This bar chart displays global sales for video game titles. The code uses D3 v7 to load CSV data, map data to x and y scales, and render SVG rectangles as bars. The chart includes axis labels, a title, a legend, and rotated x-axis tick labels. The data is loaded from a remote gist, and the visualization is structured with a large chart container and D3's margin, scaleBand, and scaleLinear functions.
