Mouse & keys

click	add point
drag	add segment
Ctrl + drag	move point / endpoint (live)
right-click	delete nearest element
Shift + wheel	element weight (power diagram)
wheel	zoom at cursor
middle-drag	pan
hover	cell area, weight, group, neighbors
Ctrl+Z / Esc	undo / cancel
touch	toolbar: Draw / Move / Delete / Weight; pinch = zoom, two fingers = pan

Brownian motion and weight pulse recompute the tessellation every frame, so their speed depends on the cell count. Esc stops.

About & user manual ↗ · video tour ↗
Runs entirely in your browser (Python via Pyodide) — the same geometry engine as the desktop app. CSVs are interchangeable between the two.

drag = orbit · right-drag = pan · wheel = zoom · click = select
