{"version":"1.0","type":"rich","title":"Geo circle","description":"A world map in the Mercator projection displays two translucent red circles of equal radius, centered at [0, 10] degrees, demonstrating how a 5,000-mile radius appears at different latitudes. The visualization uses d3.geoMercator and d3.geoPath to render the sphere, graticule, and landmasses from TopoJSON world-atlas data, while d3.geoCircle generates the geographic circles. The SVG output includes a white graticule, dark land fill, and country boundaries, with the circles overlaid on the map.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-0fefcd64ca84319643b56ee9e722407f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
