This dendrogram visualizes the hierarchical structure of world countries, organized by continent and subregion, with each node labeled by name. Built with D3 v5, it uses a tree layout and horizontal link generator to position SVG paths and text elements. The visualization supports pan and zoom interaction through D3’s zoom behavior, and applies a Playfair Display font with white text shadows for readability. The hierarchical data is loaded from a JSON file, and font size decreases with depth to indicate level in the tree.
