{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map displays the world’s countries colored by their economy classification, with a hover tooltip revealing each country’s name and economic group. The visualization uses `d3.geoPath` with the `geoNaturalEarth1` projection to render the globe, while `topojson.feature` loads the world atlas data and merges it with TSV metadata. An ordinal color scale applies a `schemeSpectral` range, and the custom `colorLegend` component builds an SVG legend. The map supports interactive pan and zoom via `d3.zoom`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9392a3674c9c4fdf86b9c216c6bfe693?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
