This area chart visualizes global population trends over time, using a maroon-filled path to represent the changing values. The visualization loads CSV data from a VizHub dataset and renders it as an SVG, with a time-scaled x-axis and linear y-axis. The code employs D3 v5’s `area` generator, `scaleTime`, `scaleLinear`, and `axisBottom`/`axisLeft` to construct the chart, while custom tick formatting converts large numbers to billions. Gridlines and axis labels enhance readability, and the title sits centered above the plot.
