This visualization shows the growth of world population over time, with a filled area chart that uses a smooth curve to represent population values. The chart displays time on the x-axis and population on the y-axis, with gridlines and labels for both axes. Built with D3 v5, it uses `scaleTime`, `scaleLinear`, `area`, and `curveBasis` to generate the path, along with `axisLeft` and `axisBottom` for the axes. Data is loaded from a CSV file via `csv`, with population values converted from thousands to raw numbers.
