A simple map for drawing a bifurcation diagram is the logistic map: x → a x ( 1 - x ) A zoom into the bifurcation diagram of the logistic map is shown here: Many properties of the diagram were investigated by Mitchell Feigenbaum and Robert May. A strange and significant property is the rate at which branches of the tree diagram split.
