This scatter plot displays daily temperature readings in San Francisco over time, with time on the x-axis and temperature on the y-axis. The visualization uses D3 v5 to load CSV data, create a time scale with `scaleTime`, and a linear scale with `scaleLinear`. SVG circles represent individual data points, while axes with gridlines are generated using `axisBottom` and `axisLeft`. The chart includes labeled axes and a title, with styling applied via external CSS.
