d3.scaleIdentity() Constructs a new identity scale with the unit domain [0, 1] and the unit range [0, 1].

d3.stackOffsetWiggle(series, order) Shifts the baseline so as to minimize the weighted wiggle of layers. This offset is recommended for streamgraphs in conjunction with the inside-out order. See Stacked Graphs—Geometry & Aesthetics by Bryon & Wattenberg for more information.

voronoi.size([size]) An alias for voronoi.extent where the minimum x and y of the extent are ⟨0,0⟩. Equivalent to: voronoi.extent([[0, 0], size]);

D3 API Reference D3 4.0 is a collection of modules that are designed to work together; you can use the modules independently, or you can use them together as part of the default build. The source and documentation for each module is available in its repository. Follow the links below to learn more. For changes between 3.x and 4.0, see CHANGES; see also the 3.x reference. Arrays (Statistics, Search, Transformations, Histograms) Axes Brushes Chords Collections (Objects, Maps, Sets, Nests) Color

locale.utcFormat(specifier) Equivalent to locale.format, except all directives are interpreted as Coordinated Universal Time (UTC) rather than local time.

d3.schemeCategory10 An array of ten categorical colors represented as RGB hexadecimal strings.

d3.timeout(callback[, delay[, time]]) Like timer, except the timer automatically stops on its first callback. A suitable replacement for setTimeout that is guaranteed to not run in the background. The callback is passed the elapsed time.

log.rangeRound([range]) See continuous.rangeRound.

geo2svg [options…] [file] Converts the specified GeoJSON file to SVG. With --newline-delimited, each input feature is rendered as a separate path element; otherwise, a single path element is generated. By default, the SVG’s fill is set to none and the stroke is set to black. To override these values on a per-feature basis, the following GeoJSON feature properties will be propagated to attributes: fill fill-rule (or fillRule) fill-opacity (or fillOpacity) stroke stroke-width (or strokeWidth)

loximuthal.parallel([parallel]) Defaults to 40°.
