hammer.coefficient([coefficient]) Defaults to 2.

d3.curveStepBefore(context) Produces a piecewise constant function (a step function) consisting of alternating horizontal and vertical lines. The y-value changes before the x-value.

d3.geoEquirectangular() d3.geoEquirectangularRaw The equirectangular (plate carrée) projection.

d3.geoSatellite() d3.geoSatelliteRaw(P, omega) The satellite (tilted perspective) projection.

map.set(key, value) Sets the value for the specified key string. If the map previously had an entry for the same key string, the old entry is replaced with the new value. Returns the map, allowing chaining. For example: var map = d3.map() .set("foo", 1) .set("bar", 2) .set("baz", 3); map.get("foo"); // 1

pow.exponent([exponent]) If exponent is specified, sets the current exponent to the given numeric value. If exponent is not specified, returns the current exponent, which defaults to 1. (Note that this is effectively a linear scale until you set a different exponent.)

pack.size([size]) If size is specified, sets this pack layout’s size to the specified two-element array of numbers [width, height] and returns this pack layout. If size is not specified, returns the current size, which defaults to [1, 1].

d3.curveCatmullRom(context) Produces a cubic Catmull–Rom spline using the specified control points and the parameter alpha, which defaults to 0.5, as proposed by Yuksel et al. in On the Parameterization of Catmull–Rom Curves, with one-sided differences used for the first and last piece.

color.darker([k]) Returns a darker copy of this color. If k is specified, it controls how much darker the returned color should be. If k is not specified, it defaults to 1. The behavior of this method is dependent on the implementing color space.

path.toString() Returns the string representation of this path according to SVG’s path data specficiation.
