This area chart visualizes global population by year, using a smoothed curve to show the overall growth trend. The visualization encodes years on a time-based x-axis and population on a linear y-axis, with the area beneath the curve filled in maroon. The chart is rendered as an SVG using D3 v5 APIs, including `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `area` with `curveBasis`. Data comes from a CSV file on world population statistics, format.
