{"version":"1.0","type":"rich","title":"Let's make a map with D3.js","description":"This example shows a world map rendered as SVG paths, with countries filled in navy blue and outlined with light green strokes. The map uses the Mercator projection via `d3.geoMercator` and draws features with `d3.geoPath`. Geographic data comes from the World Atlas TopoJSON file, which is loaded with `d3.json` and converted to GeoJSON using `topojson.feature`. The styling is applied through CSS on the `path` elements, and the visualization updates once the data is fetched asynchronously.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c38e9fb034964bbd8b068f98b523ad2b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
