Another cool data visualization tool. This one graphs out your friend network from Facebook. Here's my friend graph. It's is pretty cool how neat clusters are formed between different sets of your friends, like your old school buddies, undergrad/grad school friends, work friends/colleagues etc. And how some people act as "Connectors" across multiple groups. Studying social graphs has been around for a while now, and it is nice to have simple visualization apps which everyone can use easily.
