{"version":"1.0","type":"rich","title":"Let's make a map with D3.js","description":"This example shows how to create a world map with D3.js, rendering a blue sphere and green country shapes in SVG. The code uses `d3.geoNaturalEarth1` for the map projection and `d3.geoPath` to generate the country outlines from TopoJSON data. It loads the world-atlas dataset from unpkg, converts the TopoJSON to GeoJSON with `topojson.feature`, and appends paths for each country. The visualization is built with D3 v5, using promise-based `d3.json` to asynchronously fetch the geographic data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6c56468f5c98410bb6c2c22c979eea5b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
