+## Motivation
 
 The Olympic Games are often seen as a symbol of fairness: athletes from all around the world competing on equal ground. But are the Olympics really as equal as they appear?
 
 Our project explores how sociocultural, economic, and geopolitical contexts have shaped Olympic participation and success over time. Through a series of interactive visualizations, we investigate how wealth, population, gender representation, politics, and historical events influence the Games.
 
 By combining storytelling with interactive data visualizations, our website reveals the inequalities hidden behind medal counts and Olympic narratives.
