A world map rendered as SVG paths uses D3.js and the topojson library, with a graticule sphere behind the landmasses. The map responds to mouse clicks and drags through D3's `zoom` interaction, which applies a transform to the country group. Hovering over a country, which is filled with light green and outlined in black, triggers a red fill via the CSS `:hover` pseudo-class. Geographic data comes from the `world-atlas` package, with country names loaded from a TSV file but not yet displayed in the titles.
