{"version":"1.0","type":"rich","title":"Fork of Choropleth Map","description":"This choropleth map visualizes GDP per capita (PPP, current international $) by country, using data from the World Bank’s 2020 dataset. It renders countries as geographic paths via `d3.geoPath`, fills them with a sequential color scale (`d3.scaleQuantile` and `schemeYlGnBu`), and marks missing values in gray. The code fetches TopoJSON world atlas boundaries and a CSV dataset, then combines them using `topojson-client` and `d3.csvParse`. Natural Earth projection and graticule lines provide geographic context.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/be7e9237e56b4e719201429aab656444?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
