This chart visualizes temperature readings over the course of a week, sourced from a San Francisco dataset. A smooth line chart is rendered using D3’s natural curve interpolation. The visualization is built with React and D3 v5, utilizing `scaleTime` and `scaleLinear` for axes, `line()` and `curveNatural` for the path, and SVG elements for rendering. The interface loads data via `csv()` and includes interactive tooltips on data points. The chart features a minimal design with a custom Poppins font and muted color palette.
