create a branching tree diagram

[don_s]

I am trying to create dynamic diagrams from database queries that branch like evolution daigrams similar to this page http://tolweb.org/tree?group=Eukaryotes&contgroup=Life
except I want the nodes to be links for drilling down, and the branches able to change based on new input/changes in the DB.
My initial thought was to use images of lines and forks inserted in table format as needed.
Any ideas how I could do it easier/better?

you could use a Java applet driven by a set of dynmically generated params or a flat file serverside... It exists and it works well (sometimes...).
If you want to do it 100% PHP, I know some people have developed this code but it's a DB IO vampire... will try to locate the link to source...

Good luck anyway

U can Use GD Library functions and draw any tables U like, after generating it U can use map to make needable elements as link.
