This area chart visualizes global population growth over time, mapping yearly population counts to a filled curve with a smooth basis interpolation. The SVG rendering uses D3 v5 scales—`scaleTime` for the temporal x-axis and `scaleLinear` for population values—with axes generated via `axisBottom` and `axisLeft`. Data loads from a CSV file using `d3.csv`, and the `area` generator with `curveBasis` creates the shaded region. The chart includes formatted tick labels (e.g., abbreviating billions) and styled axis annotations.
