Venn diagram tool
Paste newline-separated strings into each list. Overlaps follow exact string equality (trimmed lines). Use two or three lists for circle diagrams; four use four rotated ellipses (Venn construction); five to eight use an UpSet-style intersection plot plus the same table.
Two or three lists draw classic circle Venns. Four lists use a four‑ellipse Venn plus the table. Five to eight use an UpSet-style plot (dots per list, lines for overlaps). Removing rows stashes their fields; adding rows restores in reverse order. + / − match this dropdown.
