VisGraph — interactive RDF / ontology canvas

PMD

VisGraph is an interactive editor for RDF knowledge graphs and ontologies built on the Reactodia canvas. It visualises RDF subjects as nodes and predicates as edges, provides full authoring (add nodes, create and edit links, rename namespaces), applies OWL-RL reasoning with visual differentiation of inferred knowledge, and automatically clusters large graphs for readability — all directly in the browser against an in-memory RDF store backed by Web Workers.
