This scatter plot visualizes one week of temperature data in San Francisco, using D3 v6 to position circles on SVG canvas based on timestamp and temperature measurements. The chart includes labeled axes for time and temperature, with a title "A week in San Francisco" and uses grid lines and tick marks for readability. The data is loaded from an external CSV via D3's `csv` function, then mapped through `scaleTime` and `scaleLinear` scales, with axes generated using `axisBottom` and `axisLeft`.
