This visualization presents a choropleth map of Australia, with each electoral region filled by a categorical color from `d3.scaleOrdinal` and `d3.schemeCategory10`, and labeled with its name. It uses `d3.geoMercator` with custom translation and scale to position the country, while `d3.geoPath` generates SVG paths from TopoJSON data. The map also displays region names via SVG text elements centered on each polygon’s centroid.
