{"version":"1.0","type":"rich","title":"World Map with Population","description":"This example displays a world map choropleth of GDP data, with each country colored according to its economic value. It uses D3 v7 and TopoJSON to load world geography, projecting the map with the `d3.geoNaturalEarth1` projection and rendering countries as SVG paths via `d3.geoPath`. GDP values are fetched from a CSV file, matched to countries through flexible column-name heuristics, and visualized with a color scale. A hover tooltip provides country-specific details, while the map includes a legend for interpreting the color encoding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6e8fc1f534d04a309b2a042671ce9ca0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
