I made two graphs of the MusicBrainz Wiki as of 13.5.04
The first map is the wiki without RecentChanges , HomePage and MuiscBrainz because these have so many links coming in and out, that it centers all other pages around them. The fact that I took these three out made 21 pages orphans .Because only the tree linked to them they are now grouped in a circle at the border of the map with no lines connecting them to the rest.
This map is still rather confusing so I made a second one:
I took out all pages that are peoples names because these centered themes around people. This is a good thing if you want to know who does what. But it is not if you want to know how the themes of the wiki are organized in respect to each other.
Taking out the personal pages made six more pages orphans
