Results of temporal clustering of the case dynamics and the inferred TransCode for each period in Tokyo. a The sequence is partitioned into four periods, demonstrating different temporal patterns. The last segment is called the Olympic period because the Tokyo Summer Olympics were held during this period (July 23 to August 8, 2021), representing the main cause of this outbreak wave. b Visualization of the inferred TransCodes for four periods in Tokyo. In each subfigure, the map shows the number of cumulative confirmed cases in each district during the corresponding period (darker colors indicate higher case numbers); the transmission network represents the inferred TransCode. The network nodes correspond to the districts, and the directed network edges show transmission from one district to another (darker edge colors indicate higher transmission intensities)
