I have jumbled together this list. When I started putting it together there were lists if only about 10 well known tools. Most of the tools here are from HN comments and I just kept adding to it over time.
Yeah I stole the link for this submission from your comment[0] as it's extremely useful and I wanted to make sure I don't lose it. I need to do a diagram every couple of months and I hate GUI-only tools, and the ones I used in the past seem to be no longer maintained. Also, some of these do just one job well, so for a different type of diagram I need to look for another tool. Your list is a nice summary, thank you.
This is incredibly useful and interesting. I have tried asking claude to generate XML code for various diagrams for import to draw.io with varying success. But I feel like if I could incorporate these instead, or markdown, for a specific graph instead of pure XML would yield better results.

Ever since Github added native support for mermaid, that's all I really use.
