D3 Color Scales: Sequential, Diverging, and Categorical Schemes D3's color system is split across two packages: (the scale objects that map data to [0,1]) and (the colormaps and palette arrays that map [0,1] to actual colors). Understanding both — and how they combine — gives you precise control over any color encoding. This guide is a practical reference covering every major scheme type with working code and decision guidance. --- Package Overview d3-scale provides: — for continuous sequential data , — log/power variants — for diverging data with a midpoint — for categorical data , , — for binned continuous data d3-scale-chromatic provides: functions — for continuous interpolation arrays — for discrete categorical and stepped palettes --- Sequential Schemes Perceptually Uniform…
