This line graph displays car sales from 2010 to 2020, with years on the x-axis and sales on the y-axis. The visualization uses React with D3 v5 APIs such as `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` to generate an SVG chart. Data is loaded from a CSV file hosted on GitHub, and rendered with styled axes, a red line path, and a title. The chart includes labeled axes and gridlines via tick sizes.
