This visualization shows a map of Portland neighborhoods using a conic equal-area projection, rendered as stroked SVG paths. It uses `d3.geoPath` to project and draw the neighborhood boundaries from TopoJSON data, with the geographic projection centered on Portland. The map is displayed in a React component that fetches and parses the data via `d3.json` and `topojson.feature`. The styling applies a teal stroke to the paths, creating a clean, minimal map view.
