A vertical timeline traces the historical development of three key Buddhist sutras, from early Prajñāpāramitā texts around 100 BCE to Kumārajīva’s and Xuanzang’s translations in the fifth and seventh centuries. Color-coded events for the Diamond, Lotus, and Heart Sutras are plotted along a gradient line, with clicking an event opening a glass-morphism details panel and filtering related points. The visualization uses React to manage interactive state and D3 (via `d3.scaleLinear`, `d3.extent`, and the `join` API) to render SVG elements and handle mouse events. Statistical insights in a lower panel summarize the time span, sutra count, and composition and translation periods.
