This scatterplot displays temperature readings in San Francisco over time, with each point representing a measurement plotted along a time-scaled x-axis and a linear temperature y-axis. The chart uses D3 v6’s `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to construct the axes, while data is loaded via `csv` from a remote dataset. Circular marks are rendered with SVG, styled in steel blue, and the chart includes labeled axes for clarity.
