This example visualizes temperature trends over time as a smooth line chart. The visualization uses the Data Canvas Sense Your City dataset, plotting timestamp against temperature with a natural cubic spline curve to connect data points. Built with React and D3.v5, the code leverages D3's `scaleTime`, `scaleLinear`, and `line` APIs to construct the axes and path, while SVG renders the final output. The chart is styled with a Poppins font and a teal color scheme, with axis ticks and labels formatted for clarity.
