{"version":"1.0","type":"rich","title":"geoTransform Example","description":"This example demonstrates a custom D3 geoTransform that scales a U.S. state map. The projection is defined with a `scale` function that uses `d3.geoTransform` to adjust coordinates around the center of the SVG canvas, shrinking the map to 20% of its original size. State boundaries are loaded from a TopoJSON file, converted to GeoJSON features, and rendered as gray SVG paths. The visualization highlights how custom geographic projections can be created and applied with D3's geoPath, offering a simple way to rescale map data without using a standard projection.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-496078bd5e37fd22a9b43fd6be84b36b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
