Choropleth mapping with Leaflet

Dr. Sterling Quinn gives a demo for beginners on how to adapt the Leaflet API's choropleth mapping sample code to your own data. The example used here is COVID-19 vaccination rate across Washington state counties, stored in a GeoJSON file.
Central Washington University offers a GIS Certificate program and a Bachelor of Science degree in Geography with a GIScience specialization. For more information, visit www.cwu.edu/geography/
