This line chart visualizes the cost of sales from 2000 to 2013, using data from a CSV file with yearly cost values. The chart renders as an SVG, with a light green line connecting data points. The visualization is built with D3 v7, utilizing `d3.csv` for data loading and parsing, `d3.scaleBand` for the x-axis, and `d3.scaleLinear` for the y-axis, with the line drawn using `d3.line`.
