This interactive bubble chart visualizes the relationship between video game review scores, average hours played, and copies sold. Each circle represents a game, positioned along the x-axis by review score and y-axis by play time, with circle size encoding sales volume. Color distinguishes game genre, and hovering reveals a tooltip with exact details. Built with D3.js, the visualization uses `scaleLinear`, `scaleSqrt`, and `scaleOrdinal` for encoding, while `join('circle')` renders the animated bubbles. Data is loaded from a GitHub Gist CSV file, and the SVG output includes legends for size and genre.
