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.
