About Venn Maker

Venn Maker is a free online Venn diagram generator. Instead of dragging circles around, you describe how your sets relate and the diagram is laid out automatically. No sign-up is needed, and what you enter never leaves your browser.

How to make a Venn diagram

  1. Enter the names of your sets (e.g. Animals, Mammals, Birds).
  2. Choose how each pair of sets relates: "is contained in", "partially overlaps", "does not overlap" or "is the same as".
  3. Optionally label an overlap (e.g. Birds ∩ Flying animals = Swallow).
  4. Save the diagram as SVG or PNG, or export it to Mermaid or draw.io.

Features

  • Infers containment, overlap and separation from your relations, and points out contradictions
  • Automatically picks the clearest shape: circles, ellipses or rounded rectangles
  • Up to 20 sets, with a color of your choice for each
  • SVG / PNG download, Mermaid (venn-beta) code and an editable draw.io diagram
