COVID-19 Geographical Animation Generators
These Mathematica files will read COVID-19 time series data from Johns Hopkins University Center for Systems Science and Engineering's GitHub page and generate an mp4 movie file that animates how the numbers of positive cases developed over space and time.
Examples can be seen in the following:

In the visualization, the size of each disc represents the number of daily new positive cases (scaled). The color of the disc is determined by (# of daily new cases) / (max # of daily new cases observed up to that point), which ranges from 0 (end of epidemic; blue) to 1 (growing or peak of epidemic; red).
Data was smoothed using seven-day moving averages.
