This example visualizes car sales in India from 2009 to 2019 using a line chart rendered with D3 v5 and SVG. The chart plots annual sales data on a time-scaled x-axis and a linear y-axis, with grid lines and axis labels for clarity. The code uses `d3.csv` to load the dataset, `d3.scaleTime` and `d3.scaleLinear` for scaling, `d3.line` to generate the path, and `d3.axisBottom` and `d3.axisLeft` to render axes.
