Directed graph visualizing apparatus and directed graph visualizing method

摘要

PROBLEM TO BE SOLVED: To improve visibility of a valid graph.SOLUTION: A device which visualizes a directed graph includes: a sequence pattern extraction part which extracts a plurality of patterns in which a sequence of nodes contained in a path included in the directed graph are arranged; a similarity calculating part which calculates similarity of each position by comparing the nodes at the same position from a head of each pattern; a display area calculation part which allocates a display area to each position so that the display area is wider as the similarity is lower; and an element arrangement part which arranges the node on the allocated display area.
