This area chart visualizes world population by year, sourced from a World Population dataset. Using D3 v5, it renders an SVG path with an area generator and curveBasis for smooth filling, paired with scaleTime and scaleLinear axes. The chart includes formatted y-axis labels (e.g., "B" for billions), gridlines via tickSize, and styled title and axis text. Data is loaded from a CSV and parsed into date and numeric values for plotting.
