d3.polygonArea(polygon) <> Returns the signed area of the specified polygon. If the vertices of the polygon are in counterclockwise order (assuming a coordinate system where the origin ⟨0,0⟩ is in the top-left corner), the returned area is positive; otherwise it is negative, or zero.

interval.offset(date[, step]) Returns a new date equal to date plus step intervals. If step is not specified it defaults to 1. If step is negative, then the returned date will be before the specified date; if step is zero, then a copy of the specified date is returned; if step is not an integer, it is floored. This method does not round the specified date to the interval. For example, if date is today at 5:34 PM, then timeDay.offset(date, 1) returns 5:34 PM tomorrow (even if daylight saving

d3.timeWeeks(start, stop[, step]) d3.utcWeeks(start, stop[, step]) Aliases for timeWeek.range and utcWeek.range.

request.post([data][, callback]) Equivalent to request.send with the POST method: request.send("POST", data, callback);

airy.radius([radius]) Defaults to 90°.

path.moveTo(x, y) Move to the specified point ⟨x, y⟩. Equivalent to context.moveTo and SVG’s “moveto” command.

nest.rollup(function) Specifies a rollup function to be applied on each group of leaf elements. The return value of the rollup function will replace the array of leaf values in either the associative array returned by nest.map or nest.object; for nest.entries, it replaces the leaf entry.values with entry.value.

d3.csvFormat(rows[, columns]) Equivalent to dsvFormat(",").format.

d3.geoGingery() d3.geoGingeryRaw(rho, lobes) The U.S.-centric Gingery world projection, as inspired by Cram’s Air Age. Note: requires clipping to the sphere.

d3.easePolyOut(t) Reverse polynomial easing; equivalent to 1 - polyIn(1 - t). If the exponent is not specified, it defaults to 3, equivalent to cubicOut.
