🏅 OlympiTrack

OlympiTrack is an interactive and insightful data analysis web app for exploring Summer and Winter Olympics over the years. Built using Streamlit, it provides dynamic visualizations and deep insights into athlete dominance, country performance, participation trends, and more — spanning from 1896 to 2024.

📊 About the Data

• Summer Olympics: 1896 to 2024
• Winter Olympics: 1900 to 2014
• The dataset includes the 1906 Intercalated Games, which are not officially recognized in modern medal counts — leading to minor discrepancies from official records.

🛠️ Tech Stack

• Python 3.11+
• Pandas for data manipulation
• Matplotlib and Seaborn for visualizations
• Streamlit for the web interface
• Render for deployment

---

🧠 Challenges Faced

• 🐢 Slow heatmap rendering: Solved by reducing DataFrame size using drop_duplicates(), pivot_table(), and simplifying the visuals
• 🕓 App load time: Improved by removing redundant preprocessing and modularizing logic into helper.py
• 📁 File path issues on Render: Fixed by using relative paths and keeping only production-critical files
• 📉 Medal count discrepancy: Due to inclusion of 1906 games (not part of official Olympic records)
