A scatter plot displays temperature readings recorded throughout a week in San Francisco, with time on the x-axis and temperature on the y-axis. Purple circles represent individual data points, while grid lines and labeled axes clarify the scale. The visualization uses D3 v5 with SVG rendering, employing `scaleTime`, `scaleLinear`, `extent`, and `axisBottom`/`axisLeft` to map data from a CSV file. Axis labels and a title are added directly to the SVG group.
