This example shows a hierarchical dataset of global regions and countries, organized as a tree structure with the root labeled "Amusement & Recreational Venue." It renders an SVG dendrogram using D3's `tree()` and `hierarchy()` layouts, with `linkHorizontal()` generating curved connector paths. The visualization supports pan and zoom via `d3.zoom`, and node labels display at varying font sizes based on depth. Data comes from `data.json`, and text styling uses the Playfair Display font.
