Produce Venn (?) Diagram / Intersection Numbers

[palexiou]

1. Out of all the existing genes in the dataset: (%)
   How many does each algo cover?
   How many are covered by each 2-algo combination?
   How many are covered by all algos?

-> make a table so we can pick what numbers to mention in the text.

Would it be possible to make a venn diagram that looks OK?
