This visualization displays neighborhood boundaries in Portland using a geometric map projection. The map renders geographic features as red-outlined polygons, with the page title “portland” appearing above the SVG canvas. The code applies `geoConicEqualArea` for projection and `geoPath` to draw the shapes, while `topojson.feature` converts the TopoJSON data into GeoJSON. The data comes from a PortlandNeighborhoods.json file hosted on GitHub, and the visualization is built with React and styled with Poppins typography.
