ggplotstyle

ggplotstyle is a collection of design guidelines and tools for ggplot2 that standardizes visual styling across plots. It provides a set of themes, color palettes, and typography recommendations intended to improve readability and visual consistency in scientific and data journalism work.

Origin and scope: developed by a community of data visualization practitioners and statisticians, ggplotstyle aims to complement ggplot2’s flexible grammar by offering pre-defined, publication-ready aesthetics. The project emphasizes perceptually uniform color scales, balanced gridlines, and clear legends, while preserving the ability to customize as needed.

Components: core components include named themes (for example "clean," "bold," or "muted"), color palettes designed for accessibility and perceptual uniformity, and typographic guidelines covering font sizes and line spacing. It also provides helper functions to adjust axes, facets, and annotations, and sets defaults for legends, facet spacing, and panel backgrounds to maintain consistency across plots.

Usage: after installation, users can apply a style globally or per plot. A typical workflow involves selecting a style and then adding data layers as usual; the style sets a ggplot theme, a color scale, and recommended guides. The aim is to reduce repetitive styling while enabling quick, publication-grade visuals.

Impact and reception: ggplotstyle is used in academic and media settings where consistency matters. Critics note that rigid styles can obscure data-specific needs, so it is recommended to treat styles as a starting point and adjust as necessary. It remains compatible with standard ggplot2 components and workflows.
