This visualization displays car sales data from 2013 to 2021, using a line chart to show the trend in total sales over time. The x-axis represents years, while the y-axis shows total sales figures. The chart is rendered as an SVG using D3 v5, with scales including `scaleTime` and `scaleLinear`, and axes created via `axisBottom` and `axisLeft`. The line is drawn using the `line` generator, and the data is loaded from a CSV file hosted on GitHub, with dates parsed using `d3.timeParse`.
