This line chart displays car sales in India from 2009 to 2019, using a time-scaled x-axis for years and a linear y-axis for sales volume. The visualization relies on D3 v5’s `scaleTime`, `scaleLinear`, `line`, and `axisBottom`/`axisLeft` APIs to generate SVG paths and gridlines. Data is loaded as CSV from a GitHub gist, with year values parsed via `d3.timeParse`. Styling uses CSS for axis labels, tick colors, and a prominent red line stroke, with margins positioning the chart within a 960x500 SVG canvas.
