{"version":"1.0","type":"rich","title":"Topojson World Map","description":"This visualization displays a world map using a Natural Earth projection, rendering continents and countries as filled SVG paths with a blue ocean backdrop. It loads geographic data from the world-atlas TopoJSON file and converts it to GeoJSON using `topojson.feature`. The map applies `d3.geoNaturalEarth1` for projection and `d3.geoPath` to generate the country outlines, with each country filled in green and stroked with a subtle black border.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/38c21a8998e942a1b24f61ee6e2ae4f4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
