This line chart visualizes temperature variations over the course of a week in San Francisco, with data loaded from a CSV file. The y-axis is labeled "Temperature" and the x-axis is labeled "Time," with both axes configured using `axisLeft` and `axisBottom`. The chart is rendered as an SVG, with a smooth, curved line generated using the `line` and `curveBasis` functions from D3 v5, and a maroon stroke styled via CSS.
