This interactive timeline visualizes the historical composition and translation of three key Buddhist sutras—the Heart, Diamond, and Lotus Sutras—from 100 BCE to 649 CE. Selecting a timeline event opens a details panel showing related events and sutra metadata, while a bottom panel presents summary statistics such as the overall time span and translation period. Built with React 19 and D3 v7, the visualization uses `d3.scaleLinear` for axis mapping, `d3.extent` and `d3.group` for statistical calculations, and `ResizeObserver` for responsive rendering. Data is loaded from a CSV file via `d3.csv`.
