This map shows half a million London Underground journeys in under two minutes

This visualisation shows 562,145 people moving around the Tube network's 11 lines based on a sample of Oyster card data during a week in 2009 - each dot on the map represents one journey.

Will Gallia, a 26-year-old from Haggerston who took three years to create the video, told the Evening Standard that he was surprised its appeal went beyond computer programmers and graphic designers.

It’s weird that it resonates with people. Even the simplicity of the dots thing – people like the idea they’re represented by a small point.
