This area chart visualizes world population growth over time, using a smooth, curved path filled in maroon to represent the data. The visualization employs D3 v6 APIs including `scaleTime`, `scaleLinear`, and `area` with `curveBasis` to render the SVG. The y-axis labels are formatted using `format` to abbreviate billions, and the chart includes labeled axes and a title. Data comes from a CSV file of world population by year, loaded via D3's `csv` method.
