World Population: Area Chart
This area chart displays simulated world population figures from 2020 to 2025, with values declining from 5,541 to 5,497. The visualization uses D3 v5 with SVG rendering, employing `scaleTime` for the x-axis and `scaleLinear` for the y-axis. The code builds the chart using `area`, `axisBottom`, and `axisLeft`, with gridlines and rotated axis labels. The Finnish title and comic-style font indicate a localized example, while the data appears to be sample values rather than real demographic records.
