This line chart visualizes automobile sales in India from 1999 to 2012, using d3.csv to load data from a GitHub gist and d3.scaleTime and d3.scaleLinear to map years and sales values. The SVG rendering uses d3.axisBottom and d3.axisLeft for labeled axes, while d3.line generates the path that represents the sales trend over time. The chart includes a title and axis labels styled via CSS.
