This example plots temperature readings over time from the San Francisco week temperature dataset, rendered as a smooth natural curve through the data points. The visualization uses React with D3 v7, employing `scaleTime` and `scaleLinear` for the axes, `line()` with `curveNatural` for the path, and custom React components for the axes and marks. The SVG output includes interactive hover titles on each circle, though the circles remain commented out, and the chart supports labels for both time and temperature dimensions.
