This visualisation shows the structure of Wikipedia category pages and their interconnections. Centered in the graph is the parent node, in this case, Humans. Pages that are linked from this parent are rendered inside the ball. Finally pages that are linked to the latter (secondary) nodes are rendered on the outer ring. Links between category pages are represented by edges, which are color coded by depth from the parent node. Nodes are clustered such that edge lenghts are minimized. This forces highly connected groups of pages to clump togheter, essentially forming topical groups.
