Scatterplot

Figure 5-16. Scatterplot. Two continuous variables. Additional continuous, ordinal, or categorical variables can be added for size, color, and shape. This shows the relation between curb weight and MPG for five different styles of car.

Description

A scatterplot places data points on perpendicular axes. The two major axes are used to lay out the points spatially; additional attributes can be used for color, size, or shape.

Scatterplots encourage the user to look at groupings in space. They can identify outliers or groups, such as the points that are in each cluster or the points that are along a main trendline. If the points are colored with an additional categorical variable, then they can address questions about whether different categories behave differently from each other.
