{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"A world map rendered in SVG shows country boundaries as light green paths against a dark blue sphere, using a Natural Earth projection. The code loads world-atlas TopoJSON data from unpkg, converts it to GeoJSON with `topojson.feature`, and draws each country with `d3.geoPath`. The sphere outline is generated from a projected GeoJSON sphere object. D3 v5 handles the asynchronous JSON loading and DOM selection.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f0aeff40b7da46fd8e4d4102704e116f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
