This area chart displays the cost of sales from 2000 to 2013, using a smooth curved line and a light green filled region beneath it to emphasize trends over time. The visualization is built with D3 v5, using `d3.area` and `d3.line` generators with `curveBasis`, and renders as an SVG. Data is loaded from a CSV file, with the x-axis representing years and the y-axis showing costs, formatted with a compact scale. Axis labels are styled with orange text, while tick values appear in red.
