A choropleth map displays Massachusetts school district boundaries as gray polygons with teal outlines. The visualization uses a topojson data source loaded via `d3.json` and converted to GeoJSON features with `topojson.feature`. React manages the component state while `d3.geoPath` with a `geoIdentity` projection renders the shapes, using `reflectY(true)` to correctly orient the map coordinates. The SVG output is scaled to fit a 960×500 viewport using `projection.fitExtent`.

Mass School District Boundaries

This example displays the boundaries of Massachusetts school districts as a light gray-and-teal choropleth map. It loads TopoJSON data from a GitHub gist and converts it to GeoJSON features using the TopoJSON library. The map is rendered in SVG with React, and the D3 geoPath and geoIdentity projection with reflectY flip the coordinates to orient the state correctly. The visualization focuses on crisp geographic outlines without additional thematic encoding, serving as a base layer for potential district-level analysis.

Mass School District Boundaries

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`.

Mass School District Boundaries

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.

Mass School District Boundaries

This visualization maps school district boundaries across Massachusetts using a topojson-derived GeoJSON dataset. Built with React, the app loads geographic data via d3.json and converts it with topojson.feature, then renders each district path using d3.geoPath. The map uses an inverted y-axis via geoIdentity’s reflectY method, with districts drawn in flat gray and teal strokes against a 960x500 SVG canvas.

Mass School District Boundaries

This example displays the boundaries of Massachusetts school districts as a static SVG map. The visualization renders geographic features using `d3.geoIdentity` and `d3.geoPath`, with TopoJSON data converted via the `feature` function. The map presents district outlines in a light gray fill with teal strokes, projecting the geographic coordinates to fit a 960 by 500 pixel viewport. The visualization is built with React and leverages `d3.json` to load the MassGeo dataset from a remote GitHub Gist.
