Diagrams
Fence a block with ```mermaid and wander draws it. Click a diagram to edit its source; the toggle in the corner switches between the drawing and the text. Everything renders on your Mac, no network, and the file stays plain markdown any tool can read.

A diagram of its own
A diagram does not have to live inside a note. Save one as a .mermaid file and wander opens it as a diagram, with its source beside it: see pipeline. The eye and split buttons switch between the drawing and the text, exactly as they do for a typst paper or a csv.
.mmd files open the same way. They stay plain text, so mermaid.live, GitHub and everything else read them unchanged.
