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.

band.paddingOuter([padding]) If padding is specified, sets the outer padding to the specified value which must be in the range [0, 1]. If padding is not specified, returns the current outer padding which defaults to 0. The outer padding determines the ratio of the range that is reserved for blank space before the first band and after the last band.

manyBody.distanceMax([distance]) If distance is specified, sets the maximum distance between nodes over which this force is considered. If distance is not specified, returns the current maximum distance, which defaults to infinity. Specifying a finite maximum distance improves performance and produces a more localized layout.

axis.tickSizeInner([size]) If size is specified, sets the inner tick size to the specified value and returns the axis. If size is not specified, returns the current inner tick size, which defaults to 6. The inner tick size controls the length of the tick lines, offset from the native position of the axis.

band.domain([domain]) If domain is specified, sets the domain to the specified array of values. The first element in domain will be mapped to the first band, the second domain value to the second band, and so on. Domain values are stored internally in a map from stringified value to index; the resulting index is then used to determine the band. Thus, a band scale’s values must be coercible to a string, and the stringified version of the domain value uniquely identifies the corresponding band

d3.geoPolyhedralWaterman() Steve Waterman’s butterfly projection.

loximuthal.parallel([parallel]) Defaults to 40°.

geo2svg [options…] [file] Converts the specified GeoJSON file to SVG. With --newline-delimited, each input feature is rendered as a separate path element; otherwise, a single path element is generated. By default, the SVG’s fill is set to none and the stroke is set to black. To override these values on a per-feature basis, the following GeoJSON feature properties will be propagated to attributes: fill fill-rule (or fillRule) fill-opacity (or fillOpacity) stroke stroke-width (or strokeWidth)
