ggplot2 scale functions and a custom theme derived from the Benvi visual identity of QuintoAndar Group (discontinued in 2024). Qualitative, sequential, and diverging palettes with both discrete and continuous scale variants. Includes Poppins font support and high-level chart helpers.
ekioplot
ggplot2 implementation of EKIO's visual identity. Professional themes, curated color palettes, and scale functions for ggplot2 and gt tables. Smart font detection with safe fallbacks and high-level recipe functions for common chart types.
stratr
Companion to {rppi} that builds geographic strata for a property price index using the 2010 Brazilian Census weighting area definitions. Addresses known inconsistencies in the original weighting structure.
