This scatter plot displays a week of temperature readings in San Francisco, with time on the x-axis and temperature on the y-axis. Each circle represents a single measurement, showing how temperatures fluctuate across the day. The visualization uses D3 v5 with SVG rendering, employing `scaleTime` and `scaleLinear` for axes, `extent` for domains, and `axisBottom`/`axisLeft` for ticks. Data is loaded as CSV from VizHub and parsed, with circles drawn via `g.selectAll('circle').data(data).enter()` and styled with steelblue fill.
