Did some searching today, and ran across a great example, and blog entry by Andrew Trice

I’ve always had the urge to sit down and come up with a way to do a family tree, and have images of my family and what not, and map them to each other, that way i don’t have such a hard time remembering distant relatives names at those big family reunions…

So I wanted images that drew a line to one another in a tree type structure, but wanted to to be dragable and what not… and andrew released the source for his relationship mapper, and I couldn’t thank him enough…
