transition.size() Returns the total number of elements in this transition. Equivalent to selection.size.

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

quadtree.addAll(data) Adds the specified array of data to the quadtree, deriving each element’s coordinates ⟨x,y⟩ using the current x- and y-accessors, and return this quadtree. This is approximately equivalent to calling quadtree.add repeatedly: for (var i = 0, n = data.length; i < n; ++i) { quadtree.add(data[i]); } However, this method results in a more compact quadtree because the extent of the data is computed first before adding the data.

berghaus.lobes([lobes]) If lobes is specified, sets the number of lobes in the resulting star, and returns this projection. If lobes is not specified, returns the current lobe number, which defaults to 5.

d3.randomExponential(lambda) Returns a function for generating random numbers with an exponential distribution with the rate lambda; equivalent to time between events in a Poisson process with a mean of 1 / lambda. For example, exponential(1/40) generates random times between events where, on average, one event occurs every 40 units of time.

d3.geoCylindricalStereographic() d3.geoCylindricalStereographicRaw(phi0) The cylindrical stereographic projection. Depending on the chosen parallel, this projection is also known as Braun’s stereographic (0°) and Gall’s stereographic (45°).

d3.easeBackIn(t) Anticipatory easing, like a dancer bending his knees before jumping off the floor. The degree of overshoot is configurable; it not specified, it defaults to 1.70158.

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

d3.scaleLinear() Constructs a new continuous scale with the unit domain [0, 1], the unit range [0, 1], the default interpolator and clamping disabled. Linear scales are a good default choice for continuous quantitative data because they preserve proportional differences. Each range value y can be expressed as a function of the domain value x: y = mx + b.

voronoi.extent([extent]) If extent is specified, sets the clip extent of the Voronoi layout to the specified bounds and returns the layout. The extent bounds are specified as an array [[x0, y0], [x1, y1]], where x0 is the left side of the extent, y0 is the top, x1 is the right and y1 is the bottom. If extent is not specified, returns the current clip extent which defaults to null. A clip extent is required when using voronoi.polygons.
