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.

stratify.parentId([parentId]) If parentId is specified, sets the parent id accessor to the given function and returns this stratify operator. Otherwise, returns the current parent id accessor, which defaults to: function parentId(d) { return d.parentId; } The parent id accessor is invoked for each element in the input data passed to the stratify operator, being passed the current datum (d) and the current index (i). The returned string is then used to identify the node’s relationships in c

map.has(key) Returns true if and only if this map has an entry for the specified key string. Note: the value may be null or undefined.

d3.text(url[, callback]) Creates a request for the text file at the specified url with the default mime type text/plain. This convenience constructor is approximately equivalent to: d3.request(url) .mimeType("text/plain") .response(function(xhr) { return xhr.responseText; }) .get(callback);

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

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")

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

d3.geoEquirectangular() d3.geoEquirectangularRaw The equirectangular (plate carrée) projection; see d3-geo. The Cassini projection is the transverse aspect of the equirectangular projection.

quantize.nice() Equivalent to continuous.nice.

d3.easeBounce(t) d3.easeBounceOut(t) Reverse bounce easing; equivalent to 1 - bounceIn(1 - t).
