{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map colors countries by their economy type using a categorical color scale, with a legend showing each category. It renders world geography as SVG paths via `d3.geoPath` and the Natural Earth projection, while `d3.zoom` enables panning and zooming. The code loads TopoJSON and TSV data from the world-atlas package, mapping country IDs to economy labels, and uses `d3.scaleOrdinal` with `schemeSpectral`. Hovering highlights a country in red.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/951ab548690a498da39f309ef12b5752?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
