This interactive world map allows users to pan and zoom by dragging or using the scroll wheel, with the view transform applied to a group element containing all marks. The visualization renders graticules, country boundaries, and interior borders using d3.geoPath with the natural Earth projection, plus two static city points connected by a red line. Data is sourced from the `world-atlas` TopoJSON and a world cities CSV, with zoom handling implemented through D3's `zoom` behavior within a React component.
