This line chart displays the cost of sales from 2000 to 2013, with each year plotted against its corresponding cost value on a linear scale. The visualization uses D3 v7 APIs including `d3.csv` to load data, `d3.scaleBand` for the categorical year axis, `d3.scaleLinear` for the cost axis, and `d3.line` to generate the path geometry with a light green stroke. The chart is rendered as an SVG with axes, labels, and a title, with data coming from a local CSV file.
