If we want to add a point layer, we simply add geom_points() (this is an example of a geometric object).
Graph the data, learn what you can, and then regraph the data to answer the questions that arise from your previous graphic.
On the horizontal axis, we see the year, and the vertical axis represents the percentage of children with a particular name.
They recently had an annual bird count where, on a particular day, they record the number of birds bound of various species.
