All values represent the maximum value per month of the 7-day moving average of daily deaths per country. No scaling per population, just plain daily deaths, from the official announcements of each country.
The colouring provide a quick and easy way to visually understand the trend.
The last column is the percentage of the latest value (7-d avg in November) over the maximum over the entire period Feb-Nov. So, the values of 100% mean that the maximum is in November 2020.
