This line chart visualizes temperature measurements over time from the Data Canvas Sense Your City Dataset, showing a smooth curve with points that reveal a sinusoidal pattern typical of seasonal variation. The visualization uses React with D3 v7, employing `scaleTime` and `scaleLinear` for axes, `d3.line()` with `curveNatural` for the path, and `d3.csv` for data loading. SVG rendering includes dual axes, axis labels, and interactive circles with tooltips displaying the day of the week.
