This example visualizes video game sales across categories using an area chart, with sales figures plotted on the y-axis and categorical labels on the x-axis. The chart uses D3 v7 to create a smooth area path, with the area filled in steelblue to emphasize the distribution of sales values. The code demonstrates D3’s scaleLinear for both axes, an area generator to define the shape, and axis generators (axisBottom, axisLeft) with rotated tick labels for category readability. Sales data is embedded directly in the script, and the rendering is done in SVG, with margins and labels for clarity.
