Solution Summary
This solution defines five types of graphs that are commonly used, namely: pictographs, line graphs, circle or pie graphs, histograms and line plots, and stem-and-leaf-plots. The solution also provides an example for each type of graph, which will help the student decide when to use each type of graph in future.

The cases that correspond with the graph types are:
1) Pictographs- visualization of the numerical value of the corresponding data. For example, using an image of a person to represent one million people shown next to the name of each state in the US to represent the population of that state (i.e., three people would symbolize that the population of the state is three million)
2) Line plot- shows the number of times a particular value occurs. For example, if the scores on a test are ...
