This line chart visualizes automobile sales in India from 1999 to 2012, with the x-axis representing years and the y-axis showing sales figures. The SVG rendering uses d3.scaleTime and d3.scaleLinear to map data, along with d3.axisBottom and d3.axisLeft for labeled axes. A d3.line generator creates the blue sales trend line, while the data is loaded asynchronously from a GitHub-hosted CSV file using d3.csv. The chart includes axis labels, a title, and grid lines, with styling applied via external CSS.
