Fun with graphs

I love David McCandless's Information is Beautiful, which is full of beautiful graphs.  I'm a nerd so it's totally my bag, baby.  Some of my favorites include Colours in Cultures and Time Travel in Popular TV.

He recently posted about the Varieties of Intimate Relationships and included a nod to Franklin Veaux's Map of Non-Monogamy, below.  I'm definitely a monogamist so I can't say I identify with this, but as a chart, it's pretty epic.
