This area chart displays the sales of cars in India from 2009 to 2019. The visualization combines a black line with a smoothed curve for the trend and an orange area fill below it, using a time-scaled x-axis and a linear y-axis. The chart is built with D3 v5, using `scaleTime`, `scaleLinear`, `axisLeft`, `axisBottom`, and the `line` and `area` generators with `curveBasis`. The data is loaded from a CSV file, with the year parsed via `d3.timeParse`.
