Multiple colour scales in choropleth maps with {ggnewscale}

Eukaryota Plantae Chlorophyta Maps

Using multiple colour scales can be a great way to visually differentiate between geographic categories on a map. Here, we demonstrate this by creating a choropleth map to represent the density of plant records from the ALA across bioregions in Australia, and add multiple colour scales to differentiate marine and terrestrial records
