This scatter plot shows a week of hourly temperature readings in San Francisco, with time on the x-axis and temperature on the y-axis, using blue circles to mark each observation. The chart is rendered as an SVG using D3 v5, with scales created via `scaleTime` for the temporal axis and `scaleLinear` for temperature. Data is loaded from a CSV file and parsed with `csv`, while the axes are generated using `axisBottom` and `axisLeft`, complete with labeled tick lines and a title.
