[Qgis-community-team] Choropleth mapping

[Evan Derickson]

Hi David,

You can use the Graduated symbol renderer to make a choropleth map. The
official documentation on this is at
https://docs.qgis.org/3.16/en/docs/gentle_gis_introduction/vector_attribute_data.html#graduated-symbols,
but you may find something like
https://guides.library.duke.edu/QGIS/Symbolize to be more helpful.

Best,
Evan
