{"version":"1.0","type":"rich","title":"GDP World Map","description":"This world map visualizes geographic GDP data using a choropleth approach, coloring countries by their economic output. The example loads GeoJSON map data and renders it as SVG paths with `d3.geoPath`, while numeric GDP values drive a color scale. It uses `d3.json` to fetch the dataset and `d3.scaleThreshold` to map values to fill colors, with a tooltip providing details on hover. Built with D3 v6, the visualization demonstrates basic geographic mapping and data-driven styling in an SVG container.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/abdbaed2ed814d26b48f4fa9a2041fb8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
