selection.styles(values[, priority]) A convenience method on top of selection.style for setting multiple style properties. If the specified values is an object, the values may be specified either as strings or functions. For example: selection.styles({fill: "red", stroke: function(d) { return d.stroke; }}); If a value is a constant, all elements are given the same style property value; otherwise, if a value is a function, the function is evaluated for each selected element, in order, being pas

dispatch.call(type[, that[, arguments…]]) Like function.call, invokes each registered callback for the specified type, passing the callback the specified arguments, with that as the this context. See dispatch.apply for more information.

d3.timeYear d3.utcYear Years (e.g., January 1, 2012 at 12:00 AM); ranges from 365 to 366 days.

node.leaves() Returns the array of leaf nodes in traversal order; leaves are nodes with no children.

d3.easeElasticInOut(t) Symmetric elastic easing; scales elasticIn for t in [0, 0.5] and elasticOut for t in [0.5, 1].

d3.easeCubic(t) d3.easeCubicInOut(t) Symmetric cubic easing; scales cubicIn for t in [0, 0.5] and cubicOut for t in [0.5, 1]. Also equivalent to poly.exponent(3).

d3.forceCenter([x, y]) Creates a new centering force with the specified x- and y- coordinates. If x and y are not specified, they default to ⟨0,0⟩.

time.rangeRound([range]) See continuous.rangeRound.

area.lineX1() Returns a new line generator that has this area generator’s current defined accessor, curve and context. The line’s x-accessor is this area’s x1-accessor, and the line’s y-accessor is this area’s y0-accessor.

tree.nodeSize([size]) If size is specified, sets this tree layout’s node size to the specified two-element array of numbers [width, height] and returns this tree layout. If size is not specified, returns the current node size, which defaults to null. A node size of null indicates that a layout size will be used instead. When a node size is specified, the root node is always positioned at ⟨0, 0⟩.
