#' Tufte Maximal Data, Minimal Ink Theme
#'
#' Theme based on Chapter 6 'Data-Ink Maximization and Graphical
#' Design' of Edward Tufte *The Visual Display of Quantitative
#' Information*. No border, no axis lines, no grids. This theme works
#' best in combination with \code{\link{geom_rug}()} or
#' \code{\link{geom_rangeframe}()}.
#'
#' @note
#' The default font family is set to 'serif' as he uses serif fonts
#' for labels in 'The Visual Display of Quantitative Information'.
#' The serif font used by Tufte in his books is a variant of Bembo,
#' while the sans serif font is Gill Sans. If these fonts are
#' installed on your system, then you can use them with the package
#' \bold{extrafont}.
#'
#' @inheritParams ggplot2::theme_grey
#' @param ticks \code{logical} Show axis ticks?
#'
#' @references Tufte, Edward R. (2001) The Visual Display of
#' Quantitative Information, Chapter 6.
