The graph shows the the relationship between the density of the lower layers of Earth’s atmosphere and elevation above Earth’s surface. Since the composition of the lower atmosphere doesn’t vary much, the change in density of Earth’s atmosphere is dependent mostly on how the number of gas molecules in a specific volume changes.
