{"version":"1.0","type":"rich","title":"Untitled","description":"This example displays a choropleth-style map of the United States using SVG paths. It renders state boundaries and fills each state as a separate path, with a hover effect that turns states red via CSS. The visualization loads TopoJSON data from a remote URL and converts it to GeoJSON using the `topojson.feature` and `topojson.mesh` APIs. It relies on `d3.geoPath` to project and draw the geographic shapes, while `d3.json` fetches the data asynchronously. State borders are drawn as a white stroke overlay for visual separation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a9fd285ea7054f5c87683cb3b2de45e9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
