All the data plus the categorisations came from dbpedia & wikidata. See this blogpost ( http://nodegoat.net/blog.s/14/a-wikidatadbpedia-geography-of-violence http://nodegoat.net/blog.s/14/a-wikidatadbpedia-geography-of... ) for a full description of how we got the data. You also find there the CSV files that we generated and used for this visualisation. The numbers reflect what has been entered into wikipedia and has been harvested by dbpedia plus data that has been entered into wikidata. So, we assume there will be a western/eurocentric overrepresentation in this dataset.
