We visualize the Wiki revision history based on a History Flow, which is a visualization tool for a time-sequence of snapshots of a document in various stages of its creation. The previous History Flow was judged to be inadequate in that it did not display the relationships between the authors, so prevents users from analyzing the meaning of the revisions of the data. First, this study introduces the Flow Circle, which is a new exploratory data analysis tool devised to solve such problems of History Flow. Second, this tool is used to actually visualize the Wiki revision history regarding gun politics in order to understand and analyze the flow of the revision history and the relationship and conflict structures between the authors based on the results of the MDS analysis.
