The map seems to be loading correctly on my end (tested in Safari, Chrome, Firefox). Data appears for Wyoming and Alaska. Either there is new data (a grim thought) or some changes were made. However, I don't see data for New Hampshire.
My guess is that there is missing data for states in a given time period and the mapping function doesn't know how to render the state. A default condition is likely needed before the data is added to the map. Might be worth adding some logic to check to see if there data for all 50 states for all time periods. If there isn't, then add NA or 0.
I noticed that the main file is executing the web scrapping script. It might be worth isolating the scrapping and cleaning process from the app as there might be some unforeseen issues down the line when the source is updated or changed. The scrapping script could be run on demand (i.e., in the app trigged by a button) or using a scheduler (i.e., daily, weekly, etc.).
Hope that helps!
