Reducing Visual Complexity in Software Maps using Importance-based Aggregation of Nodes

in Proceedings of the 8th International Conference on Information Visualization Theory and Applications . 2017 .

Depicting massive software system data using software maps can result in visual clutter and increased cognitive load. This paper introduces an adaptive level-of-detail (LoD) technique that uses scoring for interactive aggregation on a per-node basis. The scoring approximates importance by degree-of-interest measures as well as screen and user-interaction scores. The technique adheres to established aggregation guidelines and was evaluated by means of two user studies. The first user study investigates task completion time in visual search. The second evaluates the readability of the presented nesting level contouring for aggregates. With the adap- tive LoD technique software maps allow for multi-resolution depictions of software system information. It facilitates efficient identification of important nodes and allows for additional annotation. © The Authors 2017. This is the authors' version of the work. It is posted here for your personal use.
