You should have included the data here, why put an image if you can actually upload the data?

Why is it insightful that California had 2000 deaths a month in May? Same for the other ones.... Better insights would be: in May 2020 California had lost 0.79% of its population when the rest of the Country only lost 0.2%. Identifying outliers Each one of these tasks should be compared against the standard for the country

For your 5 idioms I was expecting different tasks, and insights. These seem like very subtle iterations over your main idea...

I just noticed that you combined the HOW for the map and the interactive timeline.... This is very confusing, you shouldn't do that...

As with most Choropleth maps they tend to show a population graph. Yes, we know Texas and California have many people. Also, with Choropleths you get different area for your marks, so smaller geographical states as New York are poorly represented. You should try using circles as marks and compute measures that allow you to compare between states

e.g. At least normalize by state (%)
