d3.interpolatePuRd(t) d3.schemePuRd Given a number t in the range [0,1], returns the corresponding color from the “PuRd” sequential color scheme represented as an RGB string.

circle(arguments…) Returns a new GeoJSON geometry object of type “Polygon” approximating a circle on the surface of a sphere, with the current center, radius and precision. Any arguments are passed to the accessors.

d3.geoTransverseMercator() d3.geoTransverseMercatorRaw The transverse spherical Mercator projection; see d3-geo.

d3.geoGraticule10() A convenience method for directly generating the default 10° global graticule as a GeoJSON MultiLineString geometry object. Equivalent to: function geoGraticule10() { return d3.geoGraticule()(); }

collide.strength([strength]) If strength is specified, sets the force strength to the specified number in the range [0,1] and returns this force. If strength is not specified, returns the current strength which defaults to 0.7. Overlapping nodes are resolved through iterative relaxation. For each node, the other nodes that are anticipated to overlap at the next tick (using the anticipated positions ⟨x + vx,y + vy⟩) are determined; the node’s velocity is then modified to push the node out of

log(value) See continuous.

quantize.range([range]) If range is specified, sets the scale’s range to the specified array of values. The array may contain any number of discrete values. The elements in the given array need not be numbers; any value or type will work. If range is not specified, returns the scale’s current range.

d3.schemePastel2 An array of eight categorical colors represented as RGB hexadecimal strings.

gingery.radius([radius]) Defaults to 30°.

satellite.distance([distance]) Distance from the center of the sphere to the point of view, as a proportion of the sphere’s radius; defaults to 2.0. The recommended maximum clip angle for a given distance is acos(1 / distance) converted to degrees. If tilt is also applied, then more conservative clipping may be necessary. For exact clipping, the in-development geographic projection pipeline is needed; see the satellite example.
