How to create a mindmap with Mermaid

Open FlowViz and type mindmap.

Define the root node on the next line: root((My Topic)) for a circle shape.

Add first-level children by indenting with 2 spaces: child topic.

Add deeper levels by indenting further — each indent level is a child of the line above.

Use ((text)) for circles, [text] for rectangles, (text) for rounded rectangles on any node.
