This line chart visualizes car sales in India from 2009 to 2019, with the x-axis representing time and the y-axis showing sales volume. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` generators to render the SVG path, with grid lines styled via `.tick line`. Data is loaded as CSV from a GitHub gist and parsed using `d3.timeParse`. The chart includes labeled axes and a styled red line, with formatting applied to tick values.
