This visualization displays Australia's electoral districts as colored SVG paths, each filled with a categorical color based on its `Elect_div` property and labeled with the state name centered via `d3.geoPath` centroids. Using `d3.geoMercator` projection and `topojson.feature`, the code loads a TopoJSON file and renders the geometry. State labels are appended as SVG text elements, and the color scale uses `d3.scaleOrdinal` with `schemeCategory10`.
