d3.schemePaired An array of twelve categorical colors represented as RGB hexadecimal strings.

dispatch.apply(type[, that[, arguments]]) Like function.apply, invokes each registered callback for the specified type, passing the callback the specified arguments, with that as the this context. For example, if you wanted to dispatch your custom callbacks after handling a native click event, while preserving the current this context and arguments, you could say: selection.on("click", function() { dispatch.apply("custom", this, arguments); }); You can pass whatever arguments you want to c

y.strength([strength]) 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 y-velocity: (y - node.y) × strength. For example, a value of 0.1 indicates that the node should move a tenth of the way from its current y-position to the target y-position with each application. Higher values moves nodes more quickly to the target pos

d3.isoParse The full ISO 8601 UTC time parser. Where available, this method will use the Date constructor to parse strings. If you depend on strict validation of the input format according to ISO 8601, you should construct a UTC parser function: var strictIsoParse = d3.utcParse("%Y-%m-%dT%H:%M:%S.%LZ");

projection.rotate([angles]) If rotation is specified, sets the projection’s three-axis rotation 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. (These correspond to yaw, pitch and roll.) If the rotation angle gamma is omitted, it defaults to 0. See also d3.geoRotation. If rotation is not specified, returns the current rotation which defaults [0, 0, 0].

d3.scaleQuantile() Constructs a new quantile scale with an empty domain and an empty range. The quantile scale is invalid until both a domain and range are specified.

continuous.invert(value) Given a value from the range, returns the corresponding value from the 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: 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 is not enabled, the mapping may be extrapolated such that the returne

timer.stop() Stops this timer, preventing subsequent callbacks. This method has no effect if the timer has already stopped.

d3.geoAlbersUsa() This is a U.S.-centric composite projection of three d3.geoConicEqualArea projections: d3.geoAlbers is used for the lower forty-eight states, and separate conic equal-area projections are used for Alaska and Hawaii. Note that the scale for Alaska is diminished: it is projected at 0.35× its true relative area. This diagram by Philippe Rivière illustrates how this projection uses two rectangular insets for Alaska and Hawaii: See d3-composite-projections for more examples.

healpix.lobes([lobes]) If lobes is specified, sets the number of lobes (the parameter H in the literature) and returns this projection. If lobes is not specified, returns the current lobe number, which defaults to 4.
