Stylized Line Chart
A stylized line chart displays temperature readings over the course of a week from the Data Canvas Sense Your City dataset. The chart uses React to render SVG elements, with D3 v5 providing scales, axis generation, and the natural curve interpolation via `line().curve(curveNatural)`. The visualization omits data point circles, relying instead on a thick teal stroke and Poppins typography to create a clean, modern aesthetic.
