This example shows an interactive world map built with D3 v5, rendered as an SVG using the equirectangular projection. It combines zoom and pan controls with a hover effect that highlights individual countries in yellow. The implementation uses `d3.zoom` for the zoom/pan behavior and `d3.geoPath` for rendering geographical features from TopoJSON data. Custom functions calculate zoom limits and transitions, allowing users to smoothly zoom into specific countries or regions while maintaining boundaries within the viewport.
