This scatter plot visualizes a week of temperature readings in San Francisco, with time on the x-axis and temperature on the y-axis. Using D3 v5, the code employs `scaleTime` and `scaleLinear` for axes, `axisBottom` and `axisLeft` for ticks, and SVG circles to represent data points. The data is loaded via `csv` from a VizHub dataset, with timestamps parsed as `Date` objects. Styling includes orange circles, light green tick lines, and custom axis labels.
