{"version":"1.0","type":"rich","title":"Choropleth map","description":"This choropleth map colors world countries by economy type using a spectral color scale, with a hover effect highlighting individual countries and a legend showing the ordinal categories. It renders GeoJSON country outlines as SVG paths via d3.geoPath with a Natural Earth projection, and loads country boundaries from the world-atlas TopoJSON dataset. The map supports zoom and pan through d3.zoom, and the color legend is built with a custom reusable component in d3.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/248ef9f514b64a5d9c5a4c418259f4d4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
