This visualization shows global population trends over time as a filled area chart, with the x-axis mapping years and the y-axis representing population counts. The chart uses an area generator from D3 v5 to create a smooth, curved region beneath the line, rendered as SVG paths. Data is loaded from a CSV file using `d3.csv`, with population values scaled by 1000 and years parsed as dates. Axes are configured with `d3.axisBottom` and `d3.axisLeft`, while `d3.scaleTime` and `d3.scaleLinear` handle the scales for time and population.
