This area chart visualizes yearly perfume sales from a CSV dataset, using a smooth curve to show the sales trend over time and a filled area beneath the line to emphasize magnitude. The SVG is rendered with D3 v5, using `scaleTime` for the year axis, `scaleLinear` for sales, and `line` and `area` generators with `curveBasis` for smoothing. Axes are drawn with `axisBottom` and `axisLeft`, and the data is loaded via `d3.csv` before parsing dates with `d3.timeParse`.
