PROV-O-Viz - Understanding the Role of Activities in Provenance

This paper presents PROV-O-Viz, a Web-based visualization tool for PROV-based provenance traces coming from various sources, that leverages Sankey Diagrams to reflect the flow of information through activities. We briefly discuss the advantages of this approach compared to other provenance visualization tools. PROV-O-Viz has already been used to visualize provenance traces generated by very different applications.
