Hi Brad,
actually is there a schema of the graph?
you said "directed", hence there should some hierarchy in it too.'
I read there are 50K+ categories, maybe is there any list of "directions" aka "links" of how categories are connected?

Note that the "category hierarchy" isn't much of a hierarchy; it's a
directed graph with cycles and no particular root.

Your best bet is probably to download a database dump from
http://dumps.wikimedia.org/enwiki/latest/ and process it.
