axis.ticks(arguments…) axis.ticks([count[, specifier]]) axis.ticks([interval[, specifier]]) Sets the arguments that will be passed to scale.ticks and scale.tickFormat when the axis is rendered, and returns the axis generator. The meaning of the arguments depends on the axis’ scale type: most commonly, the arguments are a suggested count for the number of ticks (or a time interval for time scales), and an optional format specifier to customize how the tick values are formatted. For example, to

d3.treemapSlice(node, x0, y0, x1, y1) Divides the rectangular area specified by x0, y0, x1, y1 vertically according the value of each of the specified node’s children. The children are positioned in order, starting with the top edge (y0) of the given rectangle. If the sum of the children’s values is less than the specified node’s value (i.e., if the specified node has a non-zero internal value), the remaining empty space will be positioned on the bottom edge (y1) of the given rectangle.

pie.sort([compare]) If compare is specified, sets the data comparator to the specified function and returns this pie generator. If compare is not specified, returns the current data comparator, which defaults to null. If both the data comparator and the value comparator are null, then arcs are positioned in the original input order. Otherwise, the data is sorted according to the data comparator, and the resulting order is used. Setting the data comparator implicitly sets the value comparator

d3.geoOrthographic() d3.geoOrthographicRaw The orthographic projection; see d3-geo.

d3.geoGringortenQuincuncial() The Gringorten square equal-area projection.

axis.tickPadding([padding]) If padding is specified, sets the padding to the specified value in pixels and returns the axis. If padding is not specified, returns the current padding which defaults to 3 pixels.

set.remove(value) If the set contains the specified value string, removes it and returns true. Otherwise, this method does nothing and returns false.

stream.point(x, y[, z]) Indicates a point with the specified coordinates x and y (and optionally z). The coordinate system is unspecified and implementation-dependent; for example, projection streams require spherical coordinates in degrees as input. Outside the context of a polygon or line, a point indicates a point geometry object (Point or MultiPoint). Within a line or polygon ring, the point indicates a control point.

transition.duration([value]) For each selected element, sets the transition duration to the specified value in milliseconds. The value may be specified either as a constant or a function. If a function, it is immediately evaluated for each selected element, in order, being passed the current datum d and index i, with the this context as the current DOM element. The function’s return value is then used to set each element’s transition duration. If a duration is not specified, it defaults to 2

d3.keys(object) Returns an array containing the property names of the specified object (an associative array). The order of the returned array is undefined.
