A "demand curve" is a graph that shows how prices affect consumer demand.
Demand curves demonstrate the graphical relationship between consumer demand (the amount requested for a given time frame) and price (cost of a good or service). In an ordinary representation, the cost will show up on the left vertical axis, the quantity demanded is shown up on the horizontal axis. When there are changes in the non-price factors, we will notice shifts in demand curves.
