A line chart visualizes Tesla sales in the USA from January 2021 to February 2022, with months on the x-axis and sales figures in thousands on the y-axis. The chart is built with React and D3 v7, using `scaleTime` and `scaleLinear` for axes and `line().curve(curveBasis)` for the smooth path. Data is loaded from a CSV via `d3.csv`, and the SVG rendering includes custom tick marks and axis labels styled with black text and maroon titles.
