This example displays a choropleth map of Australia’s administrative regions, rendered as red-filled paths with white strokes on an SVG canvas. It uses d3.geoMercator with a clipped projection and d3.geoPath to draw the features, while topojson’s feature method converts the loaded state and district datasets into GeoJSON. The map supports zooming via d3.zoom, and d3.scaleOrdinal with schemeCategory10 assigns categorical colors, though the current styling overrides fills with a uniform red.
