This area chart visualizes the total sales of Rolex watches in India over a decade, with the x-axis representing the year and the y-axis showing total sales figures. The chart uses D3 v5 functions including `area` and `line` generators with `curveBasis` for smoothing, along with `scaleTime` and `scaleLinear` to map data to coordinates. The code also employs `axisBottom` and `axisLeft` for labeled axes, and imports data from a CSV file containing yearly sales records. The visualization is rendered as an SVG, with a semi-transparent steelblue area and a darkblue line overlay.
