Abstract
This paper presents a visualization technique of hierarchical data which each leaf and non-leaf node has multi parameters. The technique determines the dominant two parameters from the multi parameters, by applying response surface technique. By assigning the two parameters to horizontal and vertical axes of display spaces, the technique represents the dependency among the dominant parameters of hierarchical data. The technique applies Heiankyo View, a visualization technique for large-scale hierarchical data. The paper introduces some visualization results proofing the effectiveness of the presented technique, and a scientific application that the presented technique is to be effectively used.
