KoreaMap
This example displays a choropleth map of South Korea’s provinces, rendered as SVG paths. The visualization uses d3.geoMercator and d3.geoPath to project and draw the geographic features, while React manages the component structure. Data is loaded from a TopoJSON file via d3.json and processed with topojson.feature. Static styling defines the map’s stroke and fill colors. The visualization waits for data to load, showing a loading message until the map is ready.
