This visualization displays the Buddhist Noble Eightfold Path as a hierarchical tree, organized into three main categories (Moral Virtue, Meditation, and Wisdom) with their eight constituent elements. Using D3.js v7, the code constructs an SVG rendering with custom radial gradients, symmetrical node positioning, and hover interactions that highlight nodes and links. The visualization includes descriptive tooltips, text backgrounds, and responsive layout adjustments, all styled with a warm earth-tone color palette defined in CSS custom properties.
