🏅 Olympic Games Data Analysis and Visualization (R Project)

This project uses R programming to perform an in-depth analysis of historical Olympic Games datasets. It focuses on exploring athlete performances, country rankings, medal trends, and participation patterns over time. Through powerful data wrangling and visualization techniques, the project uncovers fascinating insights into the evolution of the Olympic Games.

🚀 Project Highlights

• 📊 Exploratory Data Analysis (EDA) on athlete and event data
• 🏆 Trends in medal counts by country and sport
• 📅 Participation growth analysis across decades
• 🎯 Statistical summaries and outlier detection
• 📈 Data visualizations including line charts, bar plots, scatterplots, and heatmaps
• 📍 Mapping geographic medal distributions

🛠 Tech Stack

• R Programming
• Tidyverse (dplyr, tidyr, ggplot2)
• readr / data.table
• ggplot2 / plotly
• leaflet (for maps)
• Shiny (optional for interactive dashboard extension)
