Venn Diagram Generator

This visual set theory tool creates Venn diagrams with two or three overlapping circles, letting you define set labels, populate regions with items, and customize colors and sizing. The renderer uses SVG-based drawing to produce crisp, resolution-independent diagrams that scale cleanly for both screen display and print. Circle positions and overlap areas are calculated using geometric intersection formulas to ensure visually accurate proportional representation.

The tool supports interactive editing where you click on specific regions to add or remove items, and it automatically calculates intersection and union populations based on your input. Export options include PNG for presentations, SVG for further editing in vector graphics software, and direct copy-to-clipboard for pasting into documents. You can customize fill colors, opacity levels, stroke widths, font sizes, and diagram titles.

Students completing math assignments, teachers creating instructional materials, business analysts visualizing market overlaps, researchers illustrating dataset relationships, and presenters adding visual aids to slides all use this tool to create professional diagrams instantly. The entire rendering pipeline runs in your browser using client-side JavaScript and SVG, so your data never touches a server.
