Properties of Euler Diagrams and Graphs in Combination

Euler diagrams and graphs are used as visualisations individually in a large variety of application areas such as network analysis, medicine and engineering. Existing methods which combine both Euler diagrams and graphs such as Bubble Sets and Euler View provide somewhat limited results with suboptimal layout. In particular, they do not produce diagrams that are known to be most effective for performing user-driven tasks. That said, our knowledge is rather limited about what constitutes an effective layout for Euler diagrams and graphs in combination. Our ultimate aim is to automatically visualise large networks in an effective manner. To produce effective layouts, we need to identify properties that may correlate with effective layouts of Euler diagrams combined with graphs. Such properties are considered in this paper. In future, empirical studies will be conducted to inform and validate the combined properties.
