This area chart visualizes global population growth over time using a maroon filled path with a smooth curve. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, and `area` generator with `curveBasis` to render the SVG path. Axes are drawn with `axisBottom` and `axisLeft`, while population labels use `format` to abbreviate billions. Data comes from a CSV file loaded via `csv` containing yearly world population figures.
