World Countries Tree
This radial-like tree visualization displays a hierarchical dataset of software components and file paths, rendered as a horizontal dendrogram. The layout positions nodes by depth, with links drawn as curved paths. Built with d3 v5, it uses `d3.hierarchy`, `d3.tree`, and `d3.linkHorizontal`, and supports pan and zoom via `d3.zoom`. Node labels show component IDs with font sizes decreasing by depth, styled with the Playfair Display font. The code loads JSON data and renders everything as SVG elements.
