This area chart shows world population growth over time, using a filled path to represent population values across years. The visualization loads CSV data from a remote dataset and maps years to a time scale, with population counts on a linear scale. It uses d3.area with curveBasis for smoothing, d3.axisBottom and d3.axisLeft for labeled axes, and d3.format to abbreviate population numbers. The SVG rendering includes grid lines and clear axis titles, with the population area filled in steel blue.
