band(value) Given a value in the input domain, returns the start of the corresponding band derived from the output range. If the given value is not in the scale’s domain, returns undefined.

d3.randomBates(n) Returns a function for generating random numbers with a Bates distribution with n independent variables.

d3.scaleQuantize() Constructs a new quantize scale with the unit domain [0, 1] and the unit range [0, 1]. Thus, the default quantize scale is equivalent to the Math.round function.

path.lineTo(x, y) Draws a straight line from the current point to the specified point ⟨x, y⟩. Equivalent to context.lineTo and SVG’s “lineto” command.

curve.lineStart() Indicates the start of a new line segment. Zero or more points will follow.

radialLine.context([context]) Equivalent to line.context.

d3.geoGilbert([type]) Gilbert’s two-world perspective projection. Wraps an instance of the specified projection type; if not specified, defaults to d3.geoOrthographic.

d3.timeSundays(start, stop[, step]) d3.utcSundays(start, stop[, step]) Aliases for timeSunday.range and utcSunday.range.

d3.pairs(array) For each adjacent pair of elements in the specified array, returns a new array of tuples of element i and element i - 1. For example: d3.pairs([1, 2, 3, 4]); // returns [[1, 2], [2, 3], [3, 4]] If the specified array has fewer than two elements, returns the empty array.

d3.symbolDiamond The rhombus symbol type.
