This line chart visualizes temperature over time using data from the Data Canvas Sense Your City Dataset. Rendered with React and SVG, it uses D3 v5's `scaleTime`, `scaleLinear`, `extent`, and `line` with `curveNatural` to plot a smoothed path and circular points. The chart includes labeled axes with tick marks formatted via `timeFormat('%a')`, and hovering over a point reveals its timestamp.
