I made this visualization using R 3.6.1 and ggplot with COVID-19 case count data from the New York Times (nytimes/covid-19-data). States are sorted from top to bottom by the date that the weekly average of daily new cases peaked. These growth rates were normalized across the states for the sake of the visualization. Curves are colored by major US region as defined by the US Census Bureau. Along the right side is the date that the growth rate peaked.
If you have any critiques/suggestions/questions please let me know!
