{"version":"1.0","type":"rich","title":"Choropleth Map","description":"A choropleth map colors countries by economy classification, using a spectral ordinal scale. The visualization loads geographic data from the World Atlas TopoJSON and TSV files, projecting it with a natural Earth projection via `d3.geoPath`. Users can pan and zoom through the `d3.zoom` behavior, while a color legend built with custom SVG elements displays the categories. Hovering highlights countries in red, and tooltips show each country’s name and economic group.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b84b5dffff384a9e98af78749305070d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
