This chart visualizes world population over time using an area chart, with time on the x-axis and population on the y-axis, presented in billions. The data comes from a CSV file loaded via `d3.csv`, with dates parsed into JavaScript `Date` objects. The visualization uses `d3.scaleTime`, `d3.scaleLinear`, and `d3.area` with a `curveBasis` smoothing, while axes are generated with `d3.axisBottom` and `d3.axisLeft`. The SVG rendering includes a maroon filled area, axis gridlines, and a title, all styled with CSS.
