All the data plus the categorisations came from dbpedia &amp; wikidata. See this blogpost ( <a href="http:&#x2F;&#x2F;nodegoat.net&#x2F;blog.s&#x2F;14&#x2F;a-wikidatadbpedia-geography-of-violence" rel="nofollow">http:&#x2F;&#x2F;nodegoat.net&#x2F;blog.s&#x2F;14&#x2F;a-wikidatadbpedia-geography-of...</a> ) 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.<p>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&#x2F;eurocentric overrepresentation in this dataset.
