This bar chart shows the maximum concurrent player counts for four popular video games (PUBG, CSGO, Grand Theft Auto, and Rainbow Six Siege) across the years 2017 to 2021. The chart uses grouped bars, with each game represented by a distinct color, allowing for direct comparison of player counts and yearly trends. The visualization is built with d3.v7 and React, using SVG rendering with `d3.scaleBand` for the categorical axes, `d3.scaleLinear` for the count axis, and `d3.scaleOrdinal` for color mapping. Data is loaded from a CSV file (`maxPlayerCount.csv`) using `d3.csv`.
