This area chart visualizes world population growth over time, using a maroon filled area with a thick stroke to emphasize the upward trend. The chart includes labeled axes for time and population, with population values formatted in billions. Built with D3 v6, the visualization uses `scaleTime`, `scaleLinear`, `area`, and `curveBasis` to generate the smooth area path from CSV data. Axis labels and tick formatting are applied via `axisBottom` and `axisLeft`, with population data sourced from a 2015 world population dataset.
