{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"A D3.js map renders world countries as light-green SVG paths atop a blue sphere, using the Natural Earth projection. The code loads GeoJSON from the world-atlas TopoJSON source, converts it with the `feature` method, and draws each country with `geoPath`. The sphere outline is generated from a spherical geometry object, while CSS applies fill and stroke styling. This example demonstrates a minimal choropleth-free geographic visualization, relying on `json`, `geoNaturalEarth1`, and `topojson` to project and display the data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0795c7f9410b410188b9712128804d31?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
