A line chart displays a week of temperature readings in San Francisco, with time on the x-axis and temperature on the y-axis, using a smoothed curve to connect the data points. The visualization loads CSV data from a VizHub dataset, parsing timestamps and numeric temperatures before rendering. Built with D3 v5, it employs `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to generate the path. SVG output includes labeled axes, a title, and a maroon stroke styled via CSS.
