		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.
