This line chart displays product sales quantities over time from 2011 to 2020, with the x-axis representing the date sold and the y-axis showing quantity. The visualization uses D3 v5 to load CSV data, parse dates with `d3.timeParse`, and render the line via `d3.line` with SVG paths. Axes are generated using `d3.axisLeft` and `d3.axisBottom`, while scales (`d3.scaleTime`, `d3.scaleLinear`) map data to the plot area. A blue stroke line connects data points across the time span.
