How it works
- Paste up to four lists on the left (one element per row)
- Click a number in the diagram to list its elements in the Results panel
- Pick a style then export SVG / PNG in one click
- Drag any label or number to reposition it; double-click to reset. Use "Find an element" to highlight where an item sits
- Tick "Area-proportional" so every region's area matches the number of elements it holds
