In turn, what do you think is distinctive about graphics for panel data?

If the essence is having several panels over several time periods,
then that is easy in principle but often a mess in practice. -xtline-
is a dedicated command.

Concretely in your case, 40 years is not a problem, but 120 countries
is, beyond showing and trying to make sense of lots of spaghetti
plots. You may need to select countries or think about appropriate
reductions of your data.
