This interactive D3.js v7 visualization presents Buddha’s teachings as a hierarchical radial tree, with the core teaching at the center branching outward through concepts like the Four Noble Truths and Dependent Origination. Using d3.cluster, the layout positions nodes in a full circle, with curved links and text labels adjusted for orientation. The code implements zoom and pan via d3.zoom, supports responsive resizing, and renders all elements as SVG. Data is loaded from a local JSON file using d3.json.
