Example of a Mosaic Plot
The proportions on the x-axis represent the number of observations for each level of the X variable, which is country.
The proportions on the y-axis at right represent the overall proportions of Small, Medium, and Large cars for the combined levels (American, European, and Japanese).
The scale of the y-axis at left shows the response probability, with the whole axis being a probability of one (representing the total sample).
