Multiple colour scales in choropleth maps with {ggnewscale}

Eukaryota Plantae Chlorophyta Maps

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
