Wikipedia Category Graph Generator

I was in the process of trying to understand the classification schemes available in Wikipedia (categories, lists and navigation maps) when I came across this nifty tool. It is very useful to understand the inter-relationships between Wikipedia categories.

  1. The important thing to remember about the en:wp category scheme is that it doesn’t necessarily make sense, and there’s no reason or authority to make it make sense. This is unfortunate …

    There is talk of a more tag-like scheme for categorisation, where most subcategories would disappear to be replaced by a query on the intersection of two tags. But someone has to write the code, and show it won’t slow the database to a crawl in practice.

Also the cloud graph layout (alternative algorithm checkbox) tended to work better for me, as the default tree-style layout generated very wide graphs. Here’s an interesting looking graph:
