VennPlex example with tri-venn diagrams, see text below.

VennPlex is a novel Venn diagram generating tool that can separate factors between two to four input datasets. VennPlex has been designed to separate data which possesses a sortable denominator (e.g. official Gene Symbol) with an associated variable numerator (e.g. z-ratio value). VennPlex can separate denominators between sets and also demonstrate the differences in the numerator values for denominators common to multiple set intersections that possess distinct numerical values. Data can be uploaded into VennPlex from spreadsheets. The VennPlex application allows multiple modes of Venn diagram set image generation with an additional ability to export intersection numerical variation data to Excel™ spreadsheets. While currently only available on Microsoft Windows, we intend to develop a running platform-independent version of VennPlex.
