This area chart visualizes perfume sales over time, using a smooth curve to connect annual data points and a green filled region beneath the line to emphasize sales volume. The chart includes labeled axes for Year and Sales, with gridlines and formatted tick values. Built with React and D3 v5, the code uses `scaleTime`, `scaleLinear`, `line`, `area`, and `curveBasis` to generate the SVG paths, while `axisLeft` and `axisBottom` add the scales. Data is loaded from a CSV file using `d3.csv` and parsed with `d3.timeParse`.
