ggtwotone: Dual-Tone and Contrast-Aware 'ggplot2' Geoms
Provides dual-stroke and contrast-aware extensions to
'ggplot2', designed for improved visibility and accessibility in
complex visualizations. Includes geoms for dual-stroke segments,
regression lines, curved annotations, function plots, paths, and
adaptive text. Also includes utility functions for computing
contrast-aware color pairs and perceptually distinct highlight
palettes using Web Content Accessibility Guidelines (WCAG)-based
contrast logic.
