This scatter plot visualizes temperature changes in San Francisco over a week, using time on the x-axis and temperature on the y-axis. The visualization combines circles for individual data points with a smoothed line path generated via d3.line and curveBasis. It uses d3.scaleTime and d3.scaleLinear for scaling, with d3.axisBottom and d3.axisLeft for labeled axes. Data comes from a CSV file loaded using d3.csv, rendered as SVG with a margin-based layout.
