Creating a Basic Brick Plot

Let’s start by creating a simple brick plot using the built-in ‘mpg’ dataset. We will use the ‘class’ and ‘drv’ variables to show the distribution of cars based on their numbers.

# basic usage
mpg |>
  count(class, drv) |>
  ggplot() +
  geom_brick(aes(class, n, fill = drv)) +
mpg |>
count(class, drv) |>
gplot() +geom_waffle(aes(class, n, fill = drv)) +
mpg |> 
count(class, drv) |>
ggplot() +
geom_waffle0(aes(class, n, fill = drv)) +
coord_flip() +
theme(aspect.ratio = 1.8)
