blob/master/README.md#scaleSqrt) -* d3.scale.pow ↦ [d3.scalePow](https://github.com/d3/d3-scale/blob/master/README.md#scalePow) -* d3.scale.log ↦ [d3.scaleLog](https://github.com/d3/d3-scale/blob/master/README.md#scaleLog) -* d3.scale.quantize ↦ [d3.scaleQuantize](https://github.com/d3/d3-scale/blob/master/README.md#scaleQuantize) -* d3.scale.threshold ↦ [d3.scaleThreshold](https://github.com/d3/d3-scale/blob/master/README.md#scaleThreshold) -* d3.scale.quantile ↦ [d3.scaleQuantile](https://github.com/d3/d3-scale/blob/master/README.md#scaleQuantile) -* d3.scale.identity ↦ [d3.scaleIdentity](https://github.com/d3/d3-scale/blob/master/README.md#scaleIdentity) -* d3.scale.ordinal ↦ [d3.scaleOrdinal](https://github.com/d3/d3-scale/blob/master/README.md#scaleOrdinal) -* d3.time.scale ↦ [d3.scaleTime](https://github.com/d3/d3-scale/blob/master/README.md#scaleTime) -* d3.time.scale.utc ↦ [d3.scaleUtc](https://github.com/d3/d3-scale/blob/master/README.md#scaleUtc) - -Scales now generate ticks in the same order as the domain: if you have a descending domain, you now get descending ticks. This change affects the order of tick elements generated by [axes](#axes-d3-axis). For example: - -```js -d3.scaleLinear().domain([10, 0]).ticks(5); // [10, 8, 6, 4, 2, 0] -``` - -[Log tick formatting](https://github.com/d3/d3-scale/blob/master/README.md#log_tickFormat) now assumes a default *count* of ten, not Infinity, if not specified. Log scales with domains that span many powers (such as from 1e+3 to 1e+29) now return only one [tick](https://github.com/d3/d3-scale/blob/master/README.md#log_ticks) per power rather than returning *base* ticks per power. Non-linear quantitative scales are slightly more accurate. - -You can now control whether an ordinal scale’s domain is implicitly extended when the scale is passed a value that is not already in its domain. By default, [*ordinal*.unknown](https://github.com/d3/d3-scale/blob/master/README.md#ordinal_unknown) is [d3.scaleImplicit](https://github.com/d3/d3-scale/blob/master/README.md#scaleImplicit), causing unknown values to be added to the domain: - -```js -var x = d3.scaleOrdinal() - .domain([0, 1]) - .range(["red", "green", "blue"]); - -x.domain(); // [0, 1] -x(2); // "blue" -x.domain(); // [0, 1, 2] -``` - -By setting *ordinal*.unknown, you instead define the output value for unknown inputs. This is particularly useful for choropleth maps where you want to assign a color to missing data. - -```js -var x = d3.scaleOrdinal() - .domain([0, 1]) - .range(["red", "green", "blue"]) - .unknown(undefined); - -x.domain(); // [0, 1] -x(2); // undefined -x.domain(); // [0, 1] -``` - -The *ordinal*.rangeBands and *ordinal*.rangeRoundBands methods have been replaced with a new subclass of ordinal scale: [band scales](https://github.com/d3/d3-scale/blob/master/README.md#band-scales). The following code in 3.x: - -```js -var x = d3.scale.ordinal() - .domain(["a", "b", "c"]) - .rangeBands([0, width]); -``` - -Is equivalent to this in 4.0: - -```js -var x = d3.scaleBand() - .domain(["a", "b", "c"]) - .range([0, width]); -``` - -The new [*band*.padding](https://github.com/d3/d3-scale/blob/master/README.md#band_padding), [*band*.paddingInner](https://github.com/d3/d3-scale/blob/master/README.md#band_paddingInner) and [*band*.paddingOuter](https://github.com/d3/d3-scale/blob/master/README.md#band_paddingOuter) methods replace the optional arguments to *ordinal*.rangeBands. The new [*band*.bandwidth](https://github.com/d3/d3-scale/blob/master/README.md#band_bandwidth) and [*band*.step](https://github.com/d3/d3-scale/blob/master/README.md#band_step) methods replace *ordinal*.rangeBand. There’s also a new [*band*.align](https://github.com/d3/d3-scale/blob/master/README.md#band_align) method which you can use to control how the extra space outside the bands is distributed, say to shift columns closer to the *y*-axis. - -Similarly, the *ordinal*.rangePoints and *ordinal*.rangeRoundPoints methods have been replaced with a new subclass of ordinal scale: [point scales](https://github.com/d3/d3-scale/blob/master/README.md#point-scales). The following code in 3.x: - -```js -var x = d3.scale.ordinal() - .domain(["a", "b", "c"]) - .rangePoints([0, width]); -``` - -Is equivalent to this in 4.0: - -```js -var x = d3.scalePoint() - .domain(["a", "b", "c"]) - .range([0, width]); -``` - -The new [*point*.padding](https://github.com/d3/d3-scale/blob/master/README.md#point_padding) method replaces the optional *padding* argument to *ordinal*.rangePoints. Like *ordinal*.rangeBand with *ordinal*.rangePoints, the [*point*.bandwidth](https://github.com/d3/d3-scale/blob/master/README.md#point_bandwidth) method always returns zero; a new [*point*.step](https://github.com/d3/d3-scale/blob/master/README.md#point_step) method returns the interval between adjacent points. - -The [ordinal scale constructor](https://github.com/d3/d3-scale/blob/master/README.md#ordinal-scales) now takes an optional *range* for a shorter alternative to [*ordinal*.range](https://github.com/d3/d3-scale/blob/master/README.md#ordinal_range). This is especially useful now that the categorical color scales have been changed to simple arrays of colors rather than specialized ordinal scale constructors: - -* d3.scale.category10 ↦ [d3.schemeCategory10](https://github.com/d3/d3-scale/blob/master/README.md#schemeCategory10) -* d3.scale.category20 ↦ [d3.schemeCategory20](https://github.com/d3/d3-scale/blob/master/README.md#schemeCategory20) -* d3.scale.category20b ↦ [d3.schemeCategory20b](https://github.com/d3/d3-scale/blob/master/README.md#schemeCategory20b) -* d3.scale.category20c ↦ [d3.schemeCategory20c](https://github.com/d3/d3-scale/blob/master/README.md#schemeCategory20c) - -The following code in 3.x: - -```js -var color = d3.scale.category10(); -``` - -Is equivalent to this in 4.0: - -```js -var color = d3.scaleOrdinal(d3.schemeCategory10); -``` - -[Sequential scales](https://github.com/d3/d3-scale/blob/master/README.md#scaleSequential), are a new class of scales with a fixed output [interpolator](https://github.com/d3/d3-scale/blob/master/README.md#sequential_interpolator) instead of a [range](https://github.com/d3/d3-scale/blob/master/README.md#continuous_range). Typically these scales are used to implement continuous sequential or diverging color schemes. Inspired by Matplotlib’s new [perceptually-motived colormaps](https://bids.github.io/colormap/), 4.0 now features [viridis](https://github.com/d3/d3-scale/blob/master/README.md#interpolateViridis), [inferno](https://github.com/d3/d3-scale/blob/master/README.md#interpolateInferno), [magma](https://github.com/d3/d3-scale/blob/master/README.md#interpolateMagma), [plasma](https://github.com/d3/d3-scale/blob/master/README.md#interpolatePlasma) interpolators for use with sequential scales. Using [d3.quantize](https://github.com/d3/d3-interpolate/blob/master/README.md#quantize), these interpolators can also be applied to [quantile](https://github.com/d3/d3-scale/blob/master/README.md#quantile-scales), [quantize](https://github.com/d3/d3-scale/blob/master/README.md#quantize-scales) and [threshold](https://github.com/d3/d3-scale/blob/master/README.md#threshold-scales) scales. - -[viridis](https://github.com/d3/d3-scale/blob/master/README.md#interpolateViridis) -[inferno](https://github.com/d3/d3-scale/blob/master/README.md#interpolateInferno) -[magma](https://github.com/d3/d3-scale/blob/master/README.md#interpolateMagma) -[plasma](https://github.com/d3/d3-scale/blob/master/README.md#interpolatePlasma) - -4.0 also ships new Cubehelix schemes, including [Dave Green’s default](https://github.com/d3/d3-scale/blob/master/README.md#interpolateCubehelixDefault) and a [cyclical rainbow](https://github.com/d3/d3-scale/blob/master/README.md#interpolateRainbow) inspired by [Matteo Niccoli](https://mycarta.wordpress.com/2013/02/21/perceptual-rainbow-palette-the-method/): - -[cubehelix](https://github.com/d3/d3-scale/blob/master/README.md#interpolateCubehelixDefault) -[rainbow](https://github.com/d3/d3-scale/blob/master/README.md#interpolateRainbow) -[warm](https://github.com/d3/d3-scale/blob/master/README.md#interpolateWarm) -[cool](https://github.com/d3/d3-scale/blob/master/README.md#interpolateCool) - -For even more sequential and categorical color schemes, see [d3-scale-chromatic](https://github.com/d3/d3-scale-chromatic). - -For an introduction to scales, see [Introducing d3-scale](https://medium.com/@mbostock/introducing-d3-scale-61980c51545f). - -## [Selections (d3-selection)](https://github.com/d3/d3-selection/blob/master/README.md) - -Selections no longer subclass Array using [prototype chain injection](http://perfectionkills.com/how-ecmascript-5-still-does-not-allow-to-subclass-an-array/#wrappers_prototype_chain_injection); they are now plain objects, improving performance. The internal fields (*selection*.\_groups, *selection*.\_parents) are private; please use the documented public API to manipulate selections. The new [*selection*.nodes](https://github.com/d3/d3-selection/blob/master/README.md#selection_nodes) method generates an array of all nodes in a selection. - -Selections are now immutable: the elements and parents in a selection never change. (The elements’ attributes and content will of course still be modified!) The [*selection*.sort](https://github.com/d3/d3-selection/blob/master/README.md#selection_sort) and [*selection*.data](https://github.com/d3/d3-selection/blob/master/README.md#selection_data) methods now return new selections rather than modifying the selection in-place. In addition, [*selection*.append](https://github.com/d3/d3-selection/blob/master/README.md#selection_append) no longer merges entering nodes into the update selection; use [*selection*.merge](https://github.com/d3/d3-selection/blob/master/README.md#selection_merge) to combine enter and update after a data join. For example, the following [general update pattern](https://bl.ocks.org/mbostock/a8a5baa4c4a470cda598) in 3.x: - -```js -var circle = svg.selectAll("circle").data(data) // UPDATE - .style("fill", "blue"); - -circle.exit().remove(); // EXIT - -circle.enter().append("circle") // ENTER; modifies UPDATE! 🌶 - .style("fill", "green"); - -circle // ENTER + UPDATE - .style("stroke", "black"); -``` - -Would be rewritten in 4.0 as: - -```js -var circle = svg.selectAll("circle").data(data) // UPDATE - .style("fill", "blue"); - -circle.exit().remove(); // EXIT - -circle.enter().append("circle") // ENTER - .style("fill", "green") - .merge(circle) // ENTER + UPDATE - .style("stroke", "black"); -``` - -This change is discussed further in [What Makes Software Good](https://medium.com/@mbostock/what-makes-software-good-943557f8a488). - -In 3.x, the [*selection*.enter](https://github.com/d3/d3-selection/blob/master/README.md#selection_enter) and [*selection*.exit](https://github.com/d3/d3-selection/blob/master/README.md#selection_exit) methods were undefined until you called *selection*.data, resulting in a TypeError if you attempted to access them. In 4.0, now they simply return the empty selection if the selection has not been joined to data. - -In 3.x, [*selection*.append](https://github.com/d3/d3-selection/blob/master/README.md#selection_append) would always append the new element as the last child of its parent. A little-known trick was to use [*selection*.insert](https://github.com/d3/d3-selection/blob/master/README.md#selection_insert) without specifying a *before* selector when entering nodes, causing the entering nodes to be inserted before the following element in the update selection. In 4.0, this is now the default behavior of *selection*.append; if you do not specify a *before* selector to *selection*.insert, the inserted element is appended as the last child. This change makes the general update pattern preserve the relative order of elements and data. For example, given the following DOM: - -```html -
a
-
b
-
f
-``` - -And the following code: - -```js -var div = d3.select("body").selectAll("div") - .data(["a", "b", "c", "d", "e", "f"], function(d) { return d || this.textContent; }); - -div.enter().append("div") - .text(function(d) { return d; }); -``` - -The resulting DOM will be: - -```html -
a
-
b
-
c
-
d
-
e
-
f
-``` - -Thus, the entering *c*, *d* and *e* are inserted before *f*, since *f* is the following element in the update selection. Although this behavior is sufficient to preserve order if the new data’s order is stable, if the data changes order, you must still use [*selection*.order](https://github.com/d3/d3-selection/blob/master/README.md#selection_order) to reorder elements. - -There is now only one class of selection. 3.x implemented enter selections using a special class with different behavior for *enter*.append and *enter*.select; a consequence of this design was that enter selections in 3.x lacked [certain methods](https://github.com/d3/d3/issues/2043). In 4.0, enter selections are simply normal selections; they have the same methods and the same behavior. Placeholder [enter nodes](https://github.com/d3/d3-selection/blob/master/src/selection/enter.js) now implement [*node*.appendChild](https://developer.mozilla.org/en-US/docs/Web/API/Node/appendChild), [*node*.insertBefore](https://developer.mozilla.org/en-US/docs/Web/API/Node/insertBefore), [*node*.querySelector](https://developer.mozilla.org/en-US/docs/Web/API/Element/querySelector), and [*node*.querySelectorAll](https://developer.mozilla.org/en-US/docs/Web/API/Element/querySelectorAll). - -The [*selection*.data](https://github.com/d3/d3-selection/blob/master/README.md#selection_data) method has been changed slightly with respect to duplicate keys. In 3.x, if multiple data had the same key, the duplicate data would be ignored and not included in enter, update or exit; in 4.0 the duplicate data is always put in the enter selection. In both 3.x and 4.0, if multiple elements have the same key, the duplicate elements are put in the exit selection. Thus, 4.0’s behavior is now symmetric for enter and exit, and the general update pattern will now produce a DOM that matches the data even if there are duplicate keys. - -Selections have several new methods! Use [*selection*.raise](https://github.com/d3/d3-selection/blob/master/README.md#selection_raise) to move the selected elements to the front of their siblings, so that they are drawn on top; use [*selection*.lower](https://github.com/d3/d3-selection/blob/master/README.md#selection_lower) to move them to the back. Use [*selection*.dispatch](https://github.com/d3/d3-selection/blob/master/README.md#selection_dispatch) to dispatch a [custom event](https://developer.mozilla.org/en-US/docs/Web/API/CustomEvent) to event listeners. - -When called in getter mode, [*selection*.data](https://github.com/d3/d3-selection/blob/master/README.md#selection_data) now returns the data for all elements in the selection, rather than just the data for the first group of elements. The [*selection*.call](https://github.com/d3/d3-selection/blob/master/README.md#selection_call) method no longer sets the `this` context when invoking the specified function; the *selection* is passed as the first argument to the function, so use that. The [*selection*.on](https://github.com/d3/d3-selection/blob/master/README.md#selection_on) method now accepts multiple whitespace-separated typenames, so you can add or remove multiple listeners simultaneously. For example: - -```js -selection.on("mousedown touchstart", function() { - console.log(d3.event.type); -}); -``` - -The arguments passed to callback functions has changed slightly in 4.0 to be more consistent. The standard arguments are the element’s datum (*d*), the element’s index (*i*), and the element’s group (*nodes*), with *this* as the element. The slight exception to this convention is *selection*.data, which is evaluated for each group rather than each element; it is passed the group’s parent datum (*d*), the group index (*i*), and the selection’s parents (*parents*), with *this* as the group’s parent. - -The new [d3.local](https://github.com/d3/d3-selection/blob/master/README.md#local-variables) provides a mechanism for defining [local variables](https://bl.ocks.org/mbostock/e1192fe405703d8321a5187350910e08): state that is bound to DOM elements, and available to any descendant element. This can be a convenient alternative to using [*selection*.each](https://github.com/d3/d3-selection/blob/master/README.md#selection_each) or storing local state in data. - -The d3.ns.prefix namespace prefix map has been renamed to [d3.namespaces](https://github.com/d3/d3-selection/blob/master/README.md#namespaces), and the d3.ns.qualify method has been renamed to [d3.namespace](https://github.com/d3/d3-selection/blob/master/README.md#namespace). Several new low-level methods are now available, as well. [d3.matcher](https://github.com/d3/d3-selection/blob/master/README.md#matcher) is used internally by [*selection*.filter](https://github.com/d3/d3-selection/blob/master/README.md#selection_filter); [d3.selector](https://github.com/d3/d3-selection/blob/master/README.md#selector) is used by [*selection*.select](https://github.com/d3/d3-selection/blob/master/README.md#selection_select); [d3.selectorAll](https://github.com/d3/d3-selection/blob/master/README.md#selectorAll) is used by [*selection*.selectAll](https://github.com/d3/d3-selection/blob/master/README.md#selection_selectAll); [d3.creator](https://github.com/d3/d3-selection/blob/master/README.md#creator) is used by [*selection*.append](https://github.com/d3/d3-selection/blob/master/README.md#selection_append) and [*selection*.insert](https://github.com/d3/d3-selection/blob/master/README.md#selection_insert). The new [d3.window](https://github.com/d3/d3-selection/blob/master/README.md#window) returns the owner window for a given element, window or document. The new [d3.customEvent](https://github.com/d3/d3-selection/blob/master/README.md#customEvent) temporarily sets [d3.event](https://github.com/d3/d3-selection/blob/master/README.md#event) while invoking a function, allowing you to implement controls which dispatch custom events; this is used by [d3-drag](https://github.com/d3/d3-drag), [d3-zoom](https://github.com/d3/d3-zoom) and [d3-brush](https://github.com/d3/d3-brush). - -For the sake of parsimony, the multi-value methods—where you pass an object to set multiple attributes, styles or properties simultaneously—have been extracted to [d3-selection-multi](https://github.com/d3/d3-selection-multi) and are no longer part of the default bundle. The multi-value map methods have also been renamed to plural form to reduce overload: [*selection*.attrs](https://github.com/d3/d3-selection-multi/blob/master/README.md#selection_attrs), [*selection*.styles](https://github.com/d3/d3-selection-multi/blob/master/README.md#selection_styles) and [*selection*.properties](https://github.com/d3/d3-selection-multi/blob/master/README.md#selection_properties). - -## [Shapes (d3-shape)](https://github.com/d3/d3-shape/blob/master/README.md) - -Pursuant to the great namespace flattening: - -* d3.svg.line ↦ [d3.line](https://github.com/d3/d3-shape/blob/master/README.md#lines) -* d3.svg.line.radial ↦ [d3.radialLine](https://github.com/d3/d3-shape/blob/master/README.md#radialLine) -* d3.svg.area ↦ [d3.area](https://github.com/d3/d3-shape/blob/master/README.md#areas) -* d3.svg.area.radial ↦ [d3.radialArea](https://github.com/d3/d3-shape/blob/master/README.md#radialArea) -* d3.svg.arc ↦ [d3.arc](https://github.com/d3/d3-shape/blob/master/README.md#arcs) -* d3.svg.symbol ↦ [d3.symbol](https://github.com/d3/d3-shape/blob/master/README.md#symbols) -* d3.svg.symbolTypes ↦ [d3.symbolTypes](https://github.com/d3/d3-shape/blob/master/README.md#symbolTypes) -* d3.layout.pie ↦ [d3.pie](https://github.com/d3/d3-shape/blob/master/README.md#pies) -* d3.layout.stack ↦ [d3.stack](https://github.com/d3/d3-shape/blob/master/README.md#stacks) -* d3.svg.diagonal ↦ REMOVED (see [d3/d3-shape#27](https://github.com/d3/d3-shape/issues/27)) -* d3.svg.diagonal.radial ↦ REMOVED - -Shapes are no longer limited to SVG; they can now render to Canvas! Shape generators now support an optional *context*: given a [CanvasRenderingContext2D](https://developer.mozilla.org/en-US/docs/Web/API/CanvasRenderingContext2D), you can render a shape as a canvas path to be filled or stroked. For example, a [canvas pie chart](https://bl.ocks.org/mbostock/8878e7fd82034f1d63cf) might use an arc generator: - -```js -var arc = d3.arc() - .outerRadius(radius - 10) - .innerRadius(0) - .context(context); -``` - -To render an arc for a given datum *d*: - -```js -context.beginPath(); -arc(d); -context.fill(); -``` - -See [*line*.context](https://github.com/d3/d3-shape/blob/master/README.md#line_context), [*area*.context](https://github.com/d3/d3-shape/blob/master/README.md#area_context) and [*arc*.context](https://github.com/d3/d3-shape/blob/master/README.md#arc_context) for more. Under the hood, shapes use [d3-path](#paths-d3-path) to serialize canvas path methods to SVG path data when the context is null; thus, shapes are optimized for rendering to canvas. You can also now derive lines from areas. The line shares most of the same accessors, such as [*line*.defined](https://github.com/d3/d3-shape/blob/master/README.md#line_defined) and [*line*.curve](https://github.com/d3/d3-shape/blob/master/README.md#line_curve), with the area from which it is derived. For example, to render the topline of an area, use [*area*.lineY1](https://github.com/d3/d3-shape/blob/master/README.md#area_lineY1); for the baseline, use [*area*.lineY0](https://github.com/d3/d3-shape/blob/master/README.md#area_lineY0). - -4.0 introduces a new curve API for specifying how line and area shapes interpolate between data points. The *line*.interpolate and *area*.interpolate methods have been replaced with [*line*.curve](https://github.com/d3/d3-shape/blob/master/README.md#line_curve) and [*area*.curve](https://github.com/d3/d3-shape/blob/master/README.md#area_curve). Curves are implemented using the [curve interface](https://github.com/d3/d3-shape/blob/master/README.md#custom-curves) rather than as a function that returns an SVG path data string; this allows curves to render to either SVG or Canvas. In addition, *line*.curve and *area*.curve now take a function which instantiates a curve for a given *context*, rather than a string. The full list of equivalents: - -* linear ↦ [d3.curveLinear](https://github.com/d3/d3-shape/blob/master/README.md#curveLinear) -* linear-closed ↦ [d3.curveLinearClosed](https://github.com/d3/d3-shape/blob/master/README.md#curveLinearClosed) -* step ↦ [d3.curveStep](https://github.com/d3/d3-shape/blob/master/README.md#curveStep) -* step-before ↦ [d3.curveStepBefore](https://github.com/d3/d3-shape/blob/master/README.md#curveStepBefore) -* step-after ↦ [d3.curveStepAfter](https://github.com/d3/d3-shape/blob/master/README.md#curveStepAfter) -* basis ↦ [d3.curveBasis](https://github.com/d3/d3-shape/blob/master/README.md#curveBasis) -* basis-open ↦ [d3.curveBasisOpen](https://github.com/d3/d3-shape/blob/master/README.md#curveBasisOpen) -* basis-closed ↦ [d3.curveBasisClosed](https://github.com/d3/d3-shape/blob/master/README.md#curveBasisClosed) -* bundle ↦ [d3.curveBundle](https://github.com/d3/d3-shape/blob/master/README.md#curveBundle) -* cardinal ↦ [d3.curveCardinal](https://github.com/d3/d3-shape/blob/master/README.md#curveCardinal) -* cardinal-open ↦ [d3.curveCardinalOpen](https://github.com/d3/d3-shape/blob/master/README.md#curveCardinalOpen) -* cardinal-closed ↦ [d3.curveCardinalClosed](https://github.com/d3/d3-shape/blob/master/README.md#curveCardinalClosed) -* monotone ↦ [d3.curveMonotoneX](https://github.com/d3/d3-shape/blob/master/README.md#curveMonotoneX) - -But that’s not all! 4.0 now provides parameterized Catmull–Rom splines as proposed by [Yuksel *et al.*](http://www.cemyuksel.com/research/catmullrom_param/). These are available as [d3.curveCatmullRom](https://github.com/d3/d3-shape/blob/master/README.md#curveCatmullRom), [d3.curveCatmullRomClosed](https://github.com/d3/d3-shape/blob/master/README.md#curveCatmullRomClosed) and [d3.curveCatmullRomOpen](https://github.com/d3/d3-shape/blob/master/README.md#curveCatmullRomOpen). - -catmullRom -catmullRomOpen -catmullRomClosed - -Each curve type can define its own named parameters, replacing *line*.tension and *area*.tension. For example, Catmull–Rom splines are parameterized using [*catmullRom*.alpha](https://github.com/d3/d3-shape/blob/master/README.md#curveCatmullRom_alpha) and defaults to 0.5, which corresponds to a centripetal spline that avoids self-intersections and overshoot. For a uniform Catmull–Rom spline instead: - -```js -var line = d3.line() - .curve(d3.curveCatmullRom.alpha(0)); -``` - -4.0 fixes the interpretation of the cardinal spline *tension* parameter, which is now specified as [*cardinal*.tension](https://github.com/d3/d3-shape/blob/master/README.md#curveCardinal_tension) and defaults to zero for a uniform Catmull–Rom spline; a tension of one produces a linear curve. The first and last segments of basis and cardinal curves have also been fixed! The undocumented *interpolate*.reverse field has been removed. Curves can define different behavior for toplines and baselines by counting the sequence of [*curve*.lineStart](https://github.com/d3/d3-shape/blob/master/README.md#curve_lineStart) within [*curve*.areaStart](https://github.com/d3/d3-shape/blob/master/README.md#curve_areaStart). See the [d3.curveStep implementation](https://github.com/d3/d3-shape/blob/master/src/curve/step.js) for an example. - -4.0 fixes numerous bugs in the monotone curve implementation, and introduces [d3.curveMonotoneY](https://github.com/d3/d3-shape/blob/master/README.md#curveMonotoneY); this is like d3.curveMonotoneX, except it requires that the input points are monotone in *y* rather than *x*, such as for a vertically-oriented line chart. The new [d3.curveNatural](https://github.com/d3/d3-shape/blob/master/README.md#curveNatural) produces a [natural cubic spline](http://mathworld.wolfram.com/CubicSpline.html). The default [β](https://github.com/d3/d3-shape/blob/master/README.md#bundle_beta) for [d3.curveBundle](https://github.com/d3/d3-shape/blob/master/README.md#curveBundle) is now 0.85, rather than 0.7, matching the values used by [Holten](https://www.win.tue.nl/vis1/home/dholten/papers/bundles_infovis.pdf). 4.0 also has a more robust implementation of arc padding; see [*arc*.padAngle](https://github.com/d3/d3-shape/blob/master/README.md#arc_padAngle) and [*arc*.padRadius](https://github.com/d3/d3-shape/blob/master/README.md#arc_padRadius). - -4.0 introduces a new symbol type API. Symbol types are passed to [*symbol*.type](https://github.com/d3/d3-shape/blob/master/README.md#symbol_type) in place of strings. The equivalents are: - -* circle ↦ [d3.symbolCircle](https://github.com/d3/d3-shape/blob/master/README.md#symbolCircle) -* cross ↦ [d3.symbolCross](https://github.com/d3/d3-shape/blob/master/README.md#symbolCross) -* diamond ↦ [d3.symbolDiamond](https://github.com/d3/d3-shape/blob/master/README.md#symbolDiamond) -* square ↦ [d3.symbolSquare](https://github.com/d3/d3-shape/blob/master/README.md#symbolSquare) -* triangle-down ↦ REMOVED -* triangle-up ↦ [d3.symbolTriangle](https://github.com/d3/d3-shape/blob/master/README.md#symbolTriangle) -* ADDED ↦ [d3.symbolStar](https://github.com/d3/d3-shape/blob/master/README.md#symbolStar) -* ADDED ↦ [d3.symbolWye](https://github.com/d3/d3-shape/blob/master/README.md#symbolWye) - -The full set of symbol types is now: - - - -Lastly, 4.0 overhauls the stack layout API, replacing d3.layout.stack with [d3.stack](https://github.com/d3/d3-shape/blob/master/README.md#stacks). The stack generator no longer needs an *x*-accessor. In addition, the API has been simplified: the *stack* generator now accepts tabular input, such as this array of objects: - -```js -var data = [ - {month: new Date(2015, 0, 1), apples: 3840, bananas: 1920, cherries: 960, dates: 400}, - {month: new Date(2015, 1, 1), apples: 1600, bananas: 1440, cherries: 960, dates: 400}, - {month: new Date(2015, 2, 1), apples: 640, bananas: 960, cherries: 640, dates: 400}, - {month: new Date(2015, 3, 1), apples: 320, bananas: 480, cherries: 640, dates: 400} -]; -``` - -To generate the stack layout, first define a stack generator, and then apply it to the data: - -```js -var stack = d3.stack() - .keys(["apples", "bananas", "cherries", "dates"]) - .order(d3.stackOrderNone) - .offset(d3.stackOffsetNone); - -var series = stack(data); -``` - -The resulting array has one element per *series*. Each series has one point per month, and each point has a lower and upper value defining the baseline and topline: - -```js -[ - [[ 0, 3840], [ 0, 1600], [ 0, 640], [ 0, 320]], // apples - [[3840, 5760], [1600, 3040], [ 640, 1600], [ 320, 800]], // bananas - [[5760, 6720], [3040, 4000], [1600, 2240], [ 800, 1440]], // cherries - [[6720, 7120], [4000, 4400], [2240, 2640], [1440, 1840]], // dates -] -``` - -Each series in then typically passed to an [area generator](https://github.com/d3/d3-shape/blob/master/README.md#areas) to render an area chart, or used to construct rectangles for a bar chart. Stack generators no longer modify the input data, so *stack*.out has been removed. - -For an introduction to shapes, see [Introducing d3-shape](https://medium.com/@mbostock/introducing-d3-shape-73f8367e6d12). - -## [Time Formats (d3-time-format)](https://github.com/d3/d3-time-format/blob/master/README.md) - -Pursuant to the great namespace flattening, the format constructors have new names: - -* d3.time.format ↦ [d3.timeFormat](https://github.com/d3/d3-time-format/blob/master/README.md#timeFormat) -* d3.time.format.utc ↦ [d3.utcFormat](https://github.com/d3/d3-time-format/blob/master/README.md#utcFormat) -* d3.time.format.iso ↦ [d3.isoFormat](https://github.com/d3/d3-time-format/blob/master/README.md#isoFormat) - -The *format*.parse method has also been removed in favor of separate [d3.timeParse](https://github.com/d3/d3-time-format/blob/master/README.md#timeParse), [d3.utcParse](https://github.com/d3/d3-time-format/blob/master/README.md#utcParse) and [d3.isoParse](https://github.com/d3/d3-time-format/blob/master/README.md#isoParse) parser constructors. Thus, this code in 3.x: - -```js -var parseTime = d3.time.format("%c").parse; -``` - -Can be rewritten in 4.0 as: - -```js -var parseTime = d3.timeParse("%c"); -``` - -The multi-scale time format d3.time.format.multi has been replaced by [d3.scaleTime](https://github.com/d3/d3-scale/blob/master/README.md#scaleTime)’s [tick format](https://github.com/d3/d3-scale/blob/master/README.md#time_tickFormat). Time formats now coerce inputs to dates, and time parsers coerce inputs to strings. The `%Z` directive now allows more flexible parsing of time zone offsets, such as `-0700`, `-07:00`, `-07`, and `Z`. The `%p` directive is now parsed correctly when the locale’s period name is longer than two characters (*e.g.*, “a.m.”). - -The default U.S. English locale now uses 12-hour time and a more concise representation of the date. This aligns with local convention and is consistent with [*date*.toLocaleString](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleString) in Chrome, Firefox and Node: - -```js -var now = new Date; -d3.timeFormat("%c")(new Date); // "6/23/2016, 2:01:33 PM" -d3.timeFormat("%x")(new Date); // "6/23/2016" -d3.timeFormat("%X")(new Date); // "2:01:38 PM" -``` - -You can now set the default locale using [d3.timeFormatDefaultLocale](https://github.com/d3/d3-time-format/blob/master/README.md#timeFormatDefaultLocale)! The locales are published as [JSON](https://github.com/d3/d3-request/blob/master/README.md#json) to [npm](https://unpkg.com/d3-time-format/locale/). - -The performance of time formatting and parsing has been improved, and the UTC formatter and parser have a cleaner implementation (that avoids temporarily overriding the Date global). - -## [Time Intervals (d3-time)](https://github.com/d3/d3-time/blob/master/README.md) - -Pursuant to the great namespace flattening, the local time intervals have been renamed: - -* ADDED ↦ [d3.timeMillisecond](https://github.com/d3/d3-time/blob/master/README.md#timeMillisecond) -* d3.time.second ↦ [d3.timeSecond](https://github.com/d3/d3-time/blob/master/README.md#timeSecond) -* d3.time.minute ↦ [d3.timeMinute](https://github.com/d3/d3-time/blob/master/README.md#timeMinute) -* d3.time.hour ↦ [d3.timeHour](https://github.com/d3/d3-time/blob/master/README.md#timeHour) -* d3.time.day ↦ [d3.timeDay](https://github.com/d3/d3-time/blob/master/README.md#timeDay) -* d3.time.sunday ↦ [d3.timeSunday](https://github.com/d3/d3-time/blob/master/README.md#timeSunday) -* d3.time.monday ↦ [d3.timeMonday](https://github.com/d3/d3-time/blob/master/README.md#timeMonday) -* d3.time.tuesday ↦ [d3.timeTuesday](https://github.com/d3/d3-time/blob/master/README.md#timeTuesday) -* d3.time.wednesday ↦ [d3.timeWednesday](https://github.com/d3/d3-time/blob/master/README.md#timeWednesday) -* d3.time.thursday ↦ [d3.timeThursday](https://github.com/d3/d3-time/blob/master/README.md#timeThursday) -* d3.time.friday ↦ [d3.timeFriday](https://github.com/d3/d3-time/blob/master/README.md#timeFriday) -* d3.time.saturday ↦ [d3.timeSaturday](https://github.com/d3/d3-time/blob/master/README.md#timeSaturday) -* d3.time.week ↦ [d3.timeWeek](https://github.com/d3/d3-time/blob/master/README.md#timeWeek) -* d3.time.month ↦ [d3.timeMonth](https://github.com/d3/d3-time/blob/master/README.md#timeMonth) -* d3.time.year ↦ [d3.timeYear](https://github.com/d3/d3-time/blob/master/README.md#timeYear) -

-The behavior of [*interval*.range](https://github.com/d3/d3-time/blob/master/README.md#interval_range) (and the convenience aliases such as [d3.timeDays](https://github.com/d3/d3-time/blob/master/README.md#timeDays)) has been changed when *step* is greater than one. Rather than filtering the returned dates using the field number, *interval*.range now behaves like [d3.range](https://github.com/d3/d3-array/blob/master/README.md#range): it simply skips, returning every *step*th date. For example, the following code in 3.x returns only odd days of the month: - -```js -d3.time.days(new Date(2016, 4, 28), new Date(2016, 5, 5), 2); -// [Sun May 29 2016 00:00:00 GMT-0700 (PDT), -// Tue May 31 2016 00:00:00 GMT-0700 (PDT), -// Wed Jun 01 2016 00:00:00 GMT-0700 (PDT), -// Fri Jun 03 2016 00:00:00 GMT-0700 (PDT)] -``` - -Note the returned array of dates does not start on the *start* date because May 28 is even. Also note that May 31 and June 1 are one day apart, not two! The behavior of d3.timeDays in 4.0 is probably closer to what you expect: - -```js -d3.timeDays(new Date(2016, 4, 28), new Date(2016, 5, 5), 2); -// [Sat May 28 2016 00:00:00 GMT-0700 (PDT), -// Mon May 30 2016 00:00:00 GMT-0700 (PDT), -// Wed Jun 01 2016 00:00:00 GMT-0700 (PDT), -// Fri Jun 03 2016 00:00:00 GMT-0700 (PDT)] -``` - -If you want a filtered view of a time interval (say to guarantee that two overlapping ranges are consistent, such as when generating [time scale ticks](https://github.com/d3/d3-scale/blob/master/README.md#time_ticks)), you can use the new [*interval*.every](https://github.com/d3/d3-time/blob/master/README.md#interval_every) method or its more general cousin [*interval*.filter](https://github.com/d3/d3-time/blob/master/README.md#interval_filter): - -```js -d3.timeDay.every(2).range(new Date(2016, 4, 28), new Date(2016, 5, 5)); -// [Sun May 29 2016 00:00:00 GMT-0700 (PDT), -// Tue May 31 2016 00:00:00 GMT-0700 (PDT), -// Wed Jun 01 2016 00:00:00 GMT-0700 (PDT), -// Fri Jun 03 2016 00:00:00 GMT-0700 (PDT)] -``` - -Time intervals now expose an [*interval*.count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) method for counting the number of interval boundaries after a *start* date and before or equal to an *end* date. This replaces d3.time.dayOfYear and related methods in 3.x. For example, this code in 3.x: - -```js -var now = new Date; -d3.time.dayOfYear(now); // 165 -``` - -Can be rewritten in 4.0 as: - -```js -var now = new Date; -d3.timeDay.count(d3.timeYear(now), now); // 165 -``` - -Likewise, in place of 3.x’s d3.time.weekOfYear, in 4.0 you would say: - -```js -d3.timeWeek.count(d3.timeYear(now), now); // 24 -``` - -The new *interval*.count is of course more general. For example, you can use it to compute hour-of-week for a heatmap: - -```js -d3.timeHour.count(d3.timeWeek(now), now); // 64 -``` - -Here are all the equivalences from 3.x to 4.0: - -* d3.time.dayOfYear ↦ [d3.timeDay](https://github.com/d3/d3-time/blob/master/README.md#timeDay).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.sundayOfYear ↦ [d3.timeSunday](https://github.com/d3/d3-time/blob/master/README.md#timeSunday).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.mondayOfYear ↦ [d3.timeMonday](https://github.com/d3/d3-time/blob/master/README.md#timeMonday).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.tuesdayOfYear ↦ [d3.timeTuesday](https://github.com/d3/d3-time/blob/master/README.md#timeTuesday).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.wednesdayOfYear ↦ [d3.timeWednesday](https://github.com/d3/d3-time/blob/master/README.md#timeWednesday).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.thursdayOfYear ↦ [d3.timeThursday](https://github.com/d3/d3-time/blob/master/README.md#timeThursday).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.fridayOfYear ↦ [d3.timeFriday](https://github.com/d3/d3-time/blob/master/README.md#timeFriday).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.saturdayOfYear ↦ [d3.timeSaturday](https://github.com/d3/d3-time/blob/master/README.md#timeSaturday).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.weekOfYear ↦ [d3.timeWeek](https://github.com/d3/d3-time/blob/master/README.md#timeWeek).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.dayOfYear.utc ↦ [d3.utcDay](https://github.com/d3/d3-time/blob/master/README.md#utcDay).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.sundayOfYear.utc ↦ [d3.utcSunday](https://github.com/d3/d3-time/blob/master/README.md#utcSunday).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.mondayOfYear.utc ↦ [d3.utcMonday](https://github.com/d3/d3-time/blob/master/README.md#utcMonday).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.tuesdayOfYear.utc ↦ [d3.utcTuesday](https://github.com/d3/d3-time/blob/master/README.md#utcTuesday).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.wednesdayOfYear.utc ↦ [d3.utcWednesday](https://github.com/d3/d3-time/blob/master/README.md#utcWednesday).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.thursdayOfYear.utc ↦ [d3.utcThursday](https://github.com/d3/d3-time/blob/master/README.md#utcThursday).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.fridayOfYear.utc ↦ [d3.utcFriday](https://github.com/d3/d3-time/blob/master/README.md#utcFriday).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.saturdayOfYear.utc ↦ [d3.utcSaturday](https://github.com/d3/d3-time/blob/master/README.md#utcSaturday).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) -* d3.time.weekOfYear.utc ↦ [d3.utcWeek](https://github.com/d3/d3-time/blob/master/README.md#utcWeek).[count](https://github.com/d3/d3-time/blob/master/README.md#interval_count) - -D3 4.0 now also lets you define custom time intervals using [d3.timeInterval](https://github.com/d3/d3-time/blob/master/README.md#timeInterval). The [d3.timeYear](https://github.com/d3/d3-time/blob/master/README.md#timeYear), [d3.utcYear](https://github.com/d3/d3-time/blob/master/README.md#utcYear), [d3.timeMillisecond](https://github.com/d3/d3-time/blob/master/README.md#timeMillisecond) and [d3.utcMillisecond](https://github.com/d3/d3-time/blob/master/README.md#utcMillisecond) intervals have optimized implementations of [*interval*.every](https://github.com/d3/d3-time/blob/master/README.md#interval_every), which is necessary to generate time ticks for very large or very small domains efficiently. More generally, the performance of time intervals has been improved, and time intervals now do a better job with respect to daylight savings in various locales. - -## [Timers (d3-timer)](https://github.com/d3/d3-timer/blob/master/README.md) - -In D3 3.x, the only way to stop a timer was for its callback to return true. For example, this timer stops after one second: - -```js -d3.timer(function(elapsed) { - console.log(elapsed); - return elapsed >= 1000; -}); -``` - -In 4.0, use [*timer*.stop](https://github.com/d3/d3-timer/blob/master/README.md#timer_stop) instead: - -```js -var t = d3.timer(function(elapsed) { - console.log(elapsed); - if (elapsed >= 1000) { - t.stop(); - } -}); -``` - -The primary benefit of *timer*.stop is that timers are not required to self-terminate: they can be stopped externally, allowing for the immediate and synchronous disposal of associated resources, and the separation of concerns. The above is equivalent to: - -```js -var t = d3.timer(function(elapsed) { - console.log(elapsed); -}); - -d3.timeout(function() { - t.stop(); -}, 1000); -``` - -This improvement extends to [d3-transition](#transitions-d3-transition): now when a transition is interrupted, its resources are immediately freed rather than having to wait for transition to start. - -4.0 also introduces a new [*timer*.restart](https://github.com/d3/d3-timer/blob/master/README.md#timer_restart) method for restarting timers, for replacing the callback of a running timer, or for changing its delay or reference time. Unlike *timer*.stop followed by [d3.timer](https://github.com/d3/d3-timer/blob/master/README.md#timer), *timer*.restart maintains the invocation priority of an existing timer: it guarantees that the order of invocation of active timers remains the same. The d3.timer.flush method has been renamed to [d3.timerFlush](https://github.com/d3/d3-timer/blob/master/README.md#timerFlush). - -Some usage patterns in D3 3.x could cause the browser to hang when a background page returned to the foreground. For example, the following code schedules a transition every second: - -```js -setInterval(function() { - d3.selectAll("div").transition().call(someAnimation); // BAD -}, 1000); -``` - -If such code runs in the background for hours, thousands of queued transitions will try to run simultaneously when the page is foregrounded. D3 4.0 avoids this hang by freezing time in the background: when a page is in the background, time does not advance, and so no queue of timers accumulates to run when the page returns to the foreground. Use d3.timer instead of transitions to schedule a long-running animation, or use [d3.timeout](https://github.com/d3/d3-timer/blob/master/README.md#timeout) and [d3.interval](https://github.com/d3/d3-timer/blob/master/README.md#interval) in place of setTimeout and setInterval to prevent transitions from being queued in the background: - -```js -d3.interval(function() { - d3.selectAll("div").transition().call(someAnimation); // GOOD -}, 1000); -``` - -By freezing time in the background, timers are effectively “unaware” of being backgrounded. It’s like nothing happened! 4.0 also now uses high-precision time ([performance.now](https://developer.mozilla.org/en-US/docs/Web/API/Performance/now)) where available; the current time is available as [d3.now](https://github.com/d3/d3-timer/blob/master/README.md#now). - -## [Transitions (d3-transition)](https://github.com/d3/d3-transition/blob/master/README.md) - -The [*selection*.transition](https://github.com/d3/d3-transition/blob/master/README.md#selection_transition) method now takes an optional *transition* instance which can be used to synchronize a new transition with an existing transition. (This change is discussed further in [What Makes Software Good?](https://medium.com/@mbostock/what-makes-software-good-943557f8a488)) For example: - -```js -var t = d3.transition() - .duration(750) - .ease(d3.easeLinear); - -d3.selectAll(".apple").transition(t) - .style("fill", "red"); - -d3.selectAll(".orange").transition(t) - .style("fill", "orange"); -``` - -Transitions created this way inherit timing from the closest ancestor element, and thus are synchronized even when the referenced *transition* has variable timing such as a staggered delay. This method replaces the deeply magical behavior of *transition*.each in 3.x; in 4.0, [*transition*.each](https://github.com/d3/d3-transition/blob/master/README.md#transition_each) is identical to [*selection*.each](https://github.com/d3/d3-selection/blob/master/README.md#selection_each). Use the new [*transition*.on](https://github.com/d3/d3-transition/blob/master/README.md#transition_on) method to listen to transition events. - -The meaning of [*transition*.delay](https://github.com/d3/d3-transition/blob/master/README.md#transition_delay) has changed for chained transitions created by [*transition*.transition](https://github.com/d3/d3-transition/blob/master/README.md#transition_transition). The specified delay is now relative to the *previous* transition in the chain, rather than the *first* transition in the chain; this makes it easier to insert interstitial pauses. For example: - -```js -d3.selectAll(".apple") - .transition() // First fade to green. - .style("fill", "green") - .transition() // Then red. - .style("fill", "red") - .transition() // Wait one second. Then brown, and remove. - .delay(1000) - .style("fill", "brown") - .remove(); -``` - -Time is now frozen in the background; see [d3-timer](#timers-d3-timer) for more information. While it was previously the case that transitions did not run in the background, now they pick up where they left off when the page returns to the foreground. This avoids page hangs by not scheduling an unbounded number of transitions in the background. If you want to schedule an infinitely-repeating transition, use transition events, or use [d3.timeout](https://github.com/d3/d3-timer/blob/master/README.md#timeout) and [d3.interval](https://github.com/d3/d3-timer/blob/master/README.md#interval) in place of [setTimeout](https://developer.mozilla.org/en-US/docs/Web/API/WindowTimers/setTimeout) and [setInterval](https://developer.mozilla.org/en-US/docs/Web/API/WindowTimers/setInterval). - -The [*selection*.interrupt](https://github.com/d3/d3-transition/blob/master/README.md#selection_interrupt) method now cancels all scheduled transitions on the selected elements, in addition to interrupting any active transition. When transitions are interrupted, any resources associated with the transition are now released immediately, rather than waiting until the transition starts, improving performance. (See also [*timer*.stop](https://github.com/d3/d3-timer/blob/master/README.md#timer_stop).) The new [d3.interrupt](https://github.com/d3/d3-transition/blob/master/README.md#interrupt) method is an alternative to [*selection*.interrupt](https://github.com/d3/d3-transition/blob/master/README.md#selection_interrupt) for quickly interrupting a single node. - -The new [d3.active](https://github.com/d3/d3-transition/blob/master/README.md#active) method allows you to select the currently-active transition on a given *node*, if any. This is useful for modifying in-progress transitions and for scheduling infinitely-repeating transitions. For example, this transition continuously oscillates between red and blue: - -```js -d3.select("circle") - .transition() - .on("start", function repeat() { - d3.active(this) - .style("fill", "red") - .transition() - .style("fill", "blue") - .transition() - .on("start", repeat); - }); -``` - -The [life cycle of a transition](https://github.com/d3/d3-transition/blob/master/README.md#the-life-of-a-transition) is now more formally defined and enforced. For example, attempting to change the duration of a running transition now throws an error rather than silently failing. The [*transition*.remove](https://github.com/d3/d3-transition/blob/master/README.md#transition_remove) method has been fixed if multiple transition names are in use: the element is only removed if it has no scheduled transitions, regardless of name. The [*transition*.ease](https://github.com/d3/d3-transition/blob/master/README.md#transition_ease) method now always takes an [easing function](#easings-d3-ease), not a string. When a transition ends, the tweens are invoked one last time with *t* equal to exactly 1, regardless of the associated easing function. - -As with [selections](#selections-d3-selection) in 4.0, all transition callback functions now receive the standard arguments: the element’s datum (*d*), the element’s index (*i*), and the element’s group (*nodes*), with *this* as the element. This notably affects [*transition*.attrTween](https://github.com/d3/d3-transition/blob/master/README.md#transition_attrTween) and [*transition*.styleTween](https://github.com/d3/d3-transition/blob/master/README.md#transition_styleTween), which no longer pass the *tween* function the current attribute or style value as the third argument. The *transition*.attrTween and *transition*.styleTween methods can now be called in getter modes for debugging or to share tween definitions between transitions. - -Homogenous transitions are now optimized! If all elements in a transition share the same tween, interpolator, or event listeners, this state is now shared across the transition rather than separately allocated for each element. 4.0 also uses an optimized default interpolator in place of [d3.interpolate](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolate) for [*transition*.attr](https://github.com/d3/d3-transition/blob/master/README.md#transition_attr) and [*transition*.style](https://github.com/d3/d3-transition/blob/master/README.md#transition_style). And transitions can now interpolate both [CSS](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateTransformCss) and [SVG](https://github.com/d3/d3-interpolate/blob/master/README.md#interpolateTransformSvg) transforms. - -For reusable components that support transitions, such as [axes](#axes-d3-axis), a new [*transition*.selection](https://github.com/d3/d3-transition/blob/master/README.md#transition_selection) method returns the [selection](#selections-d3-selection) that corresponds to a given transition. There is also a new [*transition*.merge](https://github.com/d3/d3-transition/blob/master/README.md#transition_merge) method that is equivalent to [*selection*.merge](https://github.com/d3/d3-selection/blob/master/README.md#selection_merge). - -For the sake of parsimony, the multi-value map methods have been extracted to [d3-selection-multi](https://github.com/d3/d3-selection-multi) and are no longer part of the default bundle. The multi-value map methods have also been renamed to plural form to reduce overload: [*transition*.attrs](https://github.com/d3/d3-selection-multi/blob/master/README.md#transition_attrs) and [*transition*.styles](https://github.com/d3/d3-selection-multi/blob/master/README.md#transition_styles). - -## [Voronoi Diagrams (d3-voronoi)](https://github.com/d3/d3-voronoi/blob/master/README.md) - -The d3.geom.voronoi method has been renamed to [d3.voronoi](https://github.com/d3/d3-voronoi/blob/master/README.md#voronoi), and the *voronoi*.clipExtent method has been renamed to [*voronoi*.extent](https://github.com/d3/d3-voronoi/blob/master/README.md#voronoi_extent). The undocumented *polygon*.point property in 3.x, which is the element in the input *data* corresponding to the polygon, has been renamed to *polygon*.data. - -Calling [*voronoi*](https://github.com/d3/d3-voronoi/blob/master/README.md#_voronoi) now returns the full [Voronoi diagram](https://github.com/d3/d3-voronoi/blob/master/README.md#voronoi-diagrams), which includes topological information: each Voronoi edge exposes *edge*.left and *edge*.right specifying the sites on either side of the edge, and each Voronoi cell is defined as an array of these edges and a corresponding site. The Voronoi diagram can be used to efficiently compute both the Voronoi and Delaunay tessellations for a set of points: [*diagram*.polygons](https://github.com/d3/d3-voronoi/blob/master/README.md#diagram_polygons), [*diagram*.links](https://github.com/d3/d3-voronoi/blob/master/README.md#diagram_links), and [*diagram*.triangles](https://github.com/d3/d3-voronoi/blob/master/README.md#diagram_triangles). The new topology is also useful in conjunction with TopoJSON; see the [Voronoi topology example](https://bl.ocks.org/mbostock/cd52a201d7694eb9d890). - -The [*voronoi*.polygons](https://github.com/d3/d3-voronoi/blob/master/README.md#voronoi_polygons) and [*diagram*.polygons](https://github.com/d3/d3-voronoi/blob/master/README.md#diagram_polygons) now require an [extent](https://github.com/d3/d3-voronoi/blob/master/README.md#voronoi_extent); there is no longer an implicit extent of ±1e6. The [*voronoi*.links](https://github.com/d3/d3-voronoi/blob/master/README.md#voronoi_links), [*voronoi*.triangles](https://github.com/d3/d3-voronoi/blob/master/README.md#voronoi_triangles), [*diagram*.links](https://github.com/d3/d3-voronoi/blob/master/README.md#diagram_links) and [*diagram*.triangles](https://github.com/d3/d3-voronoi/blob/master/README.md#diagram_triangles) are now affected by the clip extent: as the Delaunay is computed as the dual of the Voronoi, two sites are only linked if the clipped cells are touching. To compute the Delaunay triangulation without respect to clipping, set the extent to null. - -The Voronoi generator finally has well-defined behavior for coincident vertices: the first of a set of coincident points has a defined cell, while the subsequent duplicate points have null cells. The returned array of polygons is sparse, so by using *array*.forEach or *array*.map, you can easily skip undefined cells. The Voronoi generator also now correctly handles the case where no cell edges intersect the extent. - -## [Zooming (d3-zoom)](https://github.com/d3/d3-zoom/blob/master/README.md) - -The zoom behavior d3.behavior.zoom has been renamed to d3.zoom. Zoom behaviors no longer store the active zoom transform (*i.e.*, the visible region; the scale and translate) internally. The zoom transform is now stored on any elements to which the zoom behavior has been applied. The zoom transform is available as *event*.transform within a zoom event or by calling [d3.zoomTransform](https://github.com/d3/d3-zoom/blob/master/README.md#zoomTransform) on a given *element*. To zoom programmatically, use [*zoom*.transform](https://github.com/d3/d3-zoom/blob/master/README.md#zoom_transform) with a given [selection](#selections-d3-selection) or [transition](#transitions-d3-transition); see the [zoom transitions example](https://bl.ocks.org/mbostock/b783fbb2e673561d214e09c7fb5cedee). The *zoom*.event method has been removed. - -To make programmatic zooming easier, there are several new convenience methods on top of *zoom*.transform: [*zoom*.translateBy](https://github.com/d3/d3-zoom/blob/master/README.md#zoom_translateBy), [*zoom*.scaleBy](https://github.com/d3/d3-zoom/blob/master/README.md#zoom_scaleBy) and [*zoom*.scaleTo](https://github.com/d3/d3-zoom/blob/master/README.md#zoom_scaleTo). There is also a new API for describing [zoom transforms](https://github.com/d3/d3-zoom/blob/master/README.md#zoom-transforms). Zoom behaviors are no longer dependent on [scales](#scales-d3-scale), but you can use [*transform*.rescaleX](https://github.com/d3/d3-zoom/blob/master/README.md#transform_rescaleX), [*transform*.rescaleY](https://github.com/d3/d3-zoom/blob/master/README.md#transform_rescaleY), [*transform*.invertX](https://github.com/d3/d3-zoom/blob/master/README.md#transform_invertX) or [*transform*.invertY](https://github.com/d3/d3-zoom/blob/master/README.md#transform_invertY) to transform a scale’s domain. 3.x’s *event*.scale is replaced with *event*.transform.k, and *event*.translate is replaced with *event*.transform.x and *event*.transform.y. The *zoom*.center method has been removed in favor of programmatic zooming. - -The zoom behavior finally supports simple constraints on panning! The new [*zoom*.translateExtent](https://github.com/d3/d3-zoom/blob/master/README.md#zoom_translateExtent) lets you define the viewable extent of the world: the currently-visible extent (the extent of the viewport, as defined by [*zoom*.extent](https://github.com/d3/d3-zoom/blob/master/README.md#zoom_extent)) is always contained within the translate extent. The *zoom*.size method has been replaced by *zoom*.extent, and the default behavior is now smarter: it defaults to the extent of the zoom behavior’s owner element, rather than being hardcoded to 960×500. (This also improves the default path chosen during smooth zoom transitions!) - -The zoom behavior’s interaction has also improved. It now correctly handles concurrent wheeling and dragging, as well as concurrent touching and mousing. The zoom behavior now ignores wheel events at the limits of its scale extent, allowing you to scroll past a zoomable area. The *zoomstart* and *zoomend* events have been renamed *start* and *end*. By default, zoom behaviors now ignore right-clicks intended for the context menu; use [*zoom*.filter](https://github.com/d3/d3-zoom/blob/master/README.md#zoom_filter) to control which events are ignored. The zoom behavior also ignores emulated mouse events on iOS. The zoom behavior now consumes handled events, making it easier to combine with other interactive behaviors such as [dragging](#dragging-d3-drag). diff --git a/node_modules/d3/LICENSE b/node_modules/d3/LICENSE deleted file mode 100644 index 1d9d875edb469786a9c6dbae5aaeef9a3bcb2c33..0000000000000000000000000000000000000000 --- a/node_modules/d3/LICENSE +++ /dev/null @@ -1,27 +0,0 @@ -Copyright 2010-2017 Mike Bostock -All rights reserved. - -Redistribution and use in source and binary forms, with or without modification, -are permitted provided that the following conditions are met: - -* Redistributions of source code must retain the above copyright notice, this - list of conditions and the following disclaimer. - -* Redistributions in binary form must reproduce the above copyright notice, - this list of conditions and the following disclaimer in the documentation - and/or other materials provided with the distribution. - -* Neither the name of the author nor the names of contributors may be used to - endorse or promote products derived from this software without specific prior - written permission. - -THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" AND -ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED -WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE -DISCLAIMED.

It provides an interface just like readFile, readFileSync, writeFile and writeFileSync, but with implementations that work the way you expect on stdin and stdout. If you use these methods on files other than /dev/stdin or /dev/stdout, they simply delegate to the fs methods, so you can trust that they behave identically to the methods you’re used to. - -For example, now you can read stdin synchronously like so: - -```js -var contents = rw.readFileSync("/dev/stdin", "utf8"); -``` - -Or to write to stdout: - -```js -rw.writeFileSync("/dev/stdout", contents, "utf8"); -``` - -And rw automatically squashes EPIPE errors, so you can pipe the output of your program to `head` and you won’t get a spurious stack trace. - -To install, `npm install rw`. - -### Note - -If you want to read synchronously from stdin using [readFileSync](#readFileSync), you cannot also use process.stdin in the same program. Likewise, if you want to write synchronously to stdout or stderr using [writeFileSync](#writeFileSync), you cannot use process.stdout or process.stderr, respectively. (This includes using console.log and the like!) Failure to heed this warning may result in error: EAGAIN, resource temporarily unavailable. Unfortunately, it does not appear possible for this library to fix this issue automatically, so please use caution. - -Only the asynchronous methods [readFile](#readFile) and [writeFile](#writeFile) are supported on Windows. Node has no synchronous API for reading from process.[stdin](https://nodejs.org/api/process.html#process_process_stdin) or writing to process.[stdout](https://nodejs.org/api/process.html#process_process_stdout) or process.[stderr](https://nodejs.org/api/process.html#process_process_stderr), so you’re out of luck! - -## API Reference - -# rw.readFile(path[, options], callback) - -Reads the file at the specified *path* completely into memory, invoking the specified *callback* once the data is available and the file is closed. The *callback* is invoked with two arguments: the *error* that occurred during read (hopefully null), and the read data. If *options* is a string, it specifies the encoding to use, in which case the read data will be a string; otherwise *options* is an object, and may specify encoding and flag properties. This method is a drop-in replacement for [fs.readFile](https://nodejs.org/api/fs.html#fs_fs_readfile_file_options_callback) and fixes the behavior of special files such as /dev/stdin. - -# rw.readFileSync(path[, options]) - -Reads the file at the specified *path* completely into memory, synchronously, returning the data. If an error occurred during read, this function throws an error instead. If *options* is a string, it specifies the encoding to use, in which case the read data will be a string; otherwise *options* is an object, and may specify encoding and flag properties. This method is a drop-in replacement for [fs.readFileSync](https://nodejs.org/api/fs.html#fs_fs_readfilesync_file_options) and fixes the behavior of special files such as /dev/stdin. - -# rw.writeFile(path, data[, options], callback) - -Writes the specified *data* (completely in memory) to a file at the specified *path*, invoking the specified *callback* once the data is completely written and the file is closed. The *callback* is invoked with a single argument: the *error* that occurred during write (hopefully null). If *options* is a string, it specifies the encoding to use, in which case the *data* must be a string; otherwise *options* is an object, and may specify encoding, mode and flag properties. This method is a drop-in replacement for [fs.writeFile](https://nodejs.org/api/fs.html#fs_fs_writefile_file_data_options_callback) and fixes the behavior of special files such as /dev/stdout. - -# rw.writeFileSync(path, data[, options]) - -Writes the specified *data* (completely in memory) to a file at the specified *path*, synchronously, returning once the data is completely written and the file is closed. Throws an *error* if one occurs during write. If *options* is a string, it specifies the encoding to use, in which case the *data* must be a string; otherwise *options* is an object, and may specify encoding, mode and flag properties. This method is a drop-in replacement for [fs.writeFileSync](https://nodejs.org/api/fs.html#fs_fs_writefilesync_file_data_options) and fixes the behavior of special files such as /dev/stdout. - -# rw.dash.readFile(path[, options], callback) - -Equivalent to [rw.readFile](#readFile), except treats a *path* of `-` as `/dev/stdin`.

Before Node.js 8, this buffer contained - *arbitrary memory* for performance reasons, which could include anything ranging from - program source code to passwords and encryption keys. -- `new Buffer('abc')` creates a `Buffer` that contains the UTF-8-encoded version of - the string `'abc'`. A second argument could specify another encoding: For example, - `new Buffer(string, 'base64')` could be used to convert a Base64 string into the original - sequence of bytes that it represents. -- There are several other combinations of arguments. - -This meant that, in code like `var buffer = new Buffer(foo);`, *it is not possible to tell -what exactly the contents of the generated buffer are* without knowing the type of `foo`. - -Sometimes, the value of `foo` comes from an external source. For example, this function -could be exposed as a service on a web server, converting a UTF-8 string into its Base64 form: - -``` -function stringToBase64(req, res) { - // The request body should have the format of `{ string: 'foobar' }` - const rawBytes = new Buffer(req.body.string) - const encoded = rawBytes.toString('base64') - res.end({ encoded: encoded }) -} -``` - -Note that this code does *not* validate the type of `req.body.string`: - -- `req.body.string` is expected to be a string. If this is the case, all goes well. -- `req.body.string` is controlled by the client that sends the request. -- If `req.body.string` is the *number* `50`, the `rawBytes` would be 50 bytes: - - Before Node.js 8, the content would be uninitialized - - After Node.js 8, the content would be `50` bytes with the value `0` - -Because of the missing type check, an attacker could intentionally send a number -as part of the request. Using this, they can either: - -- Read uninitialized memory. This **will** leak passwords, encryption keys and other - kinds of sensitive information. (Information leak) -- Force the program to allocate a large amount of memory. For example, when specifying - `500000000` as the input value, each request will allocate 500MB of memory. - This can be used to either exhaust the memory available of a program completely - and make it crash, or slow it down significantly. (Denial of Service) - -Both of these scenarios are considered serious security issues in a real-world -web server context. - -when using `Buffer.from(req.body.string)` instead, passing a number will always -throw an exception instead, giving a controlled behaviour that can always be -handled by the program. - - -### The `Buffer()` constructor has been deprecated for a while. Is this really an issue? - -Surveys of code in the `npm` ecosystem have shown that the `Buffer()` constructor is still -widely used.

After some -discussion, it was decided to move my approach into a separate package, and _this is that separate -package_. - -This footgun is not imaginary — I observed top-downloaded packages doing that kind of thing, -«fixing» the lint warning by blindly including `safe-buffer` without any actual changes. - -Also in some cases, even if the API _was_ migrated to use of safe Buffer API — a random pull request -can bring unsafe Buffer API usage back to the codebase by adding new calls — and that could go -unnoticed even if you have a linter prohibiting that (becase of the reason stated above), and even -pass CI. _I also observed that being done in popular packages._ - -Some examples: - * [webdriverio](https://github.com/webdriverio/webdriverio/commit/05cbd3167c12e4930f09ef7cf93b127ba4effae4#diff-124380949022817b90b622871837d56cR31) - (a module with 548 759 downloads/month), - * [websocket-stream](https://github.com/maxogden/websocket-stream/commit/c9312bd24d08271687d76da0fe3c83493871cf61) - (218 288 d/m, fix in [maxogden/websocket-stream#142](https://github.com/maxogden/websocket-stream/pull/142)), - * [node-serialport](https://github.com/node-serialport/node-serialport/commit/e8d9d2b16c664224920ce1c895199b1ce2def48c) - (113 138 d/m, fix in [node-serialport/node-serialport#1510](https://github.com/node-serialport/node-serialport/pull/1510)), - * [karma](https://github.com/karma-runner/karma/commit/3d94b8cf18c695104ca195334dc75ff054c74eec) - (3 973 193 d/m, fix in [karma-runner/karma#2947](https://github.com/karma-runner/karma/pull/2947)), - * [spdy-transport](https://github.com/spdy-http2/spdy-transport/commit/5375ac33f4a62a4f65bcfc2827447d42a5dbe8b1) - (5 970 727 d/m, fix in [spdy-http2/spdy-transport#53](https://github.com/spdy-http2/spdy-transport/pull/53)). - * And there are a lot more over the ecosystem. - -I filed a PR at -[mysticatea/eslint-plugin-node#110](https://github.com/mysticatea/eslint-plugin-node/pull/110) to -partially fix that (for cases when that lint rule is used), but it is a semver-major change for -linter rules and presets, so it would take significant time for that to reach actual setups. -_It also hasn't been released yet (2018-03-20)._ - -Also, `safer-buffer` discourages the usage of `.allocUnsafe()`, which is often done by a mistake. -It still supports it with an explicit concern barier, by placing it under -`require('safer-buffer/dangereous')`. - -## But isn't throwing bad? - -Not really. It's an error that could be noticed and fixed early, instead of causing havoc later like -unguarded `new Buffer()` calls that end up receiving user input can do. - -This package affects only the files where `var Buffer = require('safer-buffer').Buffer` was done, so -it is really simple to keep track of things and make sure that you don't mix old API usage with that. -Also, CI should hint anything that you might have missed. - -New commits, if tested, won't land new usage of unsafe Buffer API this way. -_Node.js 10.x also deals with that by printing a runtime depecation warning._ - -### Would it affect third-party modules? - -No, unless you explicitly do an awful thing like monkey-patching or overriding the built-in `Buffer`. -Don't do that. - -### But I don't want throwing… - -That is also fine! - -Also, it could be better in some cases when you don't comprehensive enough test coverage. - -In that case — just don't override `Buffer` and use -`var SaferBuffer = require('safer-buffer').Buffer` instead. - -That way, everything using `Buffer` natively would still work, but there would be two drawbacks: - -* `Buffer.from`/`Buffer.alloc` won't be polyfilled — use `SaferBuffer.from` and - `SaferBuffer.alloc` instead. -* You are still open to accidentally using the insecure deprecated API — use a linter to catch that. - -Note that using a linter to catch accidential `Buffer` constructor usage in this case is strongly -recommended. `Buffer` is not overriden in this usecase, so linters won't get confused. - -## «Without footguns»? - -Well, it is still possible to do _some_ things with `Buffer` API, e.g. accessing `.buffer` property -on older versions and duping things from there. You shouldn't do that in your code, probabably. - -The intention is to remove the most significant footguns that affect lots of packages in the -ecosystem, and to do it in the proper way. - -Also, this package doesn't protect against security issues affecting some Node.js versions, so for -usage in your own production code, it is still recommended to update to a Node.js version -[supported by upstream](https://github.com/nodejs/release#release-schedule). diff --git a/node_modules/safer-buffer/dangerous.js b/node_modules/safer-buffer/dangerous.js deleted file mode 100644 index ca41fdc549b6553e811d35e44730a51bec68be99..0000000000000000000000000000000000000000 --- a/node_modules/safer-buffer/dangerous.js +++ /dev/null @@ -1,58 +0,0 @@ -/* eslint-disable node/no-deprecated-api */ - -'use strict' - -var buffer = require('buffer') -var Buffer = buffer.Buffer -var safer = require('./safer.js') -var Safer = safer.Buffer - -var dangerous = {} - -var key - -for (key in safer) { - if (!safer.hasOwnProperty(key)) continue - dangerous[key] = safer[key] -} - -var Dangereous = dangerous.Buffer = {} - -// Copy Safer API -for (key in Safer) { - if (!Safer.hasOwnProperty(key)) continue - Dangereous[key] = Safer[key] -} - -// Copy those missing unsafe methods, if they are present -for (key in Buffer) { - if (!Buffer.hasOwnProperty(key)) continue - if (Dangereous.hasOwnProperty(key)) continue - Dangereous[key] = Buffer[key] -} - -if (!Dangereous.allocUnsafe) { - Dangereous.allocUnsafe = function (size) { - if (typeof size !== 'number') { - throw new TypeError('The "size" argument must be of type number.
