Re: Romerograms

Here is a blog post and a lengthy thread on the 1932 "histomap".

Romerograms are similar, but have a much more explicit phylogenetic 
component, and the "relative dominance" is (if at all) labeled "diversity" 
even though it is practically never a species, genus or even family count 
(almost always the mammal bubble is broader than the bird bubble, the edges 
are smooth and rounded instead of pixelized, and so on).
