This interactive map of Earth uses a natural Earth projection to display world countries, with the code coloring the selected nation in gold while others appear green. Clicking a country reveals its name as a label, while the sphere background is rendered in blue. The visualization loads geographic data from the world-atlas TopoJSON and TSV files, then renders paths via `d3.geoPath` and `d3.geoNaturalEarth1`. It handles selection with D3’s click events, updating fills and text on each interaction using D3 v5.
