Abstract (in Japanese) (See Japanese page) 
(in English) We extracted companies from Japan's corporate database, specifically those in Tokyo, Kumamoto Prefecture, the Kyushu region, the nationwide manufacturing sector, and the nationwide automotive industry. For each group, we visualized the 12-year trend from 2010 in the following metrics: the relationship between sales revenue, capital, number of workers, and number of companies; the clustering coefficient when representing inter-company transaction relationships as an unweighted undirected graph; the average degree; and the degree distribution.
