This visualization displays a geographic map of India and surrounding regions using a Mercator projection, centered on coordinates [77, 19]. The map renders GeoJSON features as SVG paths, with continents outlined in gray and specific school-type locations highlighted in blue. Built with D3 v5, the code uses `d3.geoMercator()` for projection and `d3.geoPath()` for path generation. The visualization loads data from a local GeoJSON file and renders at a fixed viewBox size of 1400 by 700 pixels.
