Map of Facebook friendships shows connections across the globe

Melbourne, Dec 15 (ANI): Ever wondered how the world would look like through Mark Zuckerberg's Facebook eyes? Well, an intern with the social networking giant has created a map of the world by joining the dots between friendships.

The eastern half of the US, Europe and parts of Indonesia shine the brightest, while China, Russia and central Africa are mainly dark.

Paul Butler, an intern with Facebook's data infrastructure engineering team, said the map was based on about 10 million friendships.

"I began by taking a sample of about 10 million pairs of friends from Apache Hive, our data warehouse," quoted him as writing in a post on Facebook.

"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," he wrote.

Butler said he was surprised when he first saw the project worked and the lines took the form of a map of the world.

"Not only were continents visible, certain international borders were apparent as well. What really struck me, though, was knowing that the lines didn't represent coasts or rivers or political borders, but real human relationships.

"Each line might represent a friendship made while travelling, a family member abroad, or an old college friend pulled away by the various forces of life," he added. (ANI)
