One does not,
and that (whole area) was the main reason I mentioned "violin
plots" which do show features such as bimodality:

There's a simple violin plot in the (recommended and hence
always available) package "lattice"

library(lattice)
example(panel.vioplot)

but for the sake of bimodality {and the version of violin plot
that was in the 1998 Am.Stat. paper}

install.packages("vioplot") # if needed
example(vioplot)

Both of these examples use the basic boxplot but *add* to it, so
you can, e.g., clearly discern bimodality.
