{"version":"1.0","type":"rich","title":"Fork of Choropleth Map","description":"This choropleth map visualizes educational attainment across U.S. counties, using d3.scaleThreshold with a green color scale to encode the percentage of residents with bachelor’s degrees or higher. County boundaries are rendered as SVG paths via d3.geoPath and a geoAlbersUsa projection, with data loaded from FreeCodeCamp’s TopoJSON and JSON datasets. The map supports pan and zoom through d3.zoom, and includes a color legend built with reusable custom D3 components. Hovering highlights individual counties by changing their fill color.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1210967677e5487b80fb792894343271?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
