{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"This example shows a world map rendered with an equal-area natural Earth projection, with each country filled in light green and outlined with subtle black strokes against a blue sphere background. The visualization loads geographic data from the world-atlas TopoJSON dataset and converts it to GeoJSON features using the `feature` function from TopoJSON. The map is drawn as SVG paths generated with D3's `geoPath` and `geoNaturalEarth1` projection APIs, demonstrating a minimal React-free D3 mapping workflow.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d52131868fa14aa6aec9ed3f01ef38eb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
