This visualization displays temperature variations over time for San Francisco, drawing from a week's worth of data from the Sense Your City dataset. The chart uses a smooth, stylized line to represent the temperature trend, with a natural curve applied via D3's `curveNatural` function, giving the path an organic, flowing appearance. Rendered in SVG within a React framework, the code leverages D3 v5's `scaleTime`, `scaleLinear`, and `extent` APIs to map data to axes, while the `AxisBottom` and `AxisLeft` components handle tick marks and labels. Styling is managed through CSS with the Poppins font, and a custom `Marks` component draws the data path.
