A scatter plot displays temperature readings over the course of a week, with each point representing a measurement. The visualization uses a time-scaled x-axis and linear y-axis, with weekday labels on the x-axis. Built with React and D3 v5, the code loads CSV data from the Data Canvas Sense Your City dataset, uses `scaleTime` and `scaleLinear` for axes, and renders SVG circles that include tooltips showing the time of each reading.
