The plot shows the correlation of two of the main car variables that correlate pretty well with fuel consumption.

The data is from the R dataset “mtcars” (a dataset of 32 automobiles from 1973-74).

The plot features an interactive label that allows the easy identification of the car.

The two variables or dependant variables are:

• wt Weight (1000 lbs)
• hp Gross horsepower

and the independent variable is:

• mpg Miles/(US) gallon
