This area chart displays world population growth by year, using a maroon-filled path over time to show the rising trend. It loads CSV data from a VizHub dataset, parses the year and population values, and renders an SVG chart with D3 v5. The code uses `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.area` with `curveBasis` for the smooth filled shape, and `d3.axisLeft` and `d3.axisBottom` for labeled gridlines.
