InteractiVenn allows users to create Venn diagrams based on list unions or tree unions. Users can now show percentages instead of just counts, and mouse-over numbers will now highlight their sets. A new feature allows users to export diagrams and edit them further in Inkscape. This tool was developed by Heberle, Meirelles, da Silva, Telles, and Minghim and is a helpful resource for set analysis. Please cite their work if you use their tool.
