Re: [graphviz-interest] Dendrograms/Cladograms

If we add   {rank=same; A B C D;}, to the mix we can get the text to line up.  
But even after lots of fiddling, I could not get it to look ready-for-publication.
For fun, I decided to try it in PIC (compiled it to svg with pic2plot)

Works like a champ & easy to automate
