{"version":"1.0","type":"rich","title":"Base US Map","description":"This example displays a base map of the United States with its state boundaries rendered as semi-transparent white polygons with black strokes. The visualization uses a React component that fetches TopoJSON data from the us-atlas CDN and converts it to GeoJSON features using the `feature` and `mesh` functions from the TopoJSON library. The map is drawn with SVG paths created by `d3.geoPath` and the `geoAlbers` projection, which is applied to each state feature in the `Marks` component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/984ff50a947f4cbc8aa09b0c1fc9fa81?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
