This example displays the Salem district map as a stylized line chart, rendering geographic boundaries as bold, teal strokes on a plain background. The visualization uses a React-based architecture with SVG, and the map geometry is processed from TopoJSON data using the `feature` function. The GeoJSON features are projected and drawn through `d3.geoMercator` and `d3.geoPath`, which are called within a React component structure. The underlying data comes from the Data Canvas Sense Your City Dataset, loaded asynchronously via `d3.json` and a custom `useData` hook.
