{"version":"1.0","type":"rich","title":"Fork of React Starter","description":"A choropleth map of U.S. county unemployment rates colors each county with a blue sequential scale, using a quantize scale with nine bins from 1% to 10%. The visualization loads unemployment data from a CSV file and county and state boundaries from a TopoJSON file. The React app renders an SVG via D3’s `geoPath` projection, with state borders stroked in white and hover tooltips showing county names, state names, and exact rates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1849522fe41c44ae9f7b3fbf775ffe64?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
