d3.geoBoggs() d3.geoBoggsRaw The Boggs eumorphic projection. More commonly used in interrupted form.

d3.interpolatePuBu(t) d3.schemePuBu Given a number t in the range [0,1], returns the corresponding color from the “PuBu” sequential color scheme represented as an RGB string.

d3.scaleImplicit A special value for ordinal.unknown that enables implicit domain construction: unknown values are implicitly added to the domain.

d3.schemeSet1 An array of nine categorical colors represented as RGB hexadecimal strings.

selection.lower() Re-inserts each selected element, in order, as the first child of its parent. Equivalent to: selection.each(function() { this.parentNode.insertBefore(this, this.parentNode.firstChild); });

set.values() 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: d3.set(["foo", "bar", "foo", "baz"]).values(); // "foo", "bar", "baz"

cluster.size([size]) If size is specified, sets this cluster layout’s size to the specified two-element array of numbers [width, height] and returns this cluster layout. If size is not specified, returns the current layout size, which defaults to [1, 1]. A layout size of null indicates that a node size will be used instead. The coordinates x and y represent an arbitrary coordinate system; for example, to produce a radial layout, a size of [360, radius] corresponds to a breadth of 360° and a

d3.curveCardinal(context) Produces a cubic cardinal spline using the specified control points, with one-sided differences used for the first and last piece. The default tension is 0.

d3.interpolateCool(t) Given a number t in the range [0,1], returns the corresponding color from Niccoli’s perceptual rainbow, represented as an RGB string.

d3.interpolateViridis(t) Given a number t in the range [0,1], returns the corresponding color from the “viridis” perceptually-uniform color scheme designed by van der Walt, Smith and Firing for matplotlib, represented as an RGB string.
