In this paper, we propose an extension to the standard Chord diagram to show data elements from two heterogeneous data sources into one single diagram. The main Chord diagram is used for showing data elements and the relations between them from one data source, while we use an outer layer to show data elements from the second data source. The relationships between data elements from both data sources are shown through visual cues. The proposed solution uses space efficiently compared to using multiple diagrams in the scenarios of two heterogeneous data sources.Attribution 4.0 International LicenseCCS Concepts: Human-centered computing --> Information visualization; Graphical user interfacesHuman centered computingInformation visualizationGraphical user interfaces10.2312/evp.20221137127-1293 pages
