I'll provide a more general overview below.

A supply and demand diagram is an illustration of the quantities demanded and supplied at varying price points. The supply curve is upward sloping, illustrating the law of supply, and vice versa for the demand curve.

The point at which the supply and demand curves intersect is the equilibrium point, i.e. where the quantities demanded and supplied are equal. The price at this point is the equilibrium price, the quantity at this point is the equilibrium quantity.

Changes in price leads to a movement along the curves, which means a change in the quantity demanded or supplied. Changes in factors other than price lead to a shift of the curves. Consequently, a shift leads to a change to the equilibrium point. The effect of a shift in the curves will hence be illustrated by the change in equilibrium price and quantity.

That's an excellent, accurate summary - concise yet comprehensive.
