This scatter plot visualizes a week of temperature and time data in San Francisco, with orange circles marking each hourly reading. The time and temperature axes use D3’s `scaleTime` and `scaleLinear`, with gridlines drawn by `axisBottom` and `axisLeft`. The chart reads from a CSV file, parses timestamps and numeric temperatures, and renders the result as SVG circles. Axis labels and a title are appended via D3 selections, while CSS styles the text and tick marks.
