A temperature scatterplot shows hourly temperature readings over one week, with time on the x-axis and degrees on the y-axis. Each data point is an SVG circle colored teal, with a native `<title>` tooltip displaying the exact temperature value. The chart uses React components for the axes and marks, while D3 v6 APIs (`scaleTime`, `scaleLinear`, `extent`, `csv`) handle data loading, scaling, and tick generation. The dataset comes from the Sense Your City weather CSV, and labels are formatted with `timeFormat`.
