d3.interpolateSpectral(t) d3.schemeSpectral Given a number t in the range [0,1], returns the corresponding color from the “Spectral” diverging color scheme represented as an RGB string.

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); });

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.

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.timeSunday d3.utcSunday Sunday-based weeks (e.g., February 5, 2012 at 12:00 AM).

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