Faceting by year
All of the graphs in this chapter have been visualizing statistics within one year. Now that you're able to use faceting, however, you can create a graph showing all the country-level data from 1952 to 2007, to understand how global statistics have changed over time.

Introduction to the Tidyverse
Exercise instructions
- Create a scatter plot of the
gapminderdata: - Put GDP per capita (
gdpPercap) on the x-axis and life expectancy (lifeExp) on the y-axis, with continent (continent) represented by color and population (pop) represented by size. - Put the x-axis on a log scale
- Facet by the
yearvariable
