NavigOWL is a visualization tool which is specially designed to explore the semantic nets a.k.a Ontologies. The Tool is enriched with appealing graph layouts that can be applied over the semantic net in order to understand the structure of Ontologies easily and it facilitates the user to build mental map in more clear and consistent view of ontology graph. The tool supports rdf and owl Ontologies to visualize them.
