A9 Choropleth Map
✓ Published0🌍 Public
This choropleth map visualizes state-level unemployment rates in the United States for 2021, using a blue sequential color scale to encode rate differences. Built with D3 v7, it renders the contiguous states and Alaska via `d3.geoAlbersUsa` and `d3.geoPath`, with data from the USDA’s county-level dataset. Hovering over a state triggers a basic tooltip showing the state name and unemployment value.
