This line chart visualizes the cost of sales from 2000 to 2013 using data loaded from a CSV file. The chart plots yearly costs as a light green line with thick stroke, using an SVG rendering approach with D3 v7. It employs `d3.scaleBand` for the x-axis years and `d3.scaleLinear` for the y-axis cost values, with `d3.axisBottom` and `d3.axisLeft` providing the ticks. The `d3.line` generator positions each point at the center of its corresponding band.
