GraphViz in Protégé

Hello! Today I will show you an interesting and useful  add - on  for  Protégé.

Protégé is very useful in handling ontologies. With Protégé , you can  define hierarchies between classes and with GraphViz which can be added in Protégé   you can see a graph with these hierarchies. There are two options. In  the first, you can see only the asserted model and in the second you can see the inferred model.
This is a capture  from a graph created with GraphViz in  Protégé.



Instructions for installation:
1. You download  GraphViz from here and install it.
2. In Protege you go in File->Preferences->OWL Viz 
3. You set the Dot Application Path in dot.exe in the folder that Graphviz was installed (example: C:\Program Files\Graphviz2.24\bin\dot.exe )
