Fork of test Choropleth map in D3
This choropleth map visualizes 2021 poverty estimates across U.S. counties and states using a blue sequential color scale. It displays data from the Census Bureau’s Small Area Income and Poverty Estimates program, with unemployment rates mapped to geographic regions. The visualization uses D3 v6 and the topojson library to project and render the map, employing `d3.geoAlbersUsa()` for the projection and `d3.geoPath()` to draw shapes. An interactive tooltip appears on hover, revealing each county’s name and poverty rate.
