d3.geoGnomonic() d3.geoGnomonicRaw The gnomonic projection.

d3.geoModifiedStereographicGs50() A modified stereographic projection for the United States including Alaska and Hawaii. Typically clipped to the geographic extent [[-180°, 15°], [-50°, 75°]].

d3.descending(a, b) Returns -1 if a is greater than b, or 1 if a is less than b, or 0. This is the comparator function for reverse natural order, and can be used in conjunction with the built-in array sort method to arrange elements in descending order. It is implemented as: function descending(a, b) { return b < a ? -1 : b > a ? 1 : b >= a ? 0 : NaN; } Note that if no comparator function is specified to the built-in sort method, the default order is lexicographic (alphabetical), n

point.domain([domain]) If domain is specified, sets the domain to the specified array of values. The first element in domain will be mapped to the first point, the second domain value to the second point, and so on. Domain values are stored internally in a map from stringified value to index; the resulting index is then used to determine the point. Thus, a point scale’s values must be coercible to a string, and the stringified version of the domain value uniquely identifies the corresponding p

map.values() Returns an array of values for every entry in this map. The order of the returned values is arbitrary.

curve.areaStart() Indicates the start of a new area segment. Each area segment consists of exactly two line segments: the topline, followed by the baseline, with the baseline points in reverse order.

d3.tree() Creates a new tree layout with default settings.

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

d3.easeCubic(t) d3.easeCubicInOut(t) Symmetric cubic easing; scales cubicIn for t in [0, 0.5] and cubicOut for t in [0.5, 1]. Also equivalent to poly.exponent(3).

d3.forceCenter([x, y]) Creates a new centering force with the specified x- and y- coordinates. If x and y are not specified, they default to ⟨0,0⟩.
