Weekly Post-Session Challenge

This week’s challenge is to make a lollipop chart instead of the bar chart. You need two geoms: geom_point() and geom_segment(). Points give you the yummy candy, and segments are the sticks. Google “ggplot lollipop chart” to get started and post your questions and progress to Piazza.
