{"version":"1.0","type":"rich","title":"[Working with spatial data](https://github.com/enjalot/wwsd)","description":"A choropleth map of UK counties, rendered with Mapbox GL, displays geographic boundaries filled in cyan with dark outlines. The example loads GeoJSON county data via `d3.json` and adds it as a Mapbox GL GeoJSON source, then applies a fill layer with specified paint properties. It adapts a mapbox-gl-js example and uses D3 v3 for data fetching alongside the Mapbox GL JavaScript API.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-42d7dd17cca8d717889d85eb4176b060?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
