This area chart visualizes world population growth over time, with the x-axis representing years and the y-axis showing population counts. The chart uses a smooth, curved area fill to emphasize the overall trend of population increase. Built with D3 v5, it employs `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and the `area` generator with `curveBasis` for the smoothed path. The data, loaded from a CSV via `d3.csv` and mapped to `Date` and numeric values, is rendered as an SVG.
