A graph is a kind of drawing that shows mathematical information, ideas, and relationships. In statistics, examples of graphs used to represent data are bar graphs, picture graphs, circle graphs, line graphs, line plots, and stem-and-leaf plots.

In algebra and geometry, number lines are used to graph ordered pairs, equations, and other mathematical relationships.
