This scatter plot shows temperature readings over time in San Francisco, with a red semi-transparent circle for each data point and an orange line connecting them in chronological sequence. The visualization uses D3 v5 with SVG rendering, employing `scaleTime` and `scaleLinear` for the axes, `axisBottom` and `axisLeft` for tick marks, and `line` to generate the path. Data is loaded as CSV from a remote source, with timestamps parsed as dates and temperatures converted to numbers before rendering.
