This visualization displays Tesla sales data by year using a line chart. The chart plots yearly sales values on a linear scale against a time-based x-axis, with axis labels for “Year” and “Sales” and a title. The code loads CSV data from a GitHub gist and renders the line as an SVG path using D3 v5’s `scaleTime`, `scaleLinear`, `line` generator, `axisBottom`, and `axisLeft` functions within a React framework.
