The values of `hwy` and `displ` are rounded so the points appear on a grid and many points overlap each other.
The underlying values of `hwy` and `displ` are rounded so the points appear on a grid and many points overlap each other.
This problem is known as **overplotting**.
This arrangement makes it hard to see where the mass of the data is.
Are the data points spread equally throughout the graph, or is there one special combination of `hwy` and `displ` that contains 109 values?
