This scatter plot shows one week of temperature readings in San Francisco, with time on the x-axis and temperature in degrees Celsius on the y-axis. Each circle represents a single timestamped measurement, labeled across a titled "A Week in San Francisco" chart. Using D3 v5, the code loads CSV data, applies `scaleTime` and `scaleLinear` for axes, and renders SVG circles with a steelblue fill. Axis grids are drawn via `axisBottom` and `axisLeft` with removed domains, and the data originates from the Data Canvas - Sense Your City project.
