A time-series area chart displays global population from 1950 to 2020, with population scaled in billions on the y-axis and years on the x-axis. The visualization uses D3 v5 with SVG rendering, employing `area`, `scaleLinear`, and `scaleTime` to generate a smoothed curve via `curveBasis`. Data originates from the United Nations World Population Prospects 2020, loaded through `dsv` with semicolon separators, and axes are created with `axisBottom` and `axisLeft`.
