This scatter plot visualizes world population growth from 1960 to 2015, using a filled area chart beneath a red dot for each year. The visualization employs d3.scaleTime and d3.scaleLinear for axes, d3.area with curveBasis for the smooth region, and d3.axisBottom/axisLeft with tick formatting. Data loads from a CSV file via d3.csv. The SVG rendering includes labeled axes and a title, with population values formatted in billions.
