This visualization displays the electoral divisions of Australia, with each region filled by a distinct color from d3.scaleOrdinal and d3.schemeCategory10. The map uses d3.geoMercator, d3.geoPath, and topojson.feature to project and render the topology from australia.json. State names are overlaid at each polygon’s centroid using d3 pathGenerator.centroid. Borders are highlighted in green with thick strokes via CSS.
