This area chart visualizes the cost of sales from 2000 to 2013, with a green filled area beneath a black curved line. Time is plotted on the x-axis and cost on the y-axis, with red tick labels and orange axis labels. The visualization uses d3.scaleTime, d3.scaleLinear, d3.line, and d3.area with a curveBasis interpolation, rendering to SVG. Data is loaded from a CSV file via d3.csv and formatted using d3.format.
