A scatter plot displays temperature readings across one week in San Francisco, with time on the x-axis and temperature on the y-axis. The SVG visualization uses d3.scaleTime and d3.scaleLinear to map data, d3.axisBottom and d3.axisLeft for labeled axes, and circles with steelblue fill for each data point. Data loads from a CSV file via d3.csv, and the chart includes a title and axis labels. Grid lines extend across the plot area, generated through tickSize on the axes.
