{"version":"1.0","type":"rich","title":"Choropleth Map","description":"This choropleth map colors world countries by economic category using a sequential spectral color scale. The visualization, rendered as SVG with D3 v5, uses `d3.geoEqualEarth` projection and `d3.geoPath` to draw country boundaries from TopoJSON data sourced from the World Atlas. Users can pan and zoom via `d3.zoom`, while a legend built with custom D3 selections displays the color scale. Hovering highlights individual countries in red, and tooltips show country name and economic value.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5338f92466564c56aa9564f8254f7b77?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
