This line chart visualizes yearly sales data from a remote CSV file, mapping time on the x-axis and sales values on the y-axis. The code uses D3 v7’s `d3.csv` to load and parse data, `d3.scaleTime` and `d3.scaleLinear` for scales, and `d3.line` to generate a steelblue path. Axes are rendered with `d3.axisBottom` and `d3.axisLeft`, with custom formatting for years, and the SVG output is sized 800 by 400 pixels. The visualization demonstrates a clean, minimal line chart with labeled axes and no interactivity.
