This visualization shows global population growth over time, with an area chart depicting the change in population values across years. The chart uses a maroon filled area with a curved basis line, axis labels, and tick marks, all rendered as SVG by D3 v5. The code creates the area using the `d3.area` generator, which takes the time-scaled x-values and linear-scaled y-values, and it applies the axis functions from `d3.axisLeft` and `d3.axisBottom`. The population data is loaded from a CSV file and formatted with a shortened scale that converts gigabytes to billions, showcasing the trend clearly.
