Do you want to sum the total deaths for each of the countries and then plot countries vs. total deaths?

This is a CSV file. What do you call "variables"? Did you import the file already? If so, to which kind of variable? How should the graph look like? 75847 rows are too many to be processed by a human, but for Matlab this is not huge.

@Jan yes the graph should look like number of lines represent the relationship of countries and corresponding accumulated cases and deaths

t=readtable('owid-covid-data_2020-21.csv');
u=unique(t.Location);
s=zeros(1,length(u));
for k=1:length(u)
s(k)=sum(t.TotalDeaths(ismember(t.Location,u(k))));
end
bar(1:length(u),s)
