Long description

The figure is a line chart with the x axis labelled as ‘time’ and the y axis labelled as ‘demand’. There is a line on the chart (coloured in black) labelled as ‘demand’ that starts low, dips, and then curves upwards towards a peak, falls to a new minimum point, and then rising again. A second line, labelled ‘capacity’, sits entirely above this fluctuating demand curve. This line is straight and horizontal across the entire graph.
