This area chart template visualizes world population growth over time, with time on the x-axis and population on the y-axis. The chart is rendered as an SVG using D3 v5, employing `scaleTime`, `scaleLinear`, and the `area` generator with `curveBasis` to create a smooth filled path. The y-axis uses tick formatting to abbreviate large numbers with "B" for billions, while both axes include custom labels. The data comes from a CSV file loaded via `d3.csv`, and the visualization includes gridlines and styled tick marks for readability.
