A Mesmerizing Map of the Global Arms Trade


This has apparently been around for a while but it’s one of the most impressive data visualization projects I’ve seen in a while. Mapping Arms Data is an interactive animated map created by Brazil’s Igarapé Institute together with Peace Research Insitute Oslo and Google Ideas that lets you see where countries are buying and selling their small arms and in what quantities. It takes a while to load but is well worth the wait.

The project recently won a data visualization competition and the creators were interviewed by the BBC here.
