An animated orthographic choropleth map displays the dominant religion of each country, with a color-coded legend that responds to hover. The globe rotates continuously as the user inspects the data. Built with D3.js, it uses `geoOrthographic`, `geoPath`, `geoGraticule`, and `scaleOrdinal` to project and style the map from a TopoJSON world atlas and a CSV of per-country religious demographics. The legend is generated by a custom `colorLegend` function.
