d3.pie() Constructs a new pie generator with the default settings.

d3.thresholdFreedmanDiaconis(values, min, max) Returns the number of bins according to the Freedman–Diaconis rule; the input values must be numbers.

rectangularPolyconic.parallel([parallel]) Defaults to 0°.

d3.timeSecond d3.utcSecond Seconds (e.g., 01:23:45.0000 AM); 1,000 milliseconds.

d3.curveCatmullRomClosed(context) Produces a closed cubic Catmull–Rom spline using the specified control points and the parameter alpha, which defaults to 0.5, as proposed by Yuksel et al. When a line segment ends, the first three control points are repeated, producing a closed loop.

tsv2json [options…] [file] Equivalent to dsv2json, but the input delimiter defaults to the tab character (\t).

d3.zoomTransform(node) Returns the current transform for the specified node. Note that node should typically be a DOM element, not a selection. (A selection may consist of multiple nodes, in different states, and this function only returns a single transform.) If you have a selection, call selection.node first: var transform = d3.zoomTransform(selection.node()); In the context of an event listener, the node is typically the element that received the input event (which should be equal to event

d3.curveStep(context) Produces a piecewise constant function (a step function) consisting of alternating horizontal and vertical lines. The y-value changes at the midpoint of each pair of adjacent x-values.

pow.rangeRound([range]) See continuous.rangeRound.

radialArea.curve([curve]) Equivalent to area.curve. Note that curveMonotoneX or curveMonotoneY are not recommended for radial areas because they assume that the data is monotonic in x or y, which is typically untrue of radial areas.
