This visualization displays world population trends over time as a smooth area chart, with the population values shown on the y-axis and years on the x-axis. It uses D3 v5’s `scaleTime`, `scaleLinear`, `axisLeft`, `axisBottom`, and `area` with a `curveBasis` generator, rendering to an SVG. Data is loaded via `d3.csv` from a VizHub dataset, with the area path filled in maroon and labeled axes using custom tick formatting.
