A line chart displays the cost of sales from 2000 to 2013 using data from a CSV file. The SVG visualization, built with D3 v7, maps years on a band scale and costs on a linear scale, drawing a light green path via `d3.line()`. Both axes are generated with `d3.axisBottom` and `d3.axisLeft`, accompanied by red axis labels. The chart highlights annual cost fluctuations, peaking in 2007 and showing notable variability across the period.
