d3.symbolWye The Y-shape symbol type.

map.empty() Returns true if and only if this map has zero entries.

d3.interpolateBasisClosed(values) Returns a uniform nonrational B-spline interpolator through the specified array of values, which must be numbers. The control points are implicitly repeated such that the resulting one-dimensional spline has cyclical C² continuity when repeated around t in [0,1]. See also d3.curveBasisClosed.

d3.geoGinzburg5() d3.geoGinzburg5Raw The Ginzburg V projection.

point.step() Returns the distance between the starts of adjacent points.

d3.chord() Constructs a new chord layout with the default settings.

map.get(key) Returns the value for the specified key string. If the map does not have an entry for the specified key, returns undefined.

d3.active(node[, name]) 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: d3.selectAll("circle").transition() .delay(function(d, i) { return i * 50; }) .on("start", function repeat() { d3.active(this) .style("fill", "red")

d3.timeTuesdays(start, stop[, step]) d3.utcTuesdays(start, stop[, step]) Aliases for timeTuesday.range and utcTuesday.range.

point.bandwidth() Returns zero.
