This example demonstrates how to create an interactive world map using D3.js v5 and TopoJSON. It renders a natural Earth projection with country boundaries, showing country names as hover tooltips and enabling zoom and pan through d3.zoom. The visualization loads geographic data from the world-atlas package, combining TopoJSON geometry with TSV metadata for country names. The map uses an SVG rendering approach, with countries styled as light green polygons that darken on hover, all implemented through d3.geoNaturalEarth1, d3.geoPath, and d3.json.
