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. Sequential Schemes Perceptually Uniform (Recommended) These are the go-to options for sequential quantitative data. All are perceptually uniform — equal data steps produce equal perceived color differences. interpolateViridis — yellow to purple-blue via green. Best all-around choice. interpolatePlasma — yellow to magenta to purple. High contrast, vivid.…
