This area chart visualizes world population growth from historical data, using a smooth curved line filled in maroon to show changes over time. The chart displays population values on the y-axis and time on the x-axis, with gridlines and labeled axes for clarity. Built with D3 v5, the visualization uses `d3.area` with `curveBasis` for the smooth path, `d3.scaleTime` and `d3.scaleLinear` for scaling, and `d3.axisLeft` and `d3.axisBottom` for the axes, rendering to SVG. Data is loaded from a CSV file on VizHub.
