{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map visualizes GDP per capita (PPP, current international $) for 2020 across countries, using a sequential YlGnBu color scale to encode economic output. The map renders with d3.geoNaturalEarth1 and d3.geoPath, while d3.scaleQuantile assigns colors from d3-scale-chromatic’s schemeYlGnBu. Data comes from a World Bank CSV parsed with d3.csvParse, and country boundaries use topojson-client on a world atlas. Gray fills indicate missing GDP values for a given country.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f2199edb602a4a28af5f797381eca5d5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
