A line plot displays temperature readings in San Francisco over a week, with time on the x-axis and temperature on the y-axis. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` generators with `curveBasis` to render a smooth orange path. Data is loaded from a CSV via `csv`, and axes are styled with grid lines and labels, all drawn as SVG elements.
