How would you make a better plot? In the previous two exercises, we looked at the relationship between life expectancy and Internet use. First, we made a scatterplot for all 181 countries in the data set. Then we made one for the subset of 48 European countries. Explain how you would construct a single plot to make a comparison between the European countries and the other countries in the data set. (Optional: Make the plot if you have software that can do what you need.)
