This stylized line chart visualizes San Francisco temperature data over a week, using a smooth natural curve to connect individual data points. The chart is rendered with React and D3 v5, using `scaleTime` and `scaleLinear` to map the temporal and temperature axes, while the `line`, `curveNatural`, and `extent` APIs generate the path. The SVG output uses a teal color scheme with circular markers that include tooltips for hourly timestamps, and the plot is framed by custom tick marks from the `AxisBottom` and `AxisLeft` components.
