This bar chart displays the top 20 video games by global sales in millions, ranking them from highest to lowest. It uses d3.scaleLinear for the x-axis (sales) and d3.scaleBand for the y-axis (game names), with axes rendered via d3.axisLeft and d3.axisBottom. Data is loaded from a CSV file using d3.csv, and the chart is drawn as SVG rectangles. The code formats sales ticks with d3.format and labels the chart with a title and x-axis caption.
