I saw this Biostar post on Venn diagrams for GO term overlap. And this tool could be modified to do something like I wish, but was wondering if there's a tool that can make nicely proportional Venn diagrams by entering just the number of elements in each set and intersection.
For instance circle A has 10 items, B has 10 items, A+B has 6 items. Drawing them proportionally would be nice, but not essential. Also nice, but not critical, would be something open source which could be integrated with a suite of Perl scripts.
P.S. not using any standard GO terms, gene IDs, etc. This is for CNVs. So elements would take the form of:
Good point! Another option to consider is UpSetR: https://github.com/hms-dbmi/UpSetR
It's a very versatile tool with helpful vignettes.
A good thought, Larry. I realize Venns are not as sexy as some. Do you have any example links from the conference (other otherwise) that would be good for showing the overlap of A,B,C or even more sets?
I'll offer you this link and the links therein: http://iphylo.blogspot.com/2011/03/some-vizbi-2011-links.html. No, I have nothing specific because I don't know how many data groupings you have and how many different overlaps. Hive plots (accessed from above link) might be a possibility. Or you could try overlapping lines, bending them as necessary to cover all overlaps.
