This example visualizes global population growth from 1960 to 2015 using an SVG area chart with red fill. The chart displays population on the y-axis and date on the x-axis, with axis labels and tick lines rendered via `axisLeft` and `axisBottom`. The code uses D3 v5’s `scaleTime`, `scaleLinear`, `area`, and `csv` to load and map the data, while a custom tick formatter converts population values to billions. The visualization also includes a title and subtle grid lines created through tick size adjustments.
