{"version":"1.0","type":"rich","title":"Choropleth map","description":"A choropleth map of the United States displays the percentage of the population living in poverty for each county in 2021. The map uses a sequential red color scale, from light to deep red, to encode the poverty rate, with a legend showing values from 0% to 25% in five-point increments. The visualization is rendered as an SVG using D3.js v7, where the `d3.geoAlbersUsa()` projection and `d3.geoPath()` draw the county boundaries from a GeoJSON file. The poverty data is loaded from a CSV file and joined to the geographic features via their FIPS code.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3af9509071444a58b328aaa78e3eb896?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
