Fork of World Countries Tree
This visualization displays a hierarchical tree of world countries, branching from a single "World" root node. The tree layout positions data-loaded country names as connected nodes with horizontal links, where font size decreases with depth. Users can pan and zoom through the SVG rendering using d3.zoom. Built with d3.hierarchy, d3.tree, and d3.linkHorizontal, it loads country IDs from a JSON file and applies a Playfair Display font for text styling.
