This area chart shows the total world population from 1970 to 2022, summing population values across all countries for each year. The x-axis displays years, while the y-axis represents people, formatted with SI prefixes. Built with D3 v7, it loads CSV data, filters year-specific columns, and uses `d3.area` with a monotone curve to render the filled path. Axes are generated with `d3.axisBottom` and `d3.axisLeft`, and the SVG output includes labeled axes.
