This bar chart displays global sales in millions for 29 gaming platforms, ranked by platform name. The visualization uses D3 v6 to load a CSV dataset, scale the data with `d3.scaleLinear` and `d3.scaleBand`, and render the bars as SVG rectangles. Axes are added using `d3.axisBottom` and `d3.axisLeft`, with data joined via D3’s selection methods. The chart highlights platform sales variation, with PS2 leading at over 1.2 billion units.
