This scatter plot visualizes one week of temperature data in San Francisco, with time on the x-axis and temperature in degrees Celsius on the y-axis. The D3.js code uses `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `extent` to map the data, rendering red semi-transparent circles in an SVG. The data is loaded via `d3.csv` from a remote dataset, and axes include labeled titles with gridlines, while a main title appears above the plot.
