Base-graphics mosaic plot (via graphics::mosaicplot()), matching the
existing base-graphics precedent in this file
(sframe_draw_likert_diverging()) so it renders without ggplot2. An
alternative view of the same crosstab data
sframe_plot_crosstab() renders as a grouped bar. Use whichever reads
better for the table's shape (mosaic scales better to unbalanced group
sizes).
Usage
sframe_draw_mosaic(result, palette = c("web", "print"))
