On August 8, 2023, I gave an oral presentation at the 51st Symposium on the Visualization Society of Japan (Grand Park Otaru). The title of the presentation was “Visual Analytics of Co-occurrence Relationships among Mantras in Ancient Indian Literature,” and I was able to exchange opinions with a variety of researchers. In addition, I organized and chaired the organized session OS10 “Visual Data Science” at the symposium, and there was a lively question-and-answer session. This research was supported by Grant-in-Aid for Scientific Research 21KK0004 International Research Collaboration Enhancement (B).
