This area chart visualizes the sales of cars in India from 2009 to 2019, using a smoothed line and orange filled area to show the trend over time. The visualization is rendered as an SVG using D3 v5, with the `scaleTime` and `scaleLinear` functions handling the axes, while `area()` and `line()` with `curveBasis` generate the smoothed shapes. Data is loaded from a CSV file hosted on GitHub, parsed with `d3.csv` and `d3.timeParse` to convert date strings. The chart includes labeled axes and grid lines with formatted tick marks.
