{"version":"1.0","type":"rich","title":"Gist 7f1be4fc445f5eab7738096f09be4a9c","description":"This example renders a map of the United States using Mapbox tiles, clipped to the country’s land area. A d3.geo.mercator projection positions the map, while the d3.geo.tile helper computes the visible image tiles at the current zoom level. Tile images from Mapbox’s natural-earth-2 layer are placed in an SVG group clipped by a path of the US land topology, with a black stroke outline drawn over the land boundary. The tile loading adapts to the device pixel ratio, ensuring crisp raster tiles on high-density displays.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-7f1be4fc445f5eab7738096f09be4a9c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
