This interactive visualization maps the 28 chapters of the Lotus Sutra into a hierarchical tree, grouped into three major parts that trace the text's narrative arc. Built with React and D3 v7, the tree layout uses `d3.hierarchy` and `d3.tree` to position nodes horizontally, with hover states triggering a detail panel and smooth transitions. The visualization uses warm golden gradients and a color scheme distinguishing each part, while chapter descriptions and summaries appear alongside their corresponding nodes.
