Abstract
Recently, it is crucial to appropriately and compactly represent huge information in various situations. The technology to improve visual recognition is well studied and called "Information Visualization". We consider visualization of a "graph" used for representing relations of items. When a graph is large and complex, the vertices and edges must be laid out adequately; otherwise, the graph becomes hard to read. In this paper, we propose a graph layout method by using curved edges based on a leaf-spring model. Our method is effective to satisfy three aesthetic criteria : moderate distribution of vertices, higher angular resolution, and less curvature of curved edges.
