Adding a Touch of glitr: Developing a Package of Themes on Top of ggplot
summary
USAID builds glitr on ggplot2 with extrafont and grDevices, adds a one-line SI_style theme plus nine variants, a scale_fill_SI palette and SI_style_grid, and packages export defaults (size/DPI) and color interpolation; colors are tuned with Adobe Color and vizpalette. Code lives on GitHub, used across a 300-person office and partner missions, cuts repeated hexes and boilerplate, speeds plotting and onboarding, and produces consistent, accessible visuals.
