Compare distributions of values across multiple n, es settings

[gussmith23]

I realized when I saw slide 9 of this presentation that it would be useful to look at value distributions between different settings of n and es---it would actually be a lot more useful than some of the other stuff we do!

[gussmith23]

if we build the histogram along the circle, that'll be a good start. By flipping between different settings of n and es, the users can compare. What would be even cooler, though, would be if they could overlay two histograms at once---e.g. if we could support two (n,es) settings on single circle!

For reference, I would like to, for example, overrlap multiple histograms for different (n,es) settings.
