This area chart visualizes world population growth over time using a maroon-filled curve with a thick black stroke. The code loads CSV data, parses years as dates, and employs d3.area with a curveBasis generator to render the smooth path. Axes are created using d3.axisLeft and d3.axisBottom, with formatted tick labels from d3.format. The SVG rendering relies on d3.scaleTime and d3.scaleLinear, and the chart includes labeled axes and a centered title.
