orbis: Interactive and High-Resolution Layered Graphics with Built-in World Maps

A layered grammar of graphics that compiles plots to a resolution-independent scene description and renders it through two back-ends: a self-contained SVG writer with embedded 'JavaScript' for interactive figures (tooltips, hover highlighting, zoom, pan and legend toggling) and R's own graphics devices for publication-quality output at any resolution. Geographic layers are first class: a simplified world polygon dataset ships with the package and can be drawn with several map projections, including Robinson, Equal Earth and an orthographic globe. The layered grammar follows Wickham (2010) <doi:10.1198/jcgs.2009.07098>; projections follow Snyder (1987) <doi:10.3133/pp1395> and, for Equal Earth, Savric, Patterson and Jenny (2019) <doi:10.1080/13658816.2018.1504949>; line simplification uses Douglas and Peucker (1973) <doi:10.3138/FM57-6770-U75U-7727>; the default colour scales follow the guidance on perceptually uniform palettes of Crameri, Shephard and Heron (2020) <doi:10.1038/s41467-020-19160-7>.
