This interactive world map visualizes geographic data using multiple map projections. Users can rotate the globe by dragging and switch between Mercator, orthographic, and Albers USA projections by clicking on countries. The visualization renders country boundaries as SVG paths using d3.geoPath, with data from the world-atlas package. A graticule overlays the map, and interactive zooming is enabled through d3.zoom while rotation utilizes d3.drag, both updating the projection's rotate and scale parameters dynamically.
