displaying columns side by side for a variable in R

Question

How can I show the three values of "disp" for a particular cylinder? Only one column is getting displayed. I am expecting three columns for each cylinder. Any suggestions?

library(ggplot2)
mtcars %>% arrange(desc(disp)) %>% group_by(cyl) %>% slice_head(n = 3) %>% 
  ggplot(aes(cyl, disp)) + geom_col() +facet_wrap(. ~ cyl)

Use Position_dodge or Position_dodge2

mtcars |> arrange(desc(disp)) |> group_by(cyl) |> slice_head(n = 3) |> 
  ggplot(aes(cyl, disp)) + geom_col(aes(fill = disp), position = position_dodge2())

Then you can fill in the bars with whatever variable.
