This chart displays world population growth over time, using a filled area to emphasize the rising trend across years. The visualization is rendered in SVG with D3 v5, employing `d3.area` with `curveBasis` to create the smooth, maroon-filled shape. Time-based x-axis scaling and linear y-axis scaling handle the temporal and numerical data, with a formatted axis that abbreviates billions as "B." Data is loaded from a CSV hosted on VizHub, providing annual population figures.
