A map of the world visualising the connections between Facebooks users has shown just how far friendships can reach.
The infographic image, created by Facebook intern Paul Butler, maps out the world based on Facebook usage. The image itself appears like a view of the earth from space, although with tiny lights marking the location of users.
The image was created from a sample of 10 million Facebook users. This was then mapped based on the user’s location and the locations of his/her friends, before then being set on points of latitude and longitude.
Writing on the Facebook blog where he first posted the map, Butler said: "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".
"It's not just a pretty picture, it's a reaffirmation of the impact we have in connecting people, even across oceans and borders".
