{"version":"1.0","type":"rich","title":"world map for Topojson data","description":"This example displays a world map rendered as filled green countries on a light blue sphere, using Natural Earth projection. It loads TopoJSON data from a GitHub gist and converts it to GeoJSON with `topojson.feature`. The map is drawn as SVG paths using `d3.geoPath` with `d3.geoNaturalEarth1`, while `d3.json` fetches the remote dataset. Country boundaries appear with subtle black strokes, and the sphere outline is generated from a generic GeoJSON sphere object.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/118cddcbb0d046af91dd5c95f82625de?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
