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.
