The legal map is an effort to map the often confusing, contradictory and convoluted world of international law, answering questions like "who's a signatory of this treaty?" or "which countries still use the death penalty?".
It can be viewed online at legalmap.robm.me.uk.
The legal knowledge was assembled and painstakingly converted to JSON format by Gillian McCall; the site was coded by Rob Miller.
