Data Visualization

You can see two visualizations data of our small arms trade data.

The Mapping Arms Data (MAD) visialization is run in conjunction with the Igarapé Institute and is based upon a past association with Google Ideas. It is best viewed in an up to date version of Chrome or Firefox. It will not run in Internet Explorer.

The NISAT Arms Trade Mapper was developed by the Peace Research Institute Oslo and Julian Wagstaff. It can be viewed by all widely used browsers, and in addition is recommended for those with a slow internet connection.

It displays the top ranked importers and exporters, exports and imports by country, and users can select to view a country's exports to destinations involved in war, huiman rights abuses, high levels of homicide and low GDP per capita.
