{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"This example uses D3.js v5 to render an interactive-free SVG map of Guangzhou. It draws a blue sphere as a base layer, then projects and displays light green country polygons on top using the Natural Earth projection. The geographic data is loaded from a JSON file provided by geo.datav.aliyun.com, and the topojson library converts it into GeoJSON features. The code leverages `d3.geoNaturalEarth1` for projection and `d3.geoPath` to generate the SVG paths, with styling applied through CSS classes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5754466db9a846a6b619cc092285d9c0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
