The e_draft helper function is a very simple wrapper aroudn the graphics API and thus a good example of what can be achieved.

cars |>

  e_scatter(dist) |>
  e_draft()

Image

You can add an image for instance.

cars |> 
  e_charts(speed) |>

  e_image_g(
    right = 20,
    top = 20,
    z = -999,
    style = list(
      image = "https://www.r-project.org/logo/Rlogo.png",
      width = 150,
      height = 150,
      opacity = .6
