interval.round(date) Returns a new date representing the closest interval boundary date to date. For example, timeDay.round(date) typically returns 12:00 AM local time on the given date if it is on or before noon, and 12:00 AM of the following day if it is after noon. This method is idempotent: if the specified date is already rounded to the current interval, a new date with an identical time is returned.

d3.timeWednesday d3.utcWednesday Wednesday-based weeks (e.g., February 8, 2012 at 12:00 AM).

d3.geoSinusoidal() d3.geoSinusoidalRaw The sinusoidal projection.

ribbon.endAngle([angle]) If angle is specified, sets the end angle accessor to the specified function and returns this ribbon generator. If angle is not specified, returns the current end angle accessor, which defaults to: function endAngle(d) { return d.endAngle; } The angle is specified in radians, with 0 at -y (12 o’clock) and positive angles proceeding clockwise.

d3.treemapSliceDice(node, x0, y0, x1, y1) If the specified node has odd depth, delegates to treemapSlice; otherwise delegates to treemapDice.

d3.namespace(name) Qualifies the specified name, which may or may not have a namespace prefix. If the name contains a colon (:), the substring before the colon is interpreted as the namespace prefix, which must be registered in d3.namespaces. Returns an object space and local attributes describing the full namespace URL and the local name. For example: d3.namespace("svg:text"); // {space: "http://www.w3.org/2000/svg", local: "text"} If the name does not contain a colon, this function merely r

d3.geoConicEqualArea() d3.geoConicEqualAreaRaw(phi0, phi1) The Albers’ equal-area conic projection. See also conic.parallels.

radialLine.angle([angle]) Equivalent to line.x, except the accessor returns the angle in radians, with 0 at -y (12 o’clock).

d3.curveBasisOpen(context) Produces a cubic basis spline using the specified control points. Unlike basis, the first and last points are not repeated, and thus the curve typically does not intersect these points.

d3.tsvFormatRows(rows) Equivalent to dsvFormat("\t").formatRows.
