{"version":"1.0","type":"rich","title":"Mass Map 3 add points","description":"This visualization shows a map of Massachusetts with individual crime locations overlaid as small circular points. The map uses the `geoAlbers` projection and `geoPath` to render state boundaries from TopoJSON data. Crime data is loaded from a CSV using `d3.csv`, with each record plotted via `projection([d.lon, d.lat])` into SVG circle elements. The React component structure manages loading states and renders the map with `d3`-powered geographic utilities, displaying points with a distinct fill color against the state's geometry.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ecdf12f8f6e04ada97d2704d2be9e118?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
