Point-based tree representation: A new approach for large hierarchies
Hans‐Jörg Schulz, Steffen Hadlak, Heidrun Schumann · 2009
Space-filling layout techniques for tree representations are frequently used when the available screen space is small or the data set is large. In this paper, we propose a new approach to space-filling tree representations, which uses mechanisms from the point-based rendering paradigm. Additionally, helpful interaction techniques that tie in with our layout are presented. We will relate our new technique to established space-filling techniques along the lines of a newly developed classification and also evaluate it numerically using the measures of theink-paper-ratioandoverplotted%.
