This time scatter plot visualizes temperature readings over time as red circles on an SVG canvas. The visualization uses D3's `scaleTime` and `scaleLinear` for axes mapping, with `timeFormat` to display weekday labels on the bottom axis. React renders each data point as a circle, with tooltips showing the formatted timestamp. The chart loads data from a CSV file via D3's `csv` utility, and custom React components handle axis and mark rendering.
