Exercise

Visualizing population

A histogram is useful for examining the distribution of a numeric variable. In this exercise, you'll create a histogram showing the distribution of country populations in the year 1952.

Note: geom_histogram() will output a warning that you should pick a better binwidth. Feel free to ignore this here – you won't be tested on its value. If you do decide to set a binwidth, note that choosing values below 100 million makes ggplot2 perform a lot of computation which can cause the session time out.
