{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map colors countries by their economic classification, using a spectral color scale and an interactive legend to indicate the mapping. Users can zoom and pan the map, which is rendered with SVG paths generated by the `d3.geoPath` and `geoMercator` projections. The visualization loads country boundaries and metadata from the world-atlas TopoJSON and TSV files, processed via the `topojson` library. Hovering over a country highlights it in red and displays its name and economy in a tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cf733f7a343e498887bc29c34f130023?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
