Incredible what Mermaid can display. I used to use d3 for graphs. But this is exactly what I need: display a diagram based text expressing relations instead of all kinds of graphical properties.

Great

Spent a day trying to get mermaid to render. For some reason, it did not create a merpress block when I first created it. However, I retried a few hours letter and it worked and worked like magic. Thank you for working on this.
