This area chart depicts the growth of world population over time, using data from a CSV file that records population values by year. The chart renders as an SVG with a filled area beneath a curve, with axes labeled “Year” and “Population.” It uses d3.csv to load data, d3.scaleTime and d3.scaleLinear for scales, and d3.area with curveBasis to generate the curved path, while d3.axisBottom and d3.axisLeft create the gridlines and tick labels.
