This area chart shows motorcycle sales in India from 2012 to 2022, highlighting the trend of sales volume over time. The visualization uses D3.js v5 to render an SVG with both a line path and an area fill beneath it, employing `d3.line`, `d3.area`, and `curveBasis` for smoothing. Data is loaded from a CSV file and parsed with `d3.csv` and `d3.timeParse`, with axes generated via `axisBottom` and `axisLeft`.
