This interactive map shows world countries with their names displayed as tooltips on hover, and it supports zooming and panning. It renders a natural Earth projection using `d3.geoPath` and `d3.geoNaturalEarth1`, with the sphere filled blue and countries in green that turn red on hover. Country data comes from the `world-atlas` package, with names joined from TSV data, and zoom interactions are handled via `d3.zoom` with event-driven transforms. The visualization is built with D3 v5 and topojson for feature conversion.
