Random Traversal III, Mike Bostock, 2014-6

A spanning tree of the canvas is generated using random traversal and then flooded with color. The hue (color) illustrates the rectilinear distance from the root of the tree. i.e., color illustrates the distance from the origin when navigating the edges of the maze. Bostock notes that this isn’t an optimal visual encoding, but that it is sufficient and pretty (!).
