Thanks Harvey, There are certainly many ways to approach this visualization. I took a shot at the approach you described (at least I think I came close to it) and the result is on the Plus (+) Jwiki NuVoc: http://www.jsoftware.com/jwiki/Vocabulary/plus I added a vector component and still came in under 30 seconds. Let me know what you think.
