Abstract
In professional soccer games, ball touch-based play data (event data) and tracking data on player movements are obtained. It is difficult for coaches, players and fans to utilize the data in numerical form, so it is necessary to visualize the data in a format that is easy for non-specialists to handle. In this paper, we present examples of initiatives to visualize soccer data in Japan and abroad. In Japan, indicators have been developed to evaluate plays that lead to the creation of shooting chances and individual player characteristics using data from the J-League. On the other hand, in Europe and the United States, data scientists and soccer analysts from top clubs are visualizing the tactical value of spaces and conducting educational activities on data analysis in collaboration with universities. The efforts of data experts to visualize soccer data have significant value in ensuring that this data is used more effectively.
