{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"This example demonstrates how to create a world map using D3.js, displaying countries as red polygons with white strokes against a blue spherical backdrop. The visualization uses a Natural Earth projection via `d3.geoNaturalEarth1` and renders geographic features with `d3.geoPath`. Country boundaries come from the World Atlas TopoJSON dataset (110m resolution), which is loaded asynchronously and converted to GeoJSON using `topojson.feature`. The SVG elements are styled through CSS, with the sphere filled in blue and country borders outlined in black.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e0671dbbacb742d69ef50d4f1586cee2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
