The Best Coronavirus Graph

Best because: Deaths, unfortunately, are more reliable than number of cases, which depends on the amount of testing. If a country has only done 100,000 tests, it will never show many more than 100,000 cases (though some cases are recognized by symptoms). It shows new cases, not the total number which may be huge and is in the past.  It shows numbers divided by country's population, the only reasonable ways to compare countries with populations varying from 1.3 billion to 330 million to 60 million. It is smoothed (shows rolling 7 day average). Without smoothing there is so much random variation it is hard to see any trend.  Comments on Graphs: Most countries have a fast increase followed by a long slow decline.  The United States's decline is especially slow.  Hover over country name to see just that countries graph.  Click on graph title to go to orignal website, where you can add and remove countries and see lots of other graphs.  Not smoothed.
