{"version":"1.0","type":"rich","title":"Choropleth Map of County Data","description":"This choropleth map visualizes county-level poverty rates across the United States. The map uses a green color scale, with darker shades indicating higher poverty percentages, and includes a legend with a color gradient. The visualization is rendered as an SVG and built with D3 v5, using `d3.geoPath` to draw county and state boundaries from a TopoJSON file. County data is loaded from a CSV and mapped to colors via `d3.scaleThreshold`, while tooltips display the exact poverty rate for each county.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8720a8f2180e4b0da2cff2e4c7d3181e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
