{"version":"1.0","type":"rich","title":"Mass School District Boundaries","description":"This example displays the school district boundaries of Massachusetts as an SVG map. The visualization uses a `geoIdentity` projection with `reflectY(true)` to correctly orient the geographic data, and `geoPath` to render the district polygons. Built with React and D3 v5, the map loads TopoJSON data from a local file and converts it to GeoJSON using the TopoJSON library's `feature` function. The map uses a gray fill with teal strokes for the district boundaries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/be84395454464190b4ffe345e4c422e6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
