{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map visualizes the world’s countries colored by their economic classification. It renders geographic boundaries from the world-atlas TopoJSON dataset and colors each country using a spectral color scale. The map supports zoom and pan interactions, and hovering highlights a country in red while a tooltip shows its name and economy type. The implementation uses D3’s geoNaturalEarth1 projection, geoPath for map geometry, and a custom SVG color legend built with D3’s ordinal scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a3b683cfeec24f8f8284d5c41505a0cb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
