This interactive D3.js visualization presents the Noble Eightfold Path as a hierarchical tree with three color-coded categories—Moral Virtue, Meditation, and Wisdom—branching into eight specific practices. It uses `d3.tree()` and `d3.hierarchy()` to compute node positions, with `d3.linkVertical()` generating curved paths between nodes. Text labels include Pali terms and supporting background rectangles for readability, while hover effects highlight individual nodes. The SVG rendering includes custom node positioning and responsive layout adjustments.
