This visualization displays a choropleth map of Australian electoral regions, with each state filled by a categorical color scale and labeled with its name at the centroid. It uses d3.geoMercator projection and d3.geoPath to render the TopoJSON topology data, while d3.scaleOrdinal with schemeCategory10 assigns colors based on the Elect_div property. The SVG is populated by appending path elements for each feature, with tooltips added via appended title elements.
