This scatter plot visualizes temperature readings over time, with each circle representing a measurement plotted along a time-based x-axis and a linear temperature y-axis. Built with React and D3 v5, the visualization uses `scaleTime` and `scaleLinear` to map data from a CSV file into SVG circles. The chart includes labeled axes with formatted weekday tick marks on the x-axis, and hovering over a circle reveals the exact time through SVG `<title>` tooltips.
