This example visualizes weekly temperature data as a smooth, curved line chart rendered with SVG. The chart uses D3’s `scaleTime`, `scaleLinear`, and `curveNatural` to create a stylized path, while React components handle the axes and marks. Data is loaded from a CSV file via D3’s `csv` method. The visualization includes custom axis labels, a Poppins font, and muted teal and gray styling defined in CSS, with tick formatting using `timeFormat`.
