Ontology visualization

Ontologies are often represented as a graph where nodes represent objects within given ontology and edges represent relations between those objects. Such graphs can be very complex even for medium sized ontologies so a clean and complete graphical representation is needed. Existing solutions do not include all elements or produce unreadable results for big ontologies. In this paper a complete set of graphical objects for ontology representation was proposed. Algorithms for graph creation were defined. An implementation of proposed solution is described. Comparison with other solutions is made.
