This area chart displays global population growth over time, using a smooth, filled curve to emphasize the dramatic upward trend. The visualization is built with D3 v5, leveraging `d3.area` with `curveBasis` for the path, and `d3.scaleTime`/`d3.scaleLinear` for axes. Data comes from a CSV of yearly world population figures, parsed and rendered as an SVG. Gridlines and formatted tick labels (e.g., billions) enhance readability, while the maroon fill highlights the area under the curve.
