This area chart visualizes world population growth over time, using a smooth, filled curve to depict the changing values. The chart plots population on the y-axis and years on the x-axis, with gridlines and axis labels for clarity. Built with D3 v5, the visualization uses the `area` generator and `curveBasis` for the filled path, while `scaleTime` and `scaleLinear` handle the axes. Data is loaded from a CSV file containing historical population figures by year, and the chart is rendered as an SVG with styled text and gridlines.
