{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"This example shows a world map rendered with D3.js, displaying country boundaries as light green filled paths against a blue sphere. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to project geographic coordinates onto SVG. Country geometries come from the World Atlas TopoJSON dataset, loaded with `d3.json` and converted using the `feature` method from `topojson`. The map highlights the spherical Earth outline with a separate path styled in CSS, while country strokes appear semi-transparent black.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6b486de3fefc49d7bac60afa0bb4d3ad?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
