{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map colors countries by their economic classification using an ordinal color scale with the `schemeSpectral` palette. The visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to render world geography, with data loaded from the World Atlas TopoJSON and TSV files via `d3.json` and `d3.tsv`. A custom color legend displays the scale, and zooming is enabled through `d3.zoom`. Hovering highlights a country by turning it red.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7ca206b339914eceb1728f93b7889fee?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
