Changes in version 0.1.0 (2026-03-16)                  

  - Initial CRAN release.

New features

  - geom_marimekko() — formula-based mosaic/marimekko plots as a ggplot2
    layer. One-sided formulas (~ a | b) encode both variable hierarchy
    and split direction. | alternates between horizontal and vertical
    splits; + groups variables in the same direction.
  - geom_marimekko_text() and geom_marimekko_label() — place text or
    label annotations at tile centres, with access to computed variables
    via after_stat().
  - fortify_marimekko() — extract tile rectangles as a data frame
    without plotting.
  - theme_marimekko() — a minimal theme designed for mosaic plots.
  - marimekko_pal — a categorical colour palette.

Computed variables

  - .proportion — conditional proportion within the parent tile.
  - .marginal — joint proportion relative to the whole dataset.
  - .residuals — Pearson residuals measuring departure from
    independence.

Other

  - show_percentages = TRUE appends marginal percentages to x-axis
    labels.
  - Independent gap control via gap_x and gap_y.
  - Formulas support arbitrary R expressions (e.g., ~ factor(cyl) |
    cut(mpg, 3)).
  - Compatible with facet_wrap(), facet_grid(), and plotly::ggplotly().
