{"version":"1.0","type":"rich","title":"map: MI Admin (from shapefile...not working)","description":"This example displays the administrative boundaries of Michigan as an SVG map, rendered using a custom azimuthal equal-area projection. The visualization shows land polygons from a TopoJSON file, which is derived from MapCruzin shapefiles, and includes a graticule and sphere outline for geographic context. It uses `d3.geoPath` to project features, `d3.geoAzimuthalEqualArea` for the projection, and `topojson.feature` to convert the TopoJSON topology into GeoJSON features. The map is built with React, where hovering over a landmass reveals its name via a tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b7806e94f5ab419490698b9166da91d7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
