What Hacker News says
5 sourcesThis is pretty cool!
Reminds me of the now defunct SourceTrail tool: https://github.com/CoatiSoftware/Sourcetrail
Actually, seeing lines between the code and where you opened it from would most likely be useful!
In Show HN: Haystack – an IDE for exploring and editing code on an infinite canvasThis appears to be the only fork that's at least somewhat active: https://github.com/OpenSourceSourceTrail/Sourcetrail
But overall, there is little activity in any of the forks, without anyone necessarily spearheading the effort: https://github.com/CoatiSoftware/Sourcetrail/forks?include=a...
In We need visual programming. No, not like thatBy chance did you mean Sourcetrail [1] instead of Sourcegraph? Old demo video on YouTube: https://youtu.be/Cfu6f0uyzc8?si=oNS9KKlbgEk_Ct0p.

In An infinite canvas for code explorationI wish something existed in this space. I used Coati Software's Sourcetrail for a couple of years. Unfortunately it was discontinued. It was a wonderful piece of software that indexed a code repository, and exposed an interface to explore it interactively. At least for me, it significantly improved the understanding and legibility of code.
The code is in an archived state (https://github.com/CoatiSoftware/Sourcetrail). Searching for the software on Google shows some screenshots.
In Ask HN: Anyone use a code to mindmap/flowchart tool?
