I have some doubts about the representation of the COVID-19 epidemic by the John Hopkins platform.
In the most prominent map, they want show numbers of cases linked to a geographic position in a map. They represent this with a big red circle, varying in size for the number of cases. I find this confusing, since it appears that the whole area is infected or were hit by a atomic virus bomb and places with a couple of cases are almost invisible. But what other options are there to visualize where and how many cases?
As a side dish, they show 3 plots of actual, logarithmic, and daily increase. Is that a reasonable way of representing a growing epidemic? This question might slip too much in the opinion based terrain, but I'd like to know what are standards ways of representing this, and why these three are relevant.
What could be a plot for showing how fast and how far the cases are spreading or possible outbreaks?
