Through 31 March 2020, the United States has tested over 1.1 million Americans for COVID-19 infections in all 50 states and the territories of Puerto Rico and the District of Columbia. The known results of that testing, including the number of positive, negative and pending test results for the SARS-CoV-2 coronavirus, the number of deaths, and also the reported cases severe enough to require hospitalization, are visualized below in the tower chart showing the daily progression of COVID-19 infections in the U.S. since 10 March 2020.
In the following chart, we've combined the skyline tower charts illustrating the daily progression of positive COVID-19 infections, hospitalizations, and deaths for each of the 50 states and the territories of Puerto Rico and the District of Columbia, ranking each from worst to best as you read from left to right, top to bottom. All charts are presented covering the same period of time from 10 March 2020 through 31 March 2020 and use the same scale, with the width of the charts representing 0.5% of the state or territory's population, making is easy to quickly visualize in which states the coronavirus infections are concentrated and are spreading the fastest.
It appears from the available data that a number of states are not reporting their number of coronavirus-related hospitalizations, with New Jersey, Michigan, the District of Columbia, and Illinois standing out in that category among the top 10 states ranked by share of their population having been infected.
We're also well past the point where it is worthwhile to track the daily progression of COVID-19 in states whose governors have mandated business closures or stay-at-home orders for their residents. Also as of 31 March 2020, three out of four Americans are affected by these restrictions, which have spread far faster than the coronavirus.

Update 31 March 2020: Thank you for scrolling all the way down to the bottom of this article! If you're viewing the original version of this article, here's where we will periodically post updates to the national tower chart presented above, or will link to newer posts in the series where you can find updates for all the charts.
Update 29 April 2020: Here's the latest update to the national tower chart showing the cumulative totals:
The biggest changes in the daily numbers are coming from the Top 10 states. New York continues to have the largest number of confirmed cases, accounting for nearly a third of all confirmed cases in the U.S. and nearly two-fifths of reported deaths, with New York City and the surrounding counties that make up its greater metropolitan area having the largest share (counties in New Jersey adjacent to New York City have been similarly hard hit, with that state ranking second in the nation). Excluding the extremely high concentration of cases in this region, data from the rest of the U.S. is more similar to that being reported by Germany.
