For each country a stack of three graphs is presented. In every graph the abscissa is the number of days with respect to the beginning of 2020: day 1 is 1 January 2020.

In every upper graph the ordinate is the number of daily deaths multiplied by 100000 and divided by the population of the country.

In every upper graph data are shown for at least one year prior to 2020 and the data for 2020 and 2021 are shown as a solid black line.
Data for various years are indicated thus:


In every middle graph the ordinate is the cumulative number of excess deaths multiplied by 100000 and divided by the population of the country. Thus for a country having a population comprising N people, an ordinate of 100 means that by the day in question there were N/1000 deaths in excess of the number of deaths expected.

In every lower graph the ordinate is the so-called "stringency index", a measure of non-pharmaceutical interventions in place on the day in question. Please refer to the data publishers' discussion of the significance of this parameter.
