Thanks Danny, no modesty here though.  I am pretty confident that 
TouchGraph should only be used when dealing with non-hierarchical or 
multi-hierarchical data.  Plain hierarchies would best be displayed with 
other tools such as inxight or http://www.elastictech.com/html/demos.html    (02)

However, on further experimentation with www.vivismo.com , I realized that 
the tree view on the left (which is expandable) actually has some repeating 
websites at the leaves, which would in fact make it a good candidate for 
display with TG.    (03)

Speaking of Topic Maps, here is advanced notice about two TouchGraph based 
tools that recently came out:    (05)

http://www.tm4j.org/tmnav.html TMNav a topic map visualizer (Download a 
usable demo from sourceforge )

Good link, and good to hear about the CMap's switch to XTM.    (08)
