about genvenn!
=============

genvenn is a D3js project to visualise list/set data comparisons with standard symmetric venn diagrams. The project is aimed at providing an opportunity for biological visualisations.

genvenn is developed based an impression of a previous project jvenn which is plug-in for the jQuery Javascript library. Some of the features in genvenn are:

* genevenn is able to visualise and compare up to 7 sets of venn diagram 
* sets upto three are incrementally visualised with circles, four, five and seven sets are visualised with ellipses, and the sixth set is visualised with standard triangles 
* venn diagram drawings are plotted following mathematical standards for their symmetry and angular alignments 
* the project requires npm packages to be used and can easily be used as sub module in other projects, 
* data can be provided as a user input, uploaded file or just loaded from a sample file for demonstration.
* genevenn is able to export all list intersection information to a file 
* it also enables exports of visual snapshots of the venn diagrams to image file.
