This visualization displays the sales figures of bestselling video games as a horizontal bar chart, with game titles on the Y-axis and sales numbers on the X-axis. It uses D3.js v6 with scaleLinear for the numeric sales axis and scaleBand for categorical game titles, rendering bars as SVG rectangles. Data is loaded from a CSV file using the d3.csv method, and the chart includes formatted axis ticks that abbreviate large numbers (e.g., converting millions to billions) via d3.format.
