This area chart visualizes world population by year, with a smooth, curved line that fills the area beneath it in maroon. The data originates from a CSV file of world population statistics. The visualization uses D3 version 5, employing `scaleTime` for the x-axis and `scaleLinear` for the y-axis, rendered as an SVG. The chart also includes gridlines and labels for both axes, with the y-axis formatted to display billions (e.g., "7B").
