This area chart shows bike sales in India from 2012 to 2022, using a time-scaled x-axis for years and a linear y-axis for sales volume. The visualization combines a black line path with a grey filled area beneath it, drawn using SVG via D3 v5’s `line()`, `area()`, and `curveBasis` generators. Data is loaded from a CSV file and parsed with `d3.timeParse`, while axes are created using `axisBottom` and `axisLeft` with custom tick formatting. The chart includes labeled axes and a rotated y-axis label.
