This fork of ICE 7 Area Chart visualizes car sales in India from 2009 to 2019, using a smooth curve to show the sales trend over time. The chart combines a black line and an orange filled area beneath it, with labeled axes for year and sales. The code loads CSV data via `d3.csv` and renders an SVG using D3 v5, employing `scaleTime`, `scaleLinear`, `line` and `area` generators with `curveBasis` for smoothing. Axis labels are styled with CSS classes.
