Visualizing several variables at once with facets
In the visualization you just created, the y-axis extended to fit avg_salary
, which was in the thousands. That meant that you couldn't see the bars for the other two variables you were trying to study. Here you'll use faceting so that each variable plot has its own y-axis.
