Re: [graphviz-interest] Dendrograms/Cladograms

Hi Hermann

Thanx. These things are definitely possible, but the question is: How 
automated can this be made?

Thinking about the cladogram, I've realized I will have to draw it on a 
virtual image, to allow negative co-ords.

This is because there's no easy way of walking the tree and determining 
how wide it will spread. And this in turn is because any internal node 
could have any number of descendants all off to one side, like a giant 
list of cascading 'L' chars.

After that initial plot, I (if I write this!) will simply scale all 
co-ords so the minimum is 0, or some small number, to push the image 
away from the frame.
