This fork-area chart displays the number of Apple users over time, with a purple filled area beneath a smooth curve. The visualization uses D3 v6 with SVG rendering, employing `scaleTime`, `scaleLinear`, `area`, and `curveBasis` to generate the path. Data is loaded via `csv` from a remote dataset, with dates parsed using `timeParse`. Axes are customized with tick formatting and labels, and the chart includes a titled layout with margins, gridlines, and rotated axis text.
