A chart is a way to show data or information visually by using pictures. For example, a chart might use a bar graph to show how tall different family members are. The numbers on the bottom of the chart could tell us how tall each person is, while the bars going up and down help us to compare the heights at a glance. Charts can be used to show lots of different kinds of information, such as how many people like different kinds of food or how much money a person has saved.
