ekioplot 0.4.0

Breaking changes

• Removed run_palette_lab() and the bundled Shiny app. The Palette Lab now lives in its own repository (https://github.com/viniciusoike/ekioplot-palette-lab) and runs entirely in the browser at https://viniciusoike.github.io/ekioplot-palette-lab/. This drops 8 app-only Suggests (bslib, colorspace, colourpicker, forcats, ggbump, patchwork, shiny, stringr), leaving ekioplot a lean visualization package.

ekioplot 0.3.1

Documentation

• Rewrote README.md to match the current API (the previous version referenced removed font helpers, theme style names, and palette names that no longer exist).

Infrastructure

• Added an R-CMD-check GitHub Actions workflow covering Windows, macOS, and Linux (release, devel, and oldrel).
• Removed stale repository artifacts and scratch files.

ekioplot 0.3.0

Breaking changes

• Complete API overhaul. Palette system, themes, and scales have been redesigned with a cleaner, more consistent interface.

Color system

• Unified palette access through ekio_pal() — all palette types (categorical, small-group, scientific, sequential, diverging) are accessible from a single function.
• Added 8 sequential palettes (blue, teal, gray, orange, purple, red, green, amber) and 3 diverging palettes (blue_orange, blue_red, teal_orange).
• Added curated small-group variants: duo_warm, duo_cool, trio_bold, trio_cool, quad_earth, quad_vivid.
• Added scientific palettes: okabe_ito, viridis, inferno, plasma.
• list_ekio_palettes() now validates the type argument and errors on invalid types.
• ekio_orange now has 10 shades (50-900), matching the other color scales.

Themes

• theme_ekio() rebuilt using ggplot2's modular theme_sub_*() helpers (requires ggplot2 >= 3.5.0).
• Added theme_ekio_map() for choropleth and spatial visualizations.

Scales

• Added continuous scale functions: scale_color_ekio_c() and scale_fill_ekio_c() for sequential and diverging palettes.
• British spelling aliases (scale_colour_ekio_c(), scale_colour_ekio_d()) included.

Recipe functions

• Added high-level chart builders: ekio_histogram(), ekio_lineplot(), ekio_scatterplot(), ekio_barplot(), ekio_areaplot().
• Smart aesthetic detection automatically distinguishes static colors from variable mappings and applies appropriate scales.

Tables

• Added gt_theme_ekio() for professional gt table styling with EKIO branding.
• Fixed gt_theme_ekio() crashing on tables without summary rows or row groups.

Datasets

• Added fuels dataset (global fuel consumption time series).
• Added brazil_agriculture, brazil_agriculture_states, brazil_gdp, and brazil_population datasets.
• Added ips_brasil dataset (Social Progress Index for Brazilian municipalities).

Other

• Removed dplyr dependency.
• Removed scales from Imports (not used directly).
• Removed dead code and obsolete prototype files.
• Added Shiny palette explorer app (inst/shiny-app/).
• Added test coverage for recipe functions and gt theme.
