There are many different types of graphs, but some of the most common are bar graphs, line graphs, and pie charts.
Bar graphs are used to compare different values, usually data that is measured over time. For example, a bar graph could be used to show how much rain fell in different months, or how many people attended a concert each day.
Line graphs are similar to bar graphs, but they show how values change over time. For example, a line graph could be used to show how the stock market has fluctuated over the past year.
Pie charts are used to show how much of something is divided into different parts. For example, a pie chart could be used to show how a company's expenses are divided between different department.
