Calculate and draw custom Venn diagrams


With this tool you can calculate the intersection(s) of list of elements. It will generate a textual output indicating which elements are in each intersection or are unique to a certain list. If the number of lists is lower than 7 it will also produce a graphical output in the form of a venn/Euler diagram. You have the choice between symmetric (default) or non symmetric venn diagrams. Currently you are able to calculate the intersections of at maximum 30 lists.
The graphical output is produced in SVG and PNG format.
Downloading the figure in SVG format will allow you to further customise it with SVG compatible software such as for instance InkScape (which is freeware).


Enter files (in plain text format!) with a list of elements and/or copy-paste lists in the appropriate fields. The lists can contain only a single element on each line, but there is no limit on the number of lines. If a line contains text seperated by spaces or tabs this will be considered as a single element (so no splitting of lines on white space). The elements are processed in a case-sensitive manner (so lowercase and uppercase are seen as two different elements)! The input lists will be processed and made non-redundant (= duplicated elements in each list will be removed such that only one remains). You can make extra fields for entering files/lists by clicking the 'Add Another ...' button. The style of the graphical output can be specified in the output control section. Choose either symmetric of non-symmetric.
Click 'submit' to start the analysis.
