This area chart displays car sales in India from 2009 to 2019, with years on the x-axis and sales figures on the y-axis. The visualization combines a smooth black line for the trend and an orange area beneath it to emphasize magnitude. Built with D3 v5, it uses `scaleTime` and `scaleLinear` for axes, along with `line` and `area` generators with `curveBasis` for smoothing. Data is loaded from a CSV file via `d3.csv`.
