This scatter plot visualizes hourly temperatures in San Francisco over time, with each circle representing a reading plotted by timestamp and temperature. The chart uses D3 v5’s `scaleLinear`, `axisBottom`, and `axisLeft` to construct the axes and scales, while circles are appended to an SVG with red fill and partial opacity. Data is loaded from a CSV via `csv`, with timestamps parsed into `Date` objects and temperatures converted to numbers. The visualization includes labeled axes and a title, rendered entirely with SVG elements.
