The article introduces jvnn, a new JavaScript library for creating interactive Venn diagrams. Venn diagrams are commonly used to compare biological data, such as gene lists from different differential analyses. However, when the number of input lists exceeds four, the diagrams become difficult to read. jvnn addresses this issue by handling up to six input lists and providing both classical and Edwards-Venn layouts. The library allows for user interactions and customization, making it easier to interpret the data. jvnn can be easily embedded in web pages, enhancing the readability and usability of Venn diagrams. The authors highlight the advantages of jvnn over existing software, such as VENNTURE, which only supports up to four lists and is limited to static outputs. jvnn is open-source and freely available, with full documentation and examples provided. It has been used in several scientific publications and integrated into various web applications. The article also includes a detailed implementation guide, results from a practical application, and a comparison with other tools.The article introduces jvnn, a new JavaScript library for creating interactive Venn diagrams.
