This bubble chart displays monthly player counts for four games—PUBG, CSGO, Grand Theft Auto V, and Rainbow Six Siege—from September 2017 through December 2021. Each game has its own vertical column of bubbles positioned along the y-axis by player count, with the x-axis grouping the games by name. The visualization uses D3.js v7 to parse the CSV data, create a band scale for the categorical game titles, and a linear scale for the counts. Circles are appended to the SVG canvas within a transformed container group, with axes generated using d3.axisBottom and d3.axisLeft.
