World Countries Hierarchy
✓ Published1🌍 Public
This radial dendrogram visualizes the hierarchical structure of world countries, organized by continent and subregion. The visualization uses a circular tree layout, with the world at the center and branches extending outward to represent geographic groupings. Country names appear as leaf nodes, with text rotated to follow the radial lines. The code implements this using D3.js v5 APIs, including `d3.cluster` for the tree layout, `d3.linkRadial` for path generation, and `d3.hierarchy` for processing the nested JSON data.
