This visualization shows temperature readings in San Francisco over one week, plotting each measurement as a circular point along a time-based x-axis and a linear temperature y-axis. The chart includes labeled axes for time and temperature, with a title displayed above the plot. The code uses D3 v6 methods such as `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to construct the scales and axes, and renders the data as SVG circles. The data comes from a CSV file loaded via D3’s `csv` function, with timestamps parsed as dates.
