Facebook’s intern Paul Butler made an attempt to visualize data on Facebook connectivity. In the blog he wrote ‘When the data is the social graph of 500 million people, there are a lot of lenses through which you can view it. One that piqued my curiosity was the locality of friendship’.
Butler took a sample size of ten million pairs of friends from Apache Hive, Facebook’s data warehouse and then combined that data with each user’s current city and summed the number of friends between each pair of cities.
The outcome of this study represented relationships on a world map, that apart from being a picture that is beautiful and an image of how people of the world are interconnected, it also reaffirms the fact of how widespread an impact Facebook has in today’s internet world.
