d3.geoCraster() d3.geoCrasterRaw The Craster parabolic projection; also known as Putniņš P4.

d3.mean(array[, accessor]) Returns the mean of the given array of numbers. If the array is empty, returns undefined. An optional accessor function may be specified, which is equivalent to calling array.map(accessor) before computing the mean. This method ignores undefined and NaN values; this is useful for ignoring missing data.

d3.json(url[, callback]) Creates a request for the JSON file at the specified url with the default mime type application/json. This convenience constructor is approximately equivalent to: d3.request(url) .mimeType("application/json") .response(function(xhr) { return JSON.parse(xhr.responseText); }) .get(callback);

radialLine.defined([defined]) Equivalent to line.defined.

diagram.triangles() Returns the Delaunay triangulation of the specified data array as an array of triangles. Each triangle is a three-element array of elements from data. Since the triangulation is computed as the dual of the Voronoi diagram, and the Voronoi diagram is clipped by the extent, a subset of the Delaunay triangulation is returned.

d3.timeSeconds(start, stop[, step]) d3.utcSeconds(start, stop[, step]) Aliases for timeSecond.range and utcSecond.range.
