I just discover another way too. Visual studio code plus markdown preview enhanced. With vim mode you got pretty much the same thing.

For the developers among us that is just one plugin away.

This plugin just shows you the graph, right? VNote can scroll the corresponding element into view and highlight it, which is very helpful when the class diagram is really large on a small screen.

By the way, when you double click an element in the preview graph, VNote could highlight the originating definition code in the editor.

The Live Preview Tunnel, I think, is what makes VNote different from other editors. :)
