This scatter plot visualizes one week of temperature data in San Francisco, mapping time on the x-axis and temperature on the y-axis. The visualization uses D3 v5 with SVG rendering, employing `scaleTime` and `scaleLinear` for the axes, `extent` to compute domains, and `axisBottom` and `axisLeft` for ticks. Data is loaded from a CSV file via `d3.csv`, with timestamps parsed as `Date` objects and temperatures converted to numbers. The chart includes labeled axes, a title, and semi-transparent blue circles for each temperature reading.
