Line Chart - from Working with Time
This line chart visualizes temperature readings over one week from the Data Canvas Sense Your City dataset, depicting time on the x-axis and temperature on the y-axis. The SVG visualization, built with React and D3 v5, uses `scaleTime` and `scaleLinear` for axes, and draws the line with `line().curve(curveNatural)` while rendering data points as circles with tooltips showing the timestamp. Styled with the Poppins font and teal marks, the example demonstrates natural curve interpolation for time-series data.
