This geographic map visualizes world landmasses and country boundaries using an Albers equal-area conic projection centered on the United States. The visualization uses React and D3 v5, fetching country topology from the world-atlas library. Land is rendered as filled paths, with graticule lines showing latitude and longitude, and interior boundaries drawn as strokes. The map is displayed as an SVG, using `d3.geoPath` for generating geographic paths and `d3.geoAlbersUsa()` for the projection, with `feature` and `mesh` functions from the topojson library.
