This example visualizes San Francisco temperature readings over a week using a smooth, stylized line chart. The React app loads CSV data via `useData` and renders the time series with D3’s `scaleTime` and `scaleLinear` axes, while the line path is generated using `d3.line` with a `curveNatural` interpolation. The SVG output omits data points, emphasizing the fluid curve, with axis ticks and labels styled via CSS classes from the bundled components.
