{"version":"1.0","type":"rich","title":"BeiJing","description":"This example visualizes the administrative districts of Beijing using a GeoJSON dataset. It renders the district boundaries as SVG paths on a 1600x800 canvas, with each polygon outlined in black and left unfilled. The visualization uses D3.js v6, specifically leveraging `d3.geoNaturalEarth1()` for map projection, `d3.geoPath()` for converting geographic coordinates to SVG path data, and `d3.json()` for loading external data. The code also includes commented-out alternatives for other projections like Mercator and Mollweide, as well as a disabled label overlay.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3b7f6d54b2944e7e9fb460764300e42a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
