A line graph displays Amazon's daily closing stock price from late May through mid-August 2019, with dates on the x-axis and price on the y-axis. The line is drawn in steelblue with a 1.5-pixel stroke. The visualization uses D3 v6 APIs including `d3.timeParse`, `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.line` to process the CSV data and render the SVG path.
