{"version":"1.0","type":"rich","title":"Let's Make a Map","description":"This example demonstrates how to load and prepare geographic data for mapping. The page renders an empty SVG canvas and uses D3's `select` and `json` functions to request a world-atlas TopoJSON file from a remote URL. The code then applies the `topojson.feature` API to convert the raw TopoJSON geometry into GeoJSON feature objects for the world's countries. While the resulting shapes are not yet drawn, the visualization establishes the data pipeline for a future map projection and rendering step.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f21f2f2a3a424298a8b59c2742e64cb9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
