This D3 scatter plot visualizes top video game sales, mapping release year on the x-axis against global sales in millions on the y-axis. Each circle represents a game, with its position determined by the `scaleLinear` scales and `extent` functions, while `axisLeft` and `axisBottom` render the axes. The SVG is sized to the browser window, and data is loaded from a CSV via `d3.csv`, with rows parsed to convert numeric strings to numbers. The plot fills the viewport, allowing exploration of sales trends across gaming history.
