This visualization displays weekly temperature measurements from San Francisco using a stylized line chart rendered as an SVG. The chart features a natural curve connecting data points across time, with labeled axes for temperature and time. Built with React and D3 v5, the code uses `scaleTime` and `scaleLinear` for scaling, `line()` with `curveNatural` for the path, and `csv` to load the dataset. The Poppins font and custom styling give the chart a modern, polished appearance.
