This visualization displays global population trends over time, combining a filled area chart with overlaid points to highlight yearly values. The chart uses a time-scaled x-axis and a linear y-axis, with the area rendered using d3.area and curveBasis for smooth transitions. Data comes from a CSV file of world population by year, loaded via d3.csv, and rendered as SVG using d3.scaleTime, d3.scaleLinear, and axis functions. The title and axis labels clarify the chart’s purpose.
