Map of scientific collaboration between researchers | Stuff I made

Scientific papers are about ideas not people. Unless you're looking for a job, or a coffee shop likely to be high in PhDs, not sure this is the right projection.

How about an idea-centric map of some kind? Or place researchers in an imaginary spherical idea-space, let us see who are the stars, who are peripheral.

Anyway I think forcing the map to geography is disguising more interesting patterns.
