cylindricalEqualArea.parallel([parallel]) Defaults to approximately 38.58°, fitting the world in a 960×500 rectangle.

d3.interpolateHcl(a, b) Returns an HCL color space interpolator between the two colors a and b. The colors a and b need not be in HCL; they will be converted to HCL using d3.hcl. If either color’s hue or chroma is NaN, the opposing color’s channel value is used. The shortest path between hues is used. The return value of the interpolator is an RGB string.

radialArea(data) Equivalent to area.

d3.geoMtFlatPolarSinusoidal() d3.geoMtFlatPolarSinusoidalRaw The McBryde–Thomas flat-polar sinusoidal equal-area projection.

d3.timerFlush() Immediately invoke any eligible timer callbacks. Note that zero-delay timers are normally first executed after one frame (~17ms). This can cause a brief flicker because the browser renders the page twice: once at the end of the first event loop, then again immediately on the first timer callback. By flushing the timer queue at the end of the first event loop, you can run any zero-delay timers immediately and avoid the flicker.

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.

radialArea.outerRadius([radius]) Equivalent to area.y1, except the accessor returns the radius: the distance from the origin ⟨0,0⟩.

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.
