This scatter plot displays temperature readings over time for San Francisco, with each circle representing a data point. The visualization uses d3.scaleTime and d3.scaleLinear to map timestamps and temperatures to positions, while d3.axisLeft and d3.axisBottom generate the labeled axes with grid lines. Data is loaded as CSV via d3.csv and converted to Date and numeric types before rendering as semi-transparent steelblue circles. The chart includes custom axis labels and a title, all drawn as SVG elements within a fixed-width container.
