d3.curveBasis(context) Produces a cubic basis spline using the specified control points. The first and last points are triplicated such that the spline starts at the first point and ends at the last point, and is tangent to the line between the first and second points, and to the line between the penultimate and last points.

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.csvParseRows(string[, row]) Equivalent to dsvFormat(",").parseRows.

d3.csvParse(string[, row]) Equivalent to dsvFormat(",").parse.

d3.csvFormatRows(rows) Equivalent to dsvFormat(",").formatRows.

d3.csvFormat(rows[, columns]) Equivalent to dsvFormat(",").format.

d3.csv(url[[, row], callback]) Creates a request for the CSV file at the specified url with the default mime type text/csv. An optional row conversion function may be specified to map and filter row objects to a more-specific representation; see dsv.parse for details. For example: function row(d) { return { year: new Date(+d.Year, 0, 1), // convert "Year" column to Date make: d.Make, model: d.Model, length: +d.Length // convert "Length" column to number }; } The row conver

d3.creator(name) Given the specified element name, returns a function which creates an element of the given name, assuming that this is the parent element. This method is used internally by selection.append and selection.insert to create new elements. For example, this: selection.append("div"); Is equivalent to: selection.append(d3.creator("div")); See namespace for details on supported namespace prefixes, such as for SVG elements.

d3.color(specifier) Parses the specified CSS Color Module Level 3 specifier string, returning an RGB or HSL color. If the specifier was not valid, null is returned. Some examples: rgb(255, 255, 255) rgb(10%, 20%, 30%) rgba(255, 255, 255, 0.4) rgba(10%, 20%, 30%, 0.4) hsl(120, 50%, 20%) hsla(120, 50%, 20%, 0.4) #ffeeaa #fea steelblue The list of supported named colors is specified by CSS. Note: this function may also be used with instanceof to test if an object is a color instance. The same

d3.cluster() Creates a new cluster layout with default settings.
