Interaction Techniques for Chord Diagrams

Chord diagrams are a popular high-dimensional method for showing connections between nodes, however they have scalability limitations and lack advanced methods for interaction and multivariate links. In this paper we introduce a novel interaction and layout method for improving the scalability of chord diagrams, explore sketch-based methods for showing multiple links and direction, and introduce a sketch-based brushing technique for filtering. We demonstrate the interaction techniques on a real-world call-center dataset and report feedback from domain experts in the call center industry.
