d3.schemeSet1 An array of nine categorical colors represented as RGB hexadecimal strings.

d3.scaleImplicit A special value for ordinal.unknown that enables implicit domain construction: unknown values are implicitly added to the domain.

d3.interpolateSpectral(t) d3.schemeSpectral Given a number t in the range [0,1], returns the corresponding color from the “Spectral” diverging color scheme represented as an RGB string.

log.interpolate(interpolate) See continuous.interpolate.

quantize.tickFormat([count[, specifier]]) Equivalent to continuous.tickFormat.

d3.forceY([y]) Creates a new positioning force along the y-axis towards the given position y. If y is not specified, it defaults to 0.

request.responseType([type]) If type is specified, sets the response type attribute of the request and returns this request instance. Typical values are: ​ (the empty string), arraybuffer, blob, document, and text. If type is not specified, returns the current response type, which defaults to ​.

d3.geoHealpix() d3.geoHealpixRaw(lobes) The HEALPix projection: a Hierarchical Equal Area isoLatitude Pixelisation of a 2-sphere. In this implementation, the parameter K is fixed at 3. Note: requires clipping to the sphere.

zoom.on(typenames[, listener]) If listener is specified, sets the event listener for the specified typenames and returns the zoom behavior. If an event listener was already registered for the same type and name, the existing listener is removed before the new listener is added. If listener is null, removes the current event listeners for the specified typenames, if any. If listener is not specified, returns the first currently-assigned listener matching the specified typenames, if any. When

node.eachBefore(function) Invokes the specified function for node and each descendant in pre-order traversal, such that a given node is only visited after all of its ancestors have already been visited. The specified function is passed the current node.
