{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"This example demonstrates a world map rendered with D3.js using the geoPolyhedralWaterman projection from d3-geo-projection. It shows country boundaries from a TopoJSON world atlas dataset, overlaid with red rectangles positioned at two specific latitude/longitude coordinates, though the rectangles do not use the map projection and remain in screen space. The visualization uses d3.geoPath to generate SVG paths for countries and a sphere outline, with d3.geoGraticule available for reference lines. The code imports feature from topojson to convert TopoJSON data into GeoJSON features for rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6717d81ca8864428a141816ea543ed9c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
