This scatter plot visualizes temperature measurements in San Francisco over time, with each circle representing a data point plotted along time and temperature axes. The chart uses D3 v5’s `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to construct the scales and axes, while circles are rendered in SVG. Data is loaded from a CSV file via `csv()` and parsed into dates and numeric temperatures. Axis labels and a title are added using SVG text elements, with customized tick sizes and styling defined in the accompanying stylesheet.
