Recently, i was on [Philpapers](http://philpapers.org/) searching for references on their [categorie page](http://philpapers.org/browse/all). The completness of their taxononmy was striking and I thought : "Could it be possible to map this taxonomy ?".
I decided it was a nice idea and i started to work on it.
The first step was to select the kind of graph and since their taxonomy includes a hierarchy permitting to sub-categories to be children of more than one parent categories, I selected a concentric circles graph.
Because I'm a python user, I choosed Networkx for the graph part and BeautifulSoup for the scraping part. Furthermore, since Philpapers gives the articles number for each category, I decided to add this data to my graph.
After some configurations of the display, I finally reached my goal : **a map of the taxonomy of philosophy**. And it was quite beautiful.

**Map Legend :**
* Size of nodes : number of articles in this node.
* Relations between nodes : parent/children relation between categories.
