The mutated dataset is preloaded as gapminder_Africa_2010.
As in the previous exercise, make a scatter plot of infant_mortality versus dollars_per_day for countries in the African continent.
As in the previous exercise, use color to denote the different regions of Africa.
Transform the x axis to be in the log (base 2) scale.
