Effective visualization of hierarchical graphs with the cityscape metaphor
Can Keskin, Volker Vogelmann · 1997
In this paper, we describe an implementation of the cityscape metaphor to visualize trees.The cityscape metaphor is a generallzotion of barcharts in 3D.Our approach serves for better exploitation of human perception capabilities.To achieve this we employ effective visual cues like node position nnd size.We determine node positions in terms of perccptual organization.Further we determine node sizes for providing redundant hierarchical information.Redundancy aides in better understanding the tree structure.Finally, we point out some of the advantages of this approach to other spntial metaphors such as cone trees.
