Pictographs:

Reason to adopt : Pictographs are a special kind of bar graph in which the bars are replaced by drawings that represent the thing being described. The chief advantage of the pictograph is that it uses drawings to symbolize concretely the quantities you are talking about in your graph. You will find pictographs especially useful where you want to do one or both of the following: • Emphasize the practical consequences of the data represented. • Make your data visually interesting and memorable.
