If you're talking about that first graph on the page, I think that it is not very helpful. Comparing total number of deaths can be misleading, especially for small countries like Sweden. If my state had a Coronavirus death rate as high as Sweden's 15,000 more people would be dead. Still not "millions", but it wouldn't be an ideal outcome.

Sweden is pitched as as some kind of example of handling the pandemic correctly, when their numbers[1] don't look good at all. From their numbers[2] 44% of people diagnosed ends up dead, implying they are way under tested or they have ridiculously deadly strain (I think it is the former). Because of that the most reliable indicator from them is number of deaths.

Now compare number of deaths with countries that reacted quickly, for example: South Korea, Taiwan, Australia, New Zealand, Norway and others.
