Domain coloring: plotting complex functions f(z) in the browser

An ordinary graph maps a number to a number, so a curve fits on a flat screen. A complex function maps a plane to a plane — two inputs, two outputs, four dimensions — and there's no curve to draw. So we do what mathematicians do on paper: we paint the plane.
