The visualization displays a world map of ICE-8, using a geoNaturalEarth1 projection to render continents as filled countries with distinct borders. It employs d3.geoPath to generate SVG paths for the sphere and country boundaries, while the topojson feature function extracts geographic features from a world-atlas JSON dataset. The map uses color-coded fills—purple for the sphere and teal for landmasses—to highlight the global distribution of the ICE-8 phenomenon, with the data sourced from the countries-110m.json file.
