Query: Is the epidemic spread related to GDP? Visualizing the distribution of
  COVID-19 in Chinese Mainland   In December 2019, COVID-19 were detected in Wuhan City, Hubei Province of
China. SARS-CoV-2 rapidly spread to the whole Chinese mainland with the people
during the Chinese Spring Festival Travel Rush. As of 19 February 2020, 74576
confirmed cases of COVID-19 had been reported in Chinese Mainland. What kind of
cities have more confirmed cases, and is there any relationship between GDP and
confirmed cases? In this study, we explored the relationship between the
confirmed cases of COVID-19 and GDP at the prefectural-level, found a positive
correlation between them. This finding warns high GDP areas should pay more
prevention and control efforts when an epidemic outbreak, as they have greater
risks than other areas nearby.
