{"version":"1.0","type":"rich","title":"Chropleth Map","description":"This choropleth map visualizes countries colored by their economic group, using the `d3.geoPath` projection to render the world and a `d3.scaleOrdinal` color scale with `d3.schemeSpectral`. Country data comes from a TopoJSON world atlas, enriched with a TSV file for metadata. A custom legend component displays the color categories, and a `d3.zoom` interaction updates the map’s transform. Hovering over a country reveals its name and economic group via an SVG `title` element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d9b19a5551e6415f82238fcae1423244?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
