This is insanely helpful for debugging other people's code or code you've long since forgotten.

How is it more helpful for debugging compared to just looking at the git patch? As far as I can tell, this is meant to be more of a cool presentation type thing, rather than something to assist with development

Yeah, sounds like something I'd use along with Gource for presentations - gource is great for "show off our progress in the last year" in a Very Visual way (without actually being all that useful, but sometimes you need some non-technical visualizations.)

Pretty graphics and visualizations help people understand things because humans aren't LLMs. The web didn't have to evolve past having one font, black, on a white screen, but it did, because people aren't robots.

Because looking at a lot of code at once can be overwhelming, also gokng commit for commit can make it hard to track the flow of everything.
