Personal Project — Sports Analytics & Interactive Data Visualization
This project explores long-term trends in Major League Baseball performance through interactive visualizations built on historical data from Baseball-Reference. Both pitching and batting statistics are examined across multiple decades, revealing how the game has evolved in its fundamental dynamics — from strikeout rates to batting averages and home run trends.
Built from Baseball-Reference's annual league averages, this chart focuses on key rate statistics — H/9, BB/9, SO/9, and HR/9 — that capture a pitcher's effectiveness independent of playing time. The interactive line chart allows direct comparison across eras, highlighting shifts like the modern strikeout surge and declining hit rates.
A companion visualization using the same methodology applied to batting statistics. Tracking metrics like batting average, on-base percentage, and slugging over time reveals how offensive production has shifted across different eras of the game — from the dead-ball era through the steroid era to today's three-true-outcomes environment.
