This area chart visualizes world population growth over time, using an SVG path filled with maroon. The x-axis displays years and the y-axis shows population in billions. The code builds the chart with D3 v5, using `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and the `area` generator with `curveBasis`. Data is loaded as CSV from a VizHub dataset. Axis labels and a title are added via SVG text elements.
