A scatter plot displays a week of temperature readings in San Francisco, with time on the x-axis and temperature on the y-axis. The chart uses d3.scaleTime and d3.scaleLinear to map the data, with d3.axisBottom and d3.axisLeft for labeled axes. Points are rendered as SVG circles with a steelblue fill, and axis labels and a title are added via SVG text elements. The data is loaded from a CSV file using d3.csv and parsed into date and numeric values.
