This scatter plot displays temperature readings in San Francisco over time, with each circle representing a data point. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to map timestamps and temperatures, rendering circles as SVG elements. Hovering highlights individual points by changing their fill color, while gridlines and labeled axes clarify the relationship between time and temperature. Data is loaded as CSV from an external dataset.
