So I got to thinking, since I'm on this pie chart kick, "what would be the worst pie chart ever?" And I decided it would be a Venn diagram made with pie charts. I laughed to myself, imagining such a creation. Then I thought, somebody's probably done this. And indeed, there's an app for that.
At long last, the power of Venn diagrams and pie charts combine to turn the world of mathematics on its head! If you've ever felt the need to create Venn diagrams with pie charts, or wished your pie charts could overlap to provide even more informative data, then Venn Pie-agrams is the app for you!
I'll leave it at that.
