Demand Is Not Hypothetical

Virtually all economics textbooks treat Demand hypothetically.  They strike a line to show how prices would theoretically fall as quantities increase.

In the real world, market Demand manifests itself as a series of points, with quantities (here, of bomber models) on the horizontal axis, and prices (as bomber prices) on the vertical axis, as shown below.  Note the limiting values for this market, shown in open circles.  Collectively, what do these circles represent?
