This scatter plot visualizes temperature readings over a week from the Sense Your City dataset, with time on the x-axis and temperature on the y-axis. Each point represents a timestamped measurement, and hovering reveals the exact time via a native SVG `<title>` tooltip. The React-based implementation uses D3 v5 scales (`scaleTime`, `scaleLinear`) and `extent` to map data to coordinates, while custom axis components render tick marks and labels. The SVG circles are generated by a Marks component, and data loading relies on D3’s `csv` parser fetching from a GitHub gist.
