CSCE 5320 - Assignment 6
A scatterplot compares a player’s Games (G) against Hits (H), with point color encoding Position Played and point size encoding HR, across annual frames from a CSV loaded via `d3.csv`. Animated year-by-year playback and mouseover tooltips (delayed 0 ms) show per-player labels. Built with D3 v7, the SVG chart uses `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.scaleSqrt` for axes, colors, and sizing, with axes rendered via `d3.axisBottom` and `d3.axisLeft`.
