This scatter plot shows the relationship between time and temperature in San Francisco, with each circle representing a temperature reading. The visualization uses D3 v5’s `scaleLinear`, `axisBottom`, and `axisLeft` to map the time and temperature values onto an SVG canvas. The code loads data from a CSV file, parses the timestamp and temperature fields, and renders circles with semi-transparent steel-blue fills. The chart includes axis labels and a title, with grid lines generated via tick sizes.
