Fig. 2: The spatial spreading pattern of COVID-19 in Wuhan, Beijing, and Urumqi.
From: A general urban spreading pattern of COVID-19 and its underlying mechanism
a–c A visualization of the number of confirmed cases in discretized grids in Wuhan, Beijing, and Urumqi, respectively. d–f The human mobility distribution (dots) as a function of traveling distance and the fitted models (lines) for Wuhan, Beijing, and Urumqi, respectively. g–i The spatial distributions (dots) as a function of distance from the overall spreading centroid and the fitted regression lines for these distributions.
