This example shows an interactive world map built with D3 v5, displaying country boundaries and names loaded from the World Atlas TopoJSON and TSV datasets. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and renders countries as SVG paths generated with `d3.geoPath`. Hovering highlights a country in red, and a zoom behavior implemented with `d3.zoom` allows pan and zoom. A light blue sphere background and green country fills demonstrate basic choropleth styling.
