Venn Diagram Generator
Enter item lists for two or three sets — or raw region counts — and get a labelled 2- or 3-circle Venn diagram with the real intersections computed and a full region breakdown.
Start each set with == Name, then one item per line. An item appearing in several sets moves into the matching overlap region. Case and spacing are compared exactly.

About this tool
The Venn Diagram Generator works out every region from your item lists, so an item present in more than one set lands in the correct overlap — or you can type the seven (or three) region counts directly. In area-proportional mode the radii follow the square root of each set size and the centre distances are solved numerically so each intersection lens has the area its count implies, with the triangle trimmed back if no exact solution exists. All parsing, geometry and PNG export happen locally in your browser.
