I only use diagramming tools with automatic layout algos to generate visualizations programmatically to debug things. For documentation purpose, I largely prefer to draw them by hand using OmniGraffle, because making graphs look nice using tools like graphviz is very complex and you find yourself abusing features to hack your vision into reality

What's dearly needed in my opinion is a graph layout algo based on a machine learning model (so that it can take into account readability and aesthetics). Unfortunately what I found so far is mostly concerned with displaying large graphs, which is kind of another domain altogether.

I hope Mermaid is collecting every single edition point that happens on their UI, that would make for a nice dataset I guess.

I settled on excalidraw via obsidian

This is really impressive! Excalidraw does some great work. Did you try Mermaid's integration with Obsidian? What was lacking and what ultimately hooked you on Excalidraw?

I do use mermaid quite a bit in markdown because it's documentation/code that can be updated, the idea tends to start in my notes as excalidraw, and eventually become a mermaid graph. I wouldn't say it's lacking anything. I have not tried it so I can't a valid opinion, but I am happy to give it a try and give some feedback. I do waste time converting. I see a couple of tools, do you recommend one in particular?
