Check out this really cool infographic an intern at facebook put together.

It’s an amazing visualization of Facebook friendships which actually maps out the world. It was created by Facebook intern Paul Butler.
I began by taking a sample of about ten million pairs of friends from Apache Hive, our data warehouse. I combined that data with each user’s current city and summed the number of friends between each pair of cities. Then I merged the data with the longitude and latitude of each city.
If this is what the interns at Facebook can do then the company has an amazing future ahead of it. (Like we didn’t know that anyway….!)
