This scatter plot displays hourly temperature readings in San Francisco, with each circle representing a single measurement colored on a blue-to-red gradient. The visualization uses d3.scaleTime and d3.scaleLinear to map timestamps and temperatures to axes, while d3.scaleSequential with interpolateRdBu applies the color encoding. Data loads from a CSV file and renders as SVG circles with opacity and stroke styling. Both axes include descriptive labels, and the chart includes a title showing the temperature data spans throughout the day.
