quantile.quantiles() Returns the quantile thresholds. If the range contains n discrete values, the returned array will contain n - 1 thresholds. Values less than the first threshold are considered in the first quantile; values greater than or equal to the first threshold but less than the second threshold are in the second quantile, and so on. Internally, the thresholds array is used with bisect to find the output quantile associated with the given input value.

quantile.range([range]) If range is specified, sets the discrete values in the range. The array must not be empty, and may contain any type of value. The number of values in (the cardinality, or length, of) the range array determines the number of quantiles that are computed. For example, to compute quartiles, range must be an array of four elements such as [0, 1, 2, 3]. If range is not specified, returns the current range.

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

d3.zoom() Creates a new zoom behavior. The returned behavior, zoom, is both an object and a function, and is typically applied to selected elements via selection.call.

d3.geoStereographic() d3.geoStereographicRaw The stereographic projection.

d3.geoInterruptedHomolosine() Goode’s interrupted homolosine projection.

d3.randomLogNormal([mu][, sigma]) Returns a function for generating random numbers with a log-normal distribution. The expected value of the random variable’s natural logrithm is mu, with the given standard deviation sigma. If mu is not specified, it defaults to 0; if sigma is not specified, it defaults to 1.

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

stream.sphere() Indicates the sphere (the globe; the unit sphere centered at ⟨0,0,0⟩).

axis(context) Render the axis to the given context, which may be either a selection of SVG containers (either SVG or G elements) or a corresponding transition.
