[protege-discussion] error displaying ontology using OntoViz

[Rajesh Kumar]

Hi,

Thanks for the reply. I added the path to the "dot" executable but I 
still get the same error message.

I confirmed that "dot.exe" is on the path by opening a command window 
and running "dot" from the command line.

Anything else that might be wrong?
