The two figure I attached show overlaps between 10 sets, 22 sets. i think it is impossbile to draw venn diagrams for so much sets.

It's worse than that: it is impossible to draw exact, area-proportional Venn (Euler) diagrams with circles for even *three* sets, though approximations are widely available. By loosening the circular constraint of an Euler diagram, a group at Microsoft Research came up with a fan-shaped diagram (also called a "ConSet") that provides precise area-proportionality. Their paper describes the issue in more detail: http://research.microsoft.com/pubs/64283/iwc2007-conset.pdf

Venn diagrams are good when it is visible all possible overlaps between every set. It gets tricky once you have more than 3-4 sets, maximum of 11 can be done - http://www.wired.co.uk/news/archive/2012-08/10/11-set-venn-diagram

9.7kFor more than 4 sets I use VennMaster which does a reasonable job of approximating proportional overlap. See Tool To Generate Proportional Venn Diagrams? for all kinds of other Venn diagram suggestions.
