This area chart displays world population growth over time, using a smooth, filled curve to emphasize the overall trend. The visualization is rendered as an SVG using D3 v5, with an area generator that applies a basis curve to create the smooth shape. The axes are configured using `scaleTime` and `scaleLinear`, with formatted tick labels that abbreviate large numbers. Data is loaded from a CSV file containing population figures by year, and the chart includes labeled axes and a title.
