Fig. 6

The TransCodes adapted for New York City, San Francisco, Toronto, London, Berlin, and Tokyo during different periods. 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 uncovered or 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)
