A scatter plot displays temperature readings over time, with each circle representing a single observation. The visualization uses React and D3 v7, leveraging `d3.scaleTime` and `d3.scaleLinear` for axes and `d3.csv` to load the Data Canvas Sense Your City dataset. SVG circles render the points, with hover tooltips showing the formatted time via `timeFormat`. The axis components are custom React functions, and the plot includes labeled axes for time and temperature.
