{"version":"1.0","type":"rich","title":"d3 choropleth map","description":"This choropleth map visualizes the estimated number of people in poverty per U.S. county for 2021, using a logarithmic color scale from white to dark orange. Hovering over a county reveals its exact poverty count via a tooltip. Built with D3 v5, the map uses `d3.geoPath` and `d3.scaleThreshold`, drawing county and state boundaries from topojson data, with a legend and color encoding derived from the `d3-scale-chromatic` scheme. The poverty data is loaded from a CSV containing FIPS codes and county-level values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c27d0980d89d4d48a6b712282d87a776?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
