It is similar, except with a lot of fractals, the numbers being colored represent how many iterations are required to get outside of a set threshold (which indicates divergence).

Right, I just meant more that you plot more than just the equality to get some visualizations. Is also a common way to visualize game theory stuff, I thought. You want to know where the expected equilibrium is, but you also want to see, essentially, what the strength of getting there is.
