Diagrams

58 drawings. 36 include a moving dot. Reduced motion hides the dot.

Learn it in 5 minutes

Each drawing has three files: an SVG, a PNG of that SVG, and a standalone HTML page. The disclaimer is inside all three.

A moving dot means reading order. If you asked the browser to reduce motion, the dot is hidden and the boxes stay.

Counts on a chart are from the JSON files. A mind map is a map of this app, not a claim about history.
