After seeing this, the good moderator @Alenanno requested me to make a similar map for Linguistics.
I present to you:
Tag size is proportional to tag popularity, and the size of links between tags is proportional to the amount of times they are used together. The tags are approximately clustered according to frequency of use together, and the colors help visualize the clustering.
