This line chart visualizes annual car sales in India from 2009 to 2019, using time-scaled X-axis years and a linear Y-axis for sales figures, with a single red path marking the trend. The code selects an SVG, parses CSV data via d3.csv, and applies d3.scaleTime and d3.scaleLinear for axes, while d3.axisBottom and d3.axisLeft generate gridlines and labels. The line is rendered with d3.line, and data parsing uses d3.timeParse to convert date strings, with axis tick formatting applied through a custom number formatter.
