This scatter plot shows hourly temperature readings in San Francisco, with each circle colored along a blue-to-red sequential scale based on temperature value. The visualization uses d3.scaleTime and d3.scaleLinear for axes, d3.scaleSequential with interpolateRdBu for color encoding, and d3.axisBottom/axisLeft with formatted tick lines. Data loads from a CSV file containing timestamps and temperatures, while the SVG rendering includes labeled axes, a title, and circular marks with transparency and stroke styling.
