About this Application
This site contains 8095 articles from the math encyclopedia PlanetMath.org — the only thing we added is a navigational panel on the left, where some metadata about each article is displayed.
Especially we computed the pagerank of each article and clustered them into 36 chunks, which we call chambers here. If an article is e.g. in the first chamber, it indicates a kind of higher importance (within the universe of the PlanetMath.org articles) than an article in say chamber 20. Additionally incoming and outgoing links are displayed for each article, sorted by their pagerank/chamber.
The current version uses the snapshot from January, 12th 2009.

Adjacency Matrix
The following two images visualize the link matrix. The dots are scaled (by factor 100), since the matrix is sparse. In the first picture, the articles are ordered by pagerank; in the second the order is as random as the database importer script.
