A scatter plot displays temperature readings over a week in San Francisco, with time on the x-axis and temperature on the y-axis. Using D3 v5, the visualization employs `scaleTime` and `scaleLinear` to map data, `axisBottom` and `axisLeft` for labeled axes with grid lines, and SVG circles for points. Data is loaded from a remote CSV via `csv`, with timestamps parsed as dates. Axis labels and a title are added through SVG text elements, styled via CSS.
