This fork of an area chart displays UK population growth from 2010 to 2023, with annual values loaded from a CSV file. The visualization uses D3 v5’s `scaleLinear` and `scaleTime` for axes, `line` and `area` generators with a `curveBasis` smoothing, and renders to SVG. The chart includes labeled axes, gridlines, and a styled area fill, with population values formatted using D3’s `format` function.
