Some time I created A Graph Map of Math.SE, which met with a warm response from this community. Encouraged by this, I created a new visualization, this time interactive and up-to-date (as long as the SE API lives): TagOverflow. For Math.SE, it is: http://stared.github.io/tagoverflow/?site=math&size=32. Code and description is here.
Besides looking at the graph, you can:
- get interesting information per tag,
- get some statistics (like average score for these tags).
I hope you enjoy it!
EDIT: I am waiting for your insights and ideas how to improve it. (It my be good to post these as "answers".)
