Market equilibrium
Drag the demand or supply curve sideways to shift it, and drag the dashed price line off the crossing point to see a surplus or shortage appear — then watch why price gets pushed back.

Above the crossing point, sellers offer more than buyers want — a surplus pushes price down. Below it, buyers want more than sellers offer — a shortage pulls price up. Drag the curves to shift demand or supply and watch the equilibrium move.
