The plot shows a negative relationship between engine size (`displ`) and fuel efficiency (`hwy`).
In other words, cars with big engines use more fuel.
In other words, cars with smaller engine sizes have higher fuel efficiency and, in general, as engine size increases, fuel efficiency decreases.
Does this confirm or refute your hypothesis about fuel efficiency and engine size?
With ggplot2, you begin a plot with the function `ggplot()`.
