⭕Venn Diagram Maker

About this tool

Choose two or three sets, name them, and list the items in each, one per line or separated by commas. The diagram sorts every item into the right region, matching regardless of capital letters, and shows the count for each set. A summary below lists every region in full: only in one set, in each pair and in all three. Add a title and download an SVG or PNG.

How to read and use a Venn diagram

A Venn diagram uses overlapping circles to show how groups relate. Each circle is a set; where two circles overlap are the things the sets share, and the centre of a three-circle diagram holds what all three have in common. The areas outside the overlaps hold what is unique to each set. They are a staple of compare-and-contrast essays, product and competitor comparisons, survey analysis, logic and probability lessons, and planning where responsibilities overlap. Drawing one by hand means working out the intersections yourself. Here you only list what belongs to each set, and the tool calculates the regions: an item listed under both Dogs and Cats goes in the Dogs and Cats overlap, and one listed under all three sets goes in the centre. In the example, Furry, Four legs and Playful appear in all three sets, Can be trained only in Dogs and Cats, and Loyal only in Dogs. In set notation, the overlap of A and B is the intersection, A ∩ B, and everything in either is the union, A ∪ B. Honest limits: the circles are always the same size, so the diagram doesn't show the sets' relative sizes, and each region shows a few items on the diagram with a +N more note when space runs out, though the summary lists everything. The mind map maker organises ideas and the SWOT analysis tool compares strengths and weaknesses.
