A relationship visualization reveals how two or more variables affect each other. You can show relationships through a variety of methods.

The simplest is a line graph showing how one variable rises or falls along the Y axis as it moves through degrees of another variable on the X axis. A scatter plot is useful when the data is not linear, such as representing the height and weight of a population, where there are multiple instances of weight for each height. A bubble chart is a scatter plot using the size of the bubble to represent a third variable.

You can also indicate relationship by graphing two variables on one axis across a third variable on the other axis. Figure 3-4 graphs call center wait times and customer satisfaction scores across time.
