This area chart visualizes world population growth over time, with a smooth orange filled region beneath the curve. The x-axis displays years as time scales, while the y-axis shows population counts formatted in billions. Built with D3 v5 in a React framework, the chart uses `scaleTime`, `scaleLinear`, and `area` with `curveBasis` to generate the path. Data comes from a CSV file of world population by year, rendered as an SVG with custom axis labels and gridlines.
