Line graphs compare two variables. Each variable is plotted along an axis . A line graph has a vertical axis and a horizontal axis. So, for example, if you wanted to graph the height of a ball after you have thrown it, you could put time along the horizontal, or x-axis, and height along the vertical, or y-axis.

A Bar Graph (also called Bar Chart) is a graphical display of data using bars of different heights.

Circle graphs, also called pie charts are used to show how the whole of something is divided into parts.
