This scatter plot displays temperature readings over one week in San Francisco, with time on the x-axis and temperature on the y-axis. Using D3 v5, the code loads CSV data via `d3.csv`, parses timestamps and numeric values, and renders circles scaled with `d3.scaleTime` and `d3.scaleLinear`. Axes are generated with `d3.axisBottom` and `d3.axisLeft`, featuring grid lines and custom labels. The SVG output is styled with a clean, minimalist aesthetic, with steel-blue points highlighting the temperature trend across the week.
