This area chart visualizes world population over time, using a smooth curved path filled in maroon against a light gray grid. The D3 v5 code loads CSV data from a VizHub dataset and parses the year as a date and population as a number. It employs `scaleTime` for the x-axis, `scaleLinear` for the y-axis, and an `area` generator with `curveBasis` to create the filled shape. Axis labels and a title are added as SVG text elements.
