A week of San Francisco temperatures is shown as a scatter plot of daily readings, with time on the x-axis and temperature on the y-axis, using green semi-transparent circles. The chart is rendered in SVG with D3 v5, employing `scaleTime`, `scaleLinear`, and `scalePoint` (the latter unused). Axes are drawn with `axisLeft` and `axisBottom`, including grid lines and rotated axis labels. Data is loaded via `d3.csv` from a remote CSV file, and each timestamp is parsed into a `Date` object before plotting.
