A wicked visualisation of the Global Arms trade. Saw on a website this morning but I can't remember which one. Either way, it's well worth a look. It doesn't make for particularly surprising viewing though... obviously the data isn't all there. There are some big bright lines missing leading out from Russia I think.... I am sure the UK's could be a little more colourful than it lets on too.
I think it could more accurately be called, the (Declared) arms trade.
