This scatter plot visualizes one week of temperature data in San Francisco, with each circle representing a temperature reading plotted against time. The chart uses D3 v5’s `scaleTime` and `scaleLinear` to map the timestamp and temperature values, with axes rendered via `axisBottom` and `axisLeft`. Data is loaded as CSV from a VizHub dataset, parsed for numeric temperature and date objects, and drawn as SVG circles. Grid lines are created through tick sizes, and the visualization includes a title and axis labels.
