A choropleth map of Australia renders electoral boundaries with a categorical color scale, displaying state names at region centroids. The visualization uses D3.js version 5 with the geoMercator projection and geoPath generator to project TopoJSON data into SVG paths. The code applies a ten-color ordinal scale based on electoral division properties, with state name labels positioned via the projection's centroid method. The React framework loads geographic data from a GitHub gist, styling state boundaries with black strokes and white fills.
