This area chart displays car sales in India from 2009 to 2019, with a smooth curve and orange filled area beneath the line to emphasize sales trends over time. The visualization uses d3.csv to load the data, d3.scaleTime and d3.scaleLinear for axes, and d3.area with d3.curveBasis to generate the filled path. The SVG is rendered with margin-based positioning, and axes are styled using d3.axisBottom and d3.axisLeft with custom tick formatting.
