tmap.mapgl also features a new layer type,
tm_polygons_3d, which is only available for
"mapbox" and "maplibre".
This map layer is the same as tm_polygons, but one
addition: polygons can be extruded in 3d shape. The visual variable to
control this is called height.
Example
tmap_mode("maplibre")
#> ℹ tmap mode set to "maplibre".
NLD_dist$pop_dens = NLD_dist$population / NLD_dist$area
tm_shape(NLD_dist) +
tm_polygons_3d(height = "pop_dens",
fill = "edu_appl_sci",
fill.scale = tm_scale_intervals(style = "kmeans", values = "-pu_gn"),
fill.legend = tm_legend("Univeristy degree")) +
tm_maplibre(pitch = 45)
#> No legends available in mode "maplibre" for map variables
#> "height"
