{"version":"1.0","type":"rich","title":"Mass Map 2","description":"This map displays Massachusetts school districts as geographic regions, using an equal Earth projection to draw each district boundary. The visualization loads TopoJSON data from a GitHub source, then converts it to GeoJSON using the `feature` function before rendering paths with `d3.geoPath`. The map is built with React components and D3 v5, with SVG paths styled using teal strokes and fills from the associated CSS file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c877e5c3eb7e4292a9f3859a2108b5a2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
