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.
Best Answer: For a particular good, the market demand curve is the result of aggregation (summation) of all the individual demands for that very good. Graphically you may think of it in the following way: assume you have an individual demand curve with quantity on X axis and price on Y axis. By aggregation I mean simply summation of all the quantities demanded over X axis, i.e. for any price you eventually get the total quantity that individuals are willing to buy.
