This world population area chart displays the growth of global population over time, using a smooth, maroon-filled area curve. The visualization leverages D3.js v7 functions including `scaleTime`, `scaleLinear`, `area`, `curveBasis`, `axisBottom`, and `axisLeft` within an SVG canvas. The code loads CSV data from a VizHub URL, parses years as dates and populations as numbers, and renders a titled chart with gridlines, axis labels, and formatted tick marks that convert billions (G) to B.
