Interactive Venn diagrams using JavaScript
Fri, 06/01/2007 - 23:13 — dwees
A colleague of mine at work showed me a Java applet where the user could see various sets represented using Venn diagrams, and I decided to build something similar in JavaScript. I was going to do it in Flash, but JavaScript was easier to debug (especially given that I didn't have a copy of the Flash editor available to me at the time).

Venn Diagram script
The part that made coding this script easier was the realization that all I had to do was create the partial images, then use bit-wise logic to decide which images to show. Basically I created a bunch of images, each representing the different distinct parts of the Venn diagram and then I overlay them to show the resulting set. So then I don't need the computer to know the sets at all, I just need to make sure I know the sets.
