The results of three different configurations of the popular Tree Colors algorithm for generating hierarchical color maps. The configurations produce color maps with different characteristics that are suitable for different analysis scenarios. Within this paper, we investigate the impact of six different design rules on hierarchical color map design in different analysis scenarios, to be able to decide which configuration suits our scenarios best.

Abstract

To improve the perception of hierarchical structures in data sets, several color map generation algorithms have been proposed to take this structure into account. But the design of hierarchical color maps elicits different requirements to those of color maps for tabular data. Within this paper, we make an initial effort to put design rules from the color map literature into the context of hierarchical color maps. We investigate the impact of several design decisions and provide recommendations for various analysis scenarios. Thus, we lay the foundation for objective quality criteria to evaluate hierarchical color maps.
