A scatterplot displays a week of temperature readings in San Francisco, with time on the x-axis and temperature on the y-axis. The chart uses D3 v5 with SVG rendering, employing `scaleTime`, `scaleLinear`, and `axisBottom`/`axisLeft` for axes and gridlines. Data is loaded via `csv` from a remote dataset, with each timestamp parsed as a `Date` and temperatures as numbers. Circular marks are placed using `scaleTime` and `scaleLinear` mappings, with custom axis labels and a title styled via CSS.
