This area chart visualizes world population growth over time, with the x-axis representing years and the y-axis showing population counts in billions. The data comes from a CSV file loaded via `d3.csv` from VizHub. The chart uses `d3.area` with `curveBasis` to create a smooth filled path, `scaleTime` and `scaleLinear` for axes, and `axisBottom` and `axisLeft` with custom tick formatting. The maroon-filled area sits against a minimal SVG canvas, with styled text labels for the title and axes.
