This area chart displays global population trends over time, with a maroon-filled curved path encoding yearly population values from a CSV dataset. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, and `area` generator with `curveBasis` to create the smooth area, while `axisBottom` and `axisLeft` render labeled axes with custom tick formatting. Data is loaded via `csv()` and rendered as SVG, with the y-axis labels shortened from billions to "B".
