Visualization Graph of Artists, Writers, Thinkers

This visualization graph was featured on BoingBoing. It plugs itself as a "Genealogy of Influence," showing the connections among 500+ of " the most influential writers, artists, philosophers, scientists, and mathematicians of Western culture."

I found it a bit hard to navigate on the fly -- the lines get kind of tangled. But I'd love to have this on a poster as a conversation piece.
