This scatter plot visualizes temperature readings over time from the Data Canvas Sense Your City dataset, showing the fluctuation of weekly temperatures. The visualization uses React with D3 v5 scales, including `scaleTime` and `scaleLinear`, to map data points as circles on an SVG canvas. Axes are rendered via custom React components, with `timeFormat` for date labels and a native SVG `<title>` element for hover tooltips. Data is loaded asynchronously using D3's `csv` method and processed through useState and useEffect hooks.
