We draw a demand curve to show the relationship between the price of the good and the quantity that consumers are willing to buy. For example, suppose people are willing to buy 20 pounds of strawberries at a price of $2, but are willing to buy 30 pounds if the price falls to $1.
You can show the demand curve shift leftward or rightward with a graph. Changes in quantity demanded mean demand curve does not shift but rather move along the curve as it is caused by changes in price of the goods itself. hope this helps! sportandstock.blogspot.com.
