I noticed this wonderful tag cloud describing the interconnecton of topics on Math Stack Exchange. I recall seeing tools like this on the internet. I don't recall if Stack Exchange itself generates such charts.

Stack Exchange Data Explorer certainly did not turn up anything graphical.

I recall there being an online service which generated such charts, but I don't remember if it was directly affiliated with Stack Exchange or not.

As far as I know, this originated with some code by Piotr Migdal several years ago on Math Stack Exchange (with at least one update). The project was independent of Stack Exchange, and eventually was applied to other sites (e.g. Physics), becoming the fully interactive Tag Overflow, letting you generate your own graphs for various sites. There are also even bigger maps.

It gets data via the Stack Exchange API.

  • not exactly life-changing but extremely informative nonetheless. This was exactly the one. Thanks. Oct 18, 2016 at 12:24
