The map uses the Natural Earth projection and draws county paths as SVG elements. The code loads GeoJSON data from `data.json` and processes it with the `topojson` library's `feature` function, then projects and renders it using `d3.geoPath` with the `geoNaturalEarth1` projection from D3 v5.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0f7ed866d81e456a9fe14f67cbf571ad?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
