{"version":"1.0","type":"rich","title":"[Working with spatial data](https://github.com/enjalot/wwsd)","description":"This example shows a world map with country boundaries and river centerlines rendered as dark gray vector layers over an OpenStreetMap tile base. It demonstrates how to combine Leaflet’s interactive map with D3’s `d3.json` to load GeoJSON data. The map initializes with a global view centered at [30, 0], and each dataset is added as a `L.geoJson` layer with a uniform fill and stroke weight. The code uses Leaflet 0.7.7 and D3 3.5.5, pulling from Natural Earth datasets hosted on GitHub.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-b989c00dd9b7fad477c1d35f525f1d20?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
