{"version":"1.0","type":"rich","title":"Fork of Choropleth map in D3","description":"A choropleth map of the United States visualizes 2021 county-level poverty estimates, with each state shaded according to its poverty rate using a quantized color scale from light to dark blue. The visualization loads CSV data from a GitHub gist and combines it with TopoJSON geographic boundaries from `us-10m.v1.json`, rendering the map as SVG paths via `d3.geoPath` with an Albers USA projection. A legend generated by `d3.legendColor` displays the unemployment rate scale, while hover effects and tooltips appear through d3 event handlers. Data originates from the U.S. Census Bureau's Small Area Income and Poverty Estimates program.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/01b01140b6f84171b1d810b7ca6b609f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
