This area chart shows world population growth over time from a CSV dataset, using a filled path with a smoothed curve to emphasize the escalating trend. The visualization relies on D3.js v5 functions including `scaleTime` and `scaleLinear` for axes, `area` and `curveBasis` for the filled shape, and `axisLeft`/`axisBottom` for gridlines. Data is loaded via `csv`, parsed into numeric and date values, then rendered as an SVG with custom styling from an external stylesheet.
