This visualization displays a hierarchical tree of world regions, showing six top-level areas branching from a single “World” root. The view is rendered as an SVG using D3’s tree layout and horizontal link generator, with region names positioned along the branches. Text size scales inversely with depth. The implementation uses d3.hierarchy, d3.tree, and d3.linkHorizontal, and supports pan-and-zoom via d3.zoom. Data comes from a static JSON file containing only the six continent-level nodes, styled with a serif font and green links.
