This map visualizes Australian electorates, coloring each region by its electoral division using a categorical color scale and labeling them with their names. Built with D3 v5 and the topojson library, it processes a Topology JSON file to generate SVG paths via `d3.geoPath` with a Mercator projection. The React-based example uses `d3.scaleOrdinal` with `schemeCategory10` for fills, and positions text labels using centroid calculations from the projection.
