d3.geoMiller() d3.geoMillerRaw The Miller cylindrical projection is a modified Mercator projection.

treemap.paddingInner([padding]) If padding is specified, sets the inner padding to the specified number or function and returns this treemap layout. If padding is not specified, returns the current inner padding function, which defaults to the constant zero. If padding is a function, it is invoked for each node with children, being passed the current node. The inner padding is used to separate a node’s adjacent children.

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

d3.precisionPrefix(step, value) Returns a suggested decimal precision for use with locale.formatPrefix given the specified numeric step and reference value. The step represents the minimum absolute difference between values that will be formatted, and value determines which SI prefix will be used. (This assumes that the values to be formatted are also multiples of step.) For example, given the numbers 1.1e6, 1.2e6, and 1.3e6, the step should be 1e5, the value could be 1.3e6, and the suggested

pow.invert(value) See continuous.invert.

d3.path() Constructs a new path serializer that implements CanvasPathMethods.

d3.geoGinzburg4() d3.geoGinzburg4Raw The Ginzburg IV projection.

path.rect(x, y, w, h) Creates a new subpath containing just the four points ⟨x, y⟩, ⟨x + w, y⟩, ⟨x + w, y + h⟩, ⟨x, y + h⟩, with those four points connected by straight lines, and then marks the subpath as closed. Equivalent to context.rect and uses SVG’s “lineto” commands.

pow.clamp(clamp) See continuous.clamp.

d3.geoBromley() d3.geoBromleyRaw The Bromley projection is a rescaled Mollweide projection.
