This area chart visualizes perfume sales over time, with a smooth curved line for the trend and a green shaded region beneath it. The chart uses D3 v5’s `scaleTime`, `scaleLinear`, `line`, `area`, and `curveBasis` to render the SVG paths, with axes from `axisBottom` and `axisLeft`. Data is loaded as CSV from a GitHub gist, parsed with `d3.timeParse`, and displayed with formatted axis ticks. The React framework is not used in the runtime code, which directly appends SVG elements.
