{"version":"1.0","type":"rich","title":"map app","description":"This map app displays world country boundaries using a Mercator projection. It loads geographic data from the World Atlas TopoJSON file via `d3.json`, converts it to GeoJSON with `topojson.feature`, and renders each country as an SVG path using `d3.geoPath` with `d3.geoMercator`. The fixed 900x400 SVG canvas shows the full projection without interactivity or styling beyond default black strokes on a transparent background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c19e3bbba93749478a37a124a64748cb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
