Asking here (also cross-asking at cstheory.meta.SE) because I couldn't find contact information for anyone at StackExchange who looked like they could help with this.
UX.SE has Balsamiq mockups built-in, since mockups frequently appear as images in questions or answers anyway and it's convenient to have them editable directly in the Q&A interface to avoid copy/pasting images back and forth. For similar reasons LaTeX math markup is enabled on a variety of SE sites.
I work at a company that specializes in graph drawing and interactive editing of graphs. We do have two interactive graph editor applications, a Java-based desktop application, and a browser-based one. I thought it might be nice to have such a capability for drawing graphs directly within questions/answers as well, similar to how Balsamiq mockups is integrated. Looking through posts tagged graph-theory that have images there's quite a wide variety in how those are created:
- Some screenshots from LaTeX-typeset documents
- A few drawn in Paint, or Office
I believe many of the images that are not taken from somewhere else (and thus would have been created on the fly for that question/answer) could be comfortably created by such a tool, perhaps with some editing aids specifically aimed at graph types commonly used in this context here.
Just wondering whether such a thing would actually be welcome or considered useful here. Actual integration and creating the editor would be a different problem entirely and maybe the Stack Exchange staff has strong opinions in this regard as well.
