It was designed to visualize RDF data sets in particular, but could be tailored to almost any data source by implementing a data provider interface.

Core features

  • Rich graph visualization and context-aware navigation features
  • Ability to store and retrieve diagrams
  • User friendly - no graph query language or prior knowledge of the schema required
