This scatter plot displays a week of temperature readings in San Francisco, with time on the x-axis and temperature on the y-axis, using a blue dot for each recorded observation. The visualization is built with D3 v5, employing `scaleTime` and `scaleLinear` for axes, and `axisBottom` and `axisLeft` to generate gridlines and labels. Data is loaded as CSV from a Vizhub dataset, parsed with `new Date()` and `+d.temperature`, and rendered as SVG circles within a margin-based layout.
