{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"This example visualizes U.S. county boundaries as a natural Earth projection map, with the sphere background filled in blue and country shapes rendered in light green. It loads GeoJSON data from a freeCodeCamp choropleth dataset and uses `d3.geoPath` with `d3.geoNaturalEarth1` to project and draw the paths. The code selects an SVG element, appends a sphere path, then joins the TopoJSON features to append individual county paths using D3's data join. The map is static, with no interaction or animation beyond the initial rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/168ffefade10418fb76dd250fb2ac468?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
