{"version":"1.0","type":"rich","title":"Let's make a map with D3.js","description":"This example shows a world map rendered as an SVG using D3.js, with countries filled in light green against a sky-blue sphere background. It uses the `geoNaturalEarth1` projection and `geoPath` to draw country boundaries from TopoJSON data loaded from the world-atlas package. The code fetches the countries-110m.json file, converts it to GeoJSON with `feature`, and appends each path to an SVG element. Both D3 v5 and TopoJSON are loaded via CDN, and the visualization is built with a React starter setup.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/07df0fcd37c84a1fb506c449d9a915b4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
