Graphics are instruments for reasoning about quantitative information.
Often the most effective way to describe, explain, and summarize a set of numbers is to look at a picture of the numbers. Well-designed data graphics are the simplest and most powerful method of analyzing and communicating numerical information. It is simple to make and read, and most useful for plotting continious data to show trends and relationships. Although a bar chart may better show dramatic comparisons of amount, the ability to use several curves on the same line graph makes the line graph superior. Bar charts represent values or amounts by bars of scaled lengths.
