The ljmindmaps.com web site has somewhat oblique explanations, if you poke around. The basic idea is that the size and brightness of different names are determined by how many names of friends you and they have in common; I'm not sure what determines the position, although it's related to that, in that the 'links' show who's friends with who. It's essentially a visualization of "Six Degrees of LiveJournal."
I remember as well doing this as well once, but got sent it again in my email a week ago or so as an updated version (Just haven't posted it). Though it must go by your friends and interest lists cause I have Chipotle on mine but yet I don't see me on theirs. Then again I don't have that many LJ friends or interests.
