What geom would you use to draw a line chart? A boxplot? A histogram? An area chart?

Run this code in your head and predict what the output will look like. Then, run the code in R and check your predictions.

ggplot(data = mpg, mapping = aes(x = displ, y = hwy, color = drv)) + geom_point() + geom_smooth(se = FALSE)

What does show.legend = FALSE do? What happens if you remove it? Why do you think I used it earlier in the chapter?

What does the se argument to geom_smooth() do? Will these two graphs look different? Why/why not?

ggplot(data = mpg, mapping = aes(x = displ, y = hwy)) + geom_point() + geom_smooth() ggplot() + geom_point(data = mpg, mapping = aes(x = displ, y = hwy)) + geom_smooth(data = mpg, mapping = aes(x = displ, y = hwy)) Recreate the R code necessary to generate the following graphs.
