The data is from the Johns Hopkins University(JHU) (see https://github.com/CSSEGISandData/COVID-19). We have normalized the number of daily confirmed cases by dividing by the populations for the various countries. In the charts below trajectories are often labeled by the Top Level Domain (TLD, see https://en.wikipedia.org/wiki/Top-level_domain), or state abbreviation (see https://en.wikipedia.org/wiki/List_of_U.S._state_and_territory_abbreviations) or just the name of the country or states. The data includes about 160 countries with a population of ~ 7.4Billion people.

Observations
There are notable differences in the numbers of confirmed Covid-19 cases per million population between the various regions of the world. The lowest number of cases are in the Asia east and Australasia sub-region followed by the Asia south east sub-region. The highest numbers of cases are in Europe west, Europe central and Europe south east. The differences in cumulated confirmed cases per million population between these two groups are well over a factor of 10
When one takes each US state separately rather than the US as a whole, the maximum Y-scale (confirmed cases daily per million population) goes from 800 to 2000. This is much closer to the maximum Y-scale for the 36 European countries. Also note the differences in the US state peaks for the first wave (led by New York and other eastern US states), second wave (led by Florida and Arizona), and the third wave (led by North Dakota, South Dakota, Iowa, Wyoming).
It is interesting that the most physically isolated state Hawaii (HI), and physically isolated countries such as Fiji (FJ), New Zealand (NZ), Papua New Guinea (PG), Solomon Islands (SB), Ireland (IE), Bermuda (BM) in America north, and the Caribbean islands, tend to have lower cases per capita. A notable exception is Iceland (IS in Europe north)
