I made a map of Academia.SE, basing on tag co-occurrences.

enter image description here

Some more description e.g. on a respective post on meta.math.SE.

The project is on GitHub: https://github.com/stared/tag-graph-map-of-stackexchange/wiki (feel invited to tweak the plot to your taste).

I hope you like it! :)

    My first thought was, "what the what..???" My second thought was, "ooh, pretty colors." My third thought was, odd that 'professors' and 'postdocs' are in the same group as 'career' and 'career-path', but 'masters' isn't.

  • @eykanal Well, the graph is about how questions here are tagged (or mistagged). But (as I would (mis)interpret it), it's because master student ask about admissions, and not yet looking at the full carrier path (see, there is a whole group about admissions). Stranger, that 'undegraduate' are not with 'masters'... Dec 7, 2012 at 1:20

I made an interactive version of the above, with always up-to-date data, TagOverflow. You can check tag grouping - i.e. for the sake of eliminating synonyms or poorly-defined tags.

Code and a more detailed description is on Github.
