This interactive visualization presents two maps side-by-side: a world map colored by continent and a US map showing unemployment rates by state. The world map uses `d3.geoNaturalEarth1` projection to display countries from the `world-atlas` dataset, with countries colored via `d3.scaleOrdinal` based on a continent mapping. The US map employs `d3.geoAlbersUsa` projection with the `us-atlas` states dataset, rendering geographic paths through `d3.geoPath`. Both maps include graticule overlays, hover tooltips, and SVG-based rendering with animated state transitions between views.
