Suppose you are writing a report that compares the average monthly temperatures over the course of one year between two Sunbelt states. Which visual aid would most clearly support your purpose?

Line graph

Answer: A graph or chart.

A chart (also known as a graph) that contains information about the two states' temperatures would be the most useful visual aid in this case.

A chart is a representation of data in which the information is shown through symbols such as bars, lines or slices of a pie. It is used to organize numerical data and to make it easier for people to understand large quantities of data.
