This interactive force-directed graph maps the historical relationships among schools of Buddhism. Using d3.forceSimulation with SVG rendering, it positions nodes by tradition—Theravāda, Mahāyāna, Vajrayāna, and early schools—color-coded and sized by significance. Clicking any node updates an adjacent info panel with the school’s name, geographic location, and description. Filter buttons highlight each tradition or show all nodes, while links trace lineage from early Buddhism through major branches and sub-schools.
