This scatter plot visualizes temperature in San Francisco over time, with each circle representing a temperature reading. The data is loaded from a CSV file, parsed, and rendered as an SVG using D3 v6. The code uses `d3.scaleLinear`, `d3.extent`, `d3.axisLeft`, and `d3.axisBottom` to map time and temperature values to coordinates, with axes showing tick marks, labels, and a titled chart. Circles are semi-transparent steel blue, and the margin-based layout positions the plot within a 960x500 SVG canvas.
