#' Transformed and flipped Cartesian coordinate system
#'
#' `coord_trans_flip` behaves similarly to [ggplot2::coord_trans()] in that it
#' occurs after statistical transformation and will affect the visual appearance
#' of geoms. The main difference is that it also flips the x and y coordinates
#' like [ggplot2::coord_flip()].
