{"version":"1.0","type":"rich","title":"Let's make a map with D3.js","description":"This example displays a world map rendered as an SVG, with countries filled in green against a dark blue spherical backdrop. It fetches country boundaries from a TopoJSON file via the world-atlas dataset, then projects them using the Hufnagel projection from `d3-geo-projection`. The code builds paths with `d3.geoPath` and `d3.json`, styling the sphere and landmasses through CSS classes. It relies on D3 v5, TopoJSON’s `feature` method, and demonstrates a compact, data-driven mapping workflow.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/12eedb6c0850435b9d7b396b8bef2db6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
