This visualization displays temperature readings over time for a week in San Francisco, using a smooth curved line to show the trend. The chart plots timestamps on the x-axis and temperature values on the y-axis, with the x-axis formatted to show abbreviated weekday labels. The visualization is built with React and D3 v6, using `scaleTime` and `scaleLinear` for the axes, and `line` with `curveNatural` to create the smoothed path connecting data points. The data is loaded from a CSV file using `d3.csv` and rendered as SVG.
