{"version":"1.0","type":"rich","title":"Map Playground","description":"This example visualizes World Bank GDP per capita data for 2020 as a choropleth map, using a natural Earth projection and a quantile color scale with the YlGnBu scheme. Missing data appears gray. The map renders country boundaries from TopoJSON fetched via `topojson.feature`, while CSV data is parsed with `csvParse` and joined to country codes using a `Map`. The visualization uses `d3.geoPath`, `geoNaturalEarth1`, and `d3.scaleQuantile` to encode values as fill colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dc327d8799404fe2b41e34db226f18f7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
