## Description

The Galton Board App is an interactive probability demonstrator that visualizes the binomial distribution and the Central Limit Theorem through an on-screen Galton board.

Features include a Stock Market Data variant mapping historical monthly returns to bead paths, pause and slow-motion controls, and explanations of related concepts like IID, regression to the mean, law of large numbers, and the Gambler's Fallacy. Presented by Index Fund Advisors, this educational tool is ideal for students, educators, and finance enthusiasts.
