Fuel Efficiency vs. Weight

Let’s look at how vehicle weight affects miles per gallon (MPG).

library(ggplot2)

ggplot(mtcars, aes(x = wt, y = mpg)) +
  geom_point(aes(color = factor(cyl)), size = 3) +
  geom_smooth(method = "lm", se = FALSE, color = "gray") +
  labs(
    title = "MPG vs Weight",
    x = "Weight (1000 lbs)",
    y = "Miles per Gallon",
    color = "Cylinders"
  ) +
