The BBC’s visualization below would be beautiful were it not so tragic. It’s a map visualizing traffic casualties between 1999 and 2010. Each light point on the map represents more than 2 million road collisions that resulted in a casualty; the brighter the light, the more frequently collisions occurred in that spot.

Along with the map, there is also a haunting time-lapse video animation of the crash data.
