d3.html(url[, callback]) Creates a request for the HTML file at the specified url with the default mime type text/html. The HTML file is returned as a document fragment. This convenience constructor is approximately equivalent to: d3.request(url) .mimeType("text/html") .response(function(xhr) { return document.createRange().createContextualFragment(xhr.responseText); }) .get(callback); HTML parsing requires a global document and relies on DOM Ranges, which are not supported by JSD

pow.invert(value) See continuous.invert.

set.size() Returns the number of values in this set.

d3.symbolTriangle The up-pointing triangle symbol type.

d3.interpolateTransformCss(a, b) Returns an interpolator between the two 2D CSS transforms represented by a and b. Each transform is decomposed to a standard representation of translate, rotate, x-skew and scale; these component transformations are then interpolated. This behavior is standardized by CSS: see matrix decomposition for animation.
