This area chart displays the cost of sales from 2000 to 2013, using a smooth, filled curve to emphasize the trend over time. The SVG visualization is built with D3 v5, employing `scaleTime` and `scaleLinear` for the axes, and the `area` and `line` generators with `curveBasis` for the smoothed path. The chart loads data from a CSV file and uses custom axis labels and styling to highlight values, with red tick labels and a light green area fill.
