Summary

Covid death tall in Poland versus time by Worldindata [1], black curve, and the three approximations:

\( f(t)= c\, t^3 \)

where \( t\) is time measured in years (1 year=265.25 days)
and values of \( c \) are
30000,
sqrt(3)*10000,
10000.

Generator

Data should be loaded from Worldindata <ref name="o">.

The input table can be generated with command

grep Poland ../owid-covid-data.csv |cut -d, -f 3,4,8,9 > Poland2.txt

Then, the picture can be generated with code below
