d3.geoWinkel3() d3.geoWinkel3Raw The Winkel tripel projection.

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

tree(root) Lays out the specified root hierarchy, assigning the following properties on root and its descendants: node.x - the x-coordinate of the node node.y - the y-coordinate of the node The coordinates x and y represent an arbitrary coordinate system; for example, you can treat x as an angle and y as a radius to produce a radial layout. You may want to call root.sort before passing the hierarchy to the tree layout.

d3.easeCubicIn(t) Cubic easing; equivalent to polyIn.exponent(3).

interval.floor(date) Returns a new date representing the latest interval boundary date before or equal to date. For example, timeDay.floor(date) typically returns 12:00 AM local time on the given date. This method is idempotent: if the specified date is already floored to the current interval, a new date with an identical time is returned. Furthermore, the returned date is the minimum expressible value of the associated interval, such that interval.floor(interval.floor(date) - 1) returns the

d3.geoAlbers() Alber’s equal-area conic projection; see d3-geo.

d3.cubehelix(h, s, l[, opacity]) d3.cubehelix(specifier) d3.cubehelix(color) Constructs a new Cubehelix color. The channel values are exposed as h, s and l properties on the returned instance. Use the Cubehelix color picker to explore this color space. If h, s and l are specified, these represent the channel values of the returned color; an opacity may also be specified. If a CSS Color Module Level 3 specifier string is specified, it is parsed and then converted to the Cubehelix color space.

d3.geoArmadillo() d3.geoArmadilloRaw(phi0) The armadillo projection. The default center assumes the default parallel of 20° and should be changed if a different parallel is used. Note: requires clipping to the sphere.

area.defined([defined]) If defined is specified, sets the defined accessor to the specified function or boolean and returns this area generator. If defined is not specified, returns the current defined accessor, which defaults to: function defined() { return true; } The default accessor thus assumes that the input data is always defined. When an area is generated, the defined accessor will be invoked for each element in the input data array, being passed the element d, the index i, and the

d3.geoLaskowski() d3.geoLaskowskiRaw The Laskowski tri-optimal projection simultaneously minimizes distance, angular, and areal distortion.
