This interactive map displays world country boundaries using a draggable orthographic projection within an SVG. Users can click individual countries to toggle the view between the orthographic and Mercator projections. The visualization leverages d3.geoPath, d3.geoOrthographic, and d3.geoMercator from d3-geo-projection, with topojson for country features and world-atlas data. Drag interactions rotate the globe via projection.rotate, while zoom transformations adjust the SVG group. Country names are loaded from a TSV file and applied on click.
