This visualization presents a hierarchical tree of global regions and countries arranged in a tidy radial layout, with the World as the root and continents branching into subregions and nations. Interactivity comes from a zoom behavior that allows users to pan and scale the entire tree. The code uses D3 v5’s `tree` layout and `zoom` API, though the main data-loading and link-drawing logic is commented out, leaving a static gold circle as the only currently rendered visual element. The page loads `data.json` and applies Playfair Display typography.
