Zovo Venn
Venn diagrams from 2 or 3 lists, with each item in its region.
Zovo Venn compares 2 or 3 lists and draws a Venn diagram. Give it named lists of items, up to 500 per list, or only the region counts. It finds which items are only in one list, in two lists or in all three, counts each region, and draws the items inside their region when up to 12 fit at a readable size. Larger regions show their count, and the CSV and the PDF item pages list all items. Circles are the same size by default and the result says the areas are not to scale; for 2 lists you can choose circles whose areas match the counts. Download a vector SVG, a one-page PDF and a CSV with each item's region.
What it does
- 2 or 3 lists of up to 500 items each, or region counts only
- Stated matching rule: Unicode and space clean-up, case ignored unless you ask, repeats counted once
- Items drawn inside their region, checked against the circle equations
- Symmetric circles, or area-proportional circles for 2 lists
- Vector SVG, PDF and a CSV with each item's region
- A region table with counts and overlap percentages, without a diagram

Limitations
- 2 or 3 sets; up to 500 items per set and 80 characters per item
- Symmetric circles are not to scale; proportional circles are offered for 2 sets only
- The PDF font covers Latin, Greek, Cyrillic and Vietnamese; Chinese, Japanese, Korean, Arabic, Hebrew and emoji show as ? in the PDF (the SVG and CSV keep them)
- Lists are not kept after the call. Download files of large diagrams are stored for 1 hour and then deleted; download them to keep them
