Appropriate mappings

Incorrect aesthetic mapping causes confusion or misleads the audience.

Typically, the dependent variable is mapped onto the the y-axis and the independent variable is mapped onto the x-axis.

In the ToothGrowth data set, we have three variables:

Variable	Description
`len`	Tooth length
`supp`	Supplement type (VC or OJ)
`dose`	Dose in milligrams/day

From the six possible ways to map three variables, one solution is shown in the viewer. Which of the remaining five would actually be a better solution?

Possible Answers

x = supp, y = len, color = dose
x = dose, y = supp, color = len
x = len, y = dose, color = supp
x = len, y = supp, color = dose
x = supp, y = dose, color = len
