D3.js Scale Chromatic

This module provides sequential, diverging and categorical color schemes designed to work with d3-scale’s d3.scaleOrdinal and d3.scaleSequential. Most of these schemes are derived from Cynthia A. Brewer’s ColorBrewer. Since ColorBrewer publishes only discrete color schemes, the sequential and diverging scales are interpolated using uniform B-splines.

Allows you to produce sequential color schemes.
