This visualization displays a line chart of store sales versus profit, with profit on the x-axis (treated as time) and sales on the y-axis. The line path is drawn in red using d3.line, while d3.scaleTime and d3.scaleLinear handle the axes, which are rendered with axisBottom and axisLeft. The SVG is 960 by 500 pixels, and the data is loaded as CSV from a GitHub gist, with the chart titled "Storesales profit."
