This visualization displays a week of San Francisco temperature data as a smooth time series line chart. The chart uses a React front end to render SVG elements, with D3 v5 providing the scales (`scaleTime`, `scaleLinear`) and the `line` and `curveNatural` generators for the path. Temperature readings from the CSV dataset are plotted against time on the x-axis, with formatted tick labels showing the day of the week. The code reveals the underlying data loading through `csv` and a custom `useData` hook that parses timestamps and numeric values.
