{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map colors each country according to its economy category, using an ordinal color scale with a spectral scheme. The visualization loads world geography from TopoJSON and country metadata from TSV, then renders the map as SVG paths with a natural Earth projection. Hovering highlights a country in red, and a custom color legend displays the category colors. The map supports zooming and panning through d3.zoom, with d3.geoPath generating the geographic shapes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/76619d54f6c243aba7ef0261e629e3ac?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
