Comments on "Towards Unambiguous Edge Bundling: Investigating Confluent Drawings for Network Visualization"
Bach et al. [1] recently presented an algorithm for constructing confluent drawings, by leveraging power graph decomposition to generate an auxiliary routing graph. We identify two problems with their method and offer a single solution to solve both. We then recognize a limitation regarding planarity, and help to guide future research by introducing a new classification of 'power-confluent' drawing.
