# Topic C: Picture Graphs

Picture graphs are similar to bar graphs. Picture graphs show comparisons between quantities. A little picture represents a certain amount. Look for the legend to find out that amount. Picture graphs will give fractions of a picture also. For example, if the picture represents 100 things, half a picture would be 50.
