I don’t actively use Mermaid graphs, so it’s not on my short term roadmap, however here’s what you can do:
- Grab the sample CSS from Mermaid documentation
- Save it as an Obsidian snippet
- Customize it. I recommend using the same kind of color build up you see near the top of the Minimal theme file (around lines 164-256) so that it adapts to your accent color
- Share your snippet in Share your Minimal Theme screenshots/configuration
