The previous fix applied the plot's background to the logo grob
directly, which made it opaque and covered caption/axis text that
overlaps into the logo area via negative margins.
Instead, wrap the entire arrangeGrob composition in a grobTree with
a background rectGrob behind it. This fills transparent areas (logo
strip, padding gaps) with the plot's background color while keeping
the logo grob itself transparent so overlapping text remains visible.
The logo grob uses theme_void() (transparent background), so when
arrangeGrob() composites it with a dark-themed plot, the logo strip
falls back to the device default (white). Extract the plot's
plot.background fill and apply it to the logo grob before compositing.
Fixes the issue where theme_civilytics_dark(font_size = 16) piped to
civilytics_logo(variant = "dark") would show a light background in
the logo/caption area.
Supports "bottom-right" (default), "bottom-left", "top-right", and
"top-left". The position controls both horizontal alignment of the logo
grob and whether it is placed above or below the plot.

- Change rel_large default from 16/14 to 20/14 (~1.43x) to match the
Civilytics editorial design system. Subtitle now renders at 1.0x base
instead of 0.86x.
- Switch axis.text to rel() sizing so all text elements cascade from the
root font_size, enabling uniform scaling.
- Add font_scale parameter (default 1.1) to civilytics_logo(),
add_logo(), and add_logo_ga() — inflates text by ~10% before
arrangeGrob composition to compensate for viewport shrinkage.
- Ship SVG logo variants (mark, wordmark, pulse) in inst/img/ for
Quarto/HTML templates.
- Add "Maintaining brand assets" section to README documenting inst/img/
file inventory and update workflow.
- Document full font size hierarchy in theme_civilytics() roxygen.
R's |> has higher precedence than +, so parentheses ARE required
around the ggplot chain before piping to civilytics_logo():
(ggplot(df, aes(x, y)) + geom_point() + theme_civilytics()) |>
civilytics_logo()
Updated docs, examples, and pipe test accordingly.
- Replace old civilytics_logo.png/white.png/jpg/pdf with new rebrand
assets: civilytics-wordmark.png, civilytics-wordmark-reverse.png,
civilytics-mark.png, civilytics-mark-reverse.png (all transparent bg)
- make_logo_grob() now accepts type = c("wordmark", "mark") alongside
variant = c("light", "dark") for 4 combinations
- New civilytics_logo() pipe-friendly convenience function:
ggplot(df, aes(x, y)) + geom_point() + theme_civilytics() |>
civilytics_logo()
R's |> has lower precedence than +, so the full ggplot chain pipes
through without parentheses
- Remove old icon/favicon assets no longer used
- Wrap showtext-dependent examples in \dontrun{} to prevent R CMD check
failures in headless PostScript environments
- R/colors.R: civilytics_colors named vector (from --cv-* CSS vars on
civilytics.com), three palettes (main/sequential/diverging),
scale_color_civilytics() and scale_fill_civilytics() for ggplot2
- R/fonts.R: auto-loads Inter + Libre Franklin from Google Fonts via
showtext in .onLoad(); exports civilytics_load_fonts() for manual retry
- R/theme.R: wires ggplot2 4.0 ink/paper/accent params into theme_grey()
base, adds title_family + strip_color params; new theme_civilytics_dark()
using navy_dark background and warm off-white text
- R/logo.R: make_logo_grob(variant) accepts "light"/"dark" to select the
white logo for dark-background compositions
- DESCRIPTION: adds showtext, sysfonts; pins ggplot2 >= 4.0.0
- tests/testthat/test_theme.R: full test suite for colors, palettes,
scales, both theme variants, and logo grob variants
theme.R:
- Remove deprecated legend.text.align and legend.title.align (ggplot2 3.5.0)
- Remove stale @importFrom graphics plot (unused in theme function)
logo.R:
- Fix make_logo_grob() spurious two-row data frame (drop aes/data from canvas)
- Fix add_logo_ga() caption measurement always using first plot; now uses max
across all plots with captions
- Fix add_logo_ga() ncol hardcoded to 2; now uses length(plot_list)
- Fix add_logo_ga() widths silently ignored in nrow > 1 path; now warns
- Replace deprecated qplot() in examples with ggplot() equivalents
- Fix native = T -> TRUE in plot_jpeg()
