Fork of Radial Tree of Countries Hierarchy
This radial tree visualization displays a hierarchical dataset of Korean food categories and dishes, with the root node at the center and branches extending outward. The code uses d3.hierarchy and d3.cluster to compute the tree layout, then renders SVG paths for links and text labels for nodes. Panning and zooming are enabled through d3.zoom, and text font sizes scale with node depth using d3.scaleSqrt. The project function maps polar coordinates to Cartesian positions, while leaf labels rotate and adjust text-anchor based on their angular position.
