State of the a-R-t - Advances in mapping in R
summary
Claims a usable R→browser pipeline that renders millions of points and interactive 3D polygons by combining R, HTMLwidgets, Mapbox and deck.gl. Releases mapdeck and a pseudo-GeoJSON format that supports multiple geometries per feature and roundtrips clicks back into R. Rewrites core in C++ rewrite, dropping a render step from ~70s to ~4s and demoing 1.6s for one million generated points. Works in macOS browsers; some JavaScript/Ubuntu glitches remain.
