I have been looking for a tool that will visualize traceroute data in
a graph. Skitter looks ideal, but its availability is quite limited. 
 
I have tried Netmap (netmap.sourceforge.net) and have been
mucking about with Graphviz (graphviz.org) in general.
However, the problem of building a map from traceroute data
(with graphviz anyway) is sorting out the unique paths. Technically
possible, but I don't want to re-invent the wheel if I don't have to.
 
Tulip (tulip-software.org) is a framework that something like this
could be written in, as is any other viz tool (opendx.org, etc...)
The tools from Opte (opte.org) aren't available yet. 
 
Is there a tool that you are currently using to represent large
traceroute graphs that is available under a gpl/bsd/open license?
Even something based on Dot or Neato?
 
Thanks,
