{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"This example displays a world map with country boundaries and a graticule overlay, rendered as SVG using D3.js v5. It shows countries as light green polygons with subtle black strokes against a blue sphere background. The code uses `d3.geoNaturalEarth1()` for projection, `d3.geoPath()` for path generation, and TopoJSON’s `feature` method to convert World Atlas TopoJSON data (from unpkg) into GeoJSON. A graticule is drawn with `geoGraticule`, and the sphere outline is generated via `pathGenerator({type: 'Sphere'})`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/39dbe3d8e92f49e2b01294d8f5c2ea30?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
