This visualization displays world population growth over time as a filled area chart, using a green semitransparent path. The x-axis maps time (Date objects) and the y-axis maps population counts, formatted with d3’s `format(".1s")` to abbreviate large numbers. Built with D3 v5, it uses `scaleTime`, `scaleLinear`, `area`, `curveBasis`, and `axisBottom`/`axisLeft` to generate the SVG. Data comes from a CSV of world population by year, parsed with `csv()` from D3’s data loading.
