Evaluation of Sketchiness as a Visual Variable for 2.5D Treemaps

Limberger, Daniel; Fiedler, Carolin; Hahn, Sebastian; Trapp, Matthias; Döllner, Jürgen in Proceedings of the 20th International Conference of Information Visualization (IV'16) 2016 .

Interactive 2.5D treemaps serve as an effective tool for the visualization of attributed hierarchies, enabling exploration of non-spatial, multi-variate, hierarchical data. In this paper the suitability of sketchiness as a visual variable, e.g., for uncertainty, is evaluated. Therefore, a design space for sketchy rendering in 2.5D and integration details for real-time applications are presented. The results of three user studies indicate, that sketchiness is a promising candidate for a visual variable that can be used independently and in addition to others, e.g., color and height. © The Authors 2016.
