Venn Diagram Maker

Paste two or three lists or enter counts. See every overlap.

Paste one item per line into each list, for example gene symbols. The tool removes duplicates, finds the items unique to each set and shared between sets, draws a 2 or 3 set Venn diagram with the count in every region, and lists the items in each region. You can also type region counts directly. Export the diagram as SVG or PNG and the region lists as CSV.

Questions

How do I make a Venn diagram from two lists?

Choose 2 sets, paste one list into each box with one item per line, and the diagram shows how many items are only in the first list, only in the second, and in both. The items in each region are listed under the diagram.

How do I find the overlap between gene lists?

Paste each gene list into its own box. The region in the middle shows the shared genes, and you can copy that region's genes with one click. Turn on Ignore case if the lists mix upper and lower case symbols.

Can I make a 3 circle Venn diagram?

Yes. Pick 3 sets. The diagram shows all seven regions: three unique regions, three pairwise overlaps and the center shared by all three.

Are the circles drawn to scale?

No. The circles are a fixed size so every region stays readable. The number in each region gives the exact count.

Can I enter numbers instead of lists?

Yes. Switch Input to Counts and type the number of items in each exclusive region, for example A only, B only and both. The set sizes are summed for you.

Are duplicate items counted twice?

No. Each list is deduplicated before comparing, so an item that appears twice in one list counts once.
