I was just about to write this feature requests, this would be amazing.
It would allow for extremly visual and creative ways to display the relationship between notes. It will also allow to create some amazing visual workflows and take mermaid to a whole new level.
There seems to be a really cool post on a workaround way to achieve it
Unfortunatly, with obsidian 0.9.3 it doesn’t seem to work anymore
Would love to see this implemented if possible, thanks
