It may be just me, but if the number items in the set gets to numbers that require these sorts of diagrams, then the value of the visualization effectively drops to zero. I mean the purpose of data visualizations is give a human a more intuitive representational understanding of data set. A simple venn diagram does this well. But when you get 50 or 100 data sources, then it just becomes a multi-colored complexity. I mean, they look cool. But I don't gain any better understanding about the data when I look them. It may in fact make it worse because I may misinterpret the size of the areas as being meaningful when they are just necessary for geometry to work.
