This map shows Massachusetts school district boundaries as a set of geospatial paths. The visualization uses `d3.geoPath` with a `geoIdentity` projection reflected on the Y-axis to render the downloaded TopoJSON data. The React component loads the district features via `useMassGeo`, which converts TopoJSON to GeoJSON using the `feature` function from `topojson`. The SVG paths are drawn with a gray fill and dark teal stroke, scaled to fit a 960 by 500 viewport using `projection.fitExtent`.
