Use the snapshots.pdf file, together with its hyperlinks to the underlying spreadsheet data. Use a spreadsheet program of your choice to complete the following.
(a) Make a plot of per capita GDP (in dollars) for the years 1950 to 2014 for a country of your choice. Label the x- axis “year” and the y-axis
“per capita GDP.”
(b) Make a plot of per capita GDP relative to the United States (U.S. = 100) for the years 1950 to 2014 that includes the United States and three other countries of your choice, all on the same graph. Be sure to label the lines on the graph in some informative way so that each line can be associated with its country.
