This scatter plot displays hourly temperature readings in San Francisco over a week, using a blue circle per data point positioned by time on the x-axis and temperature on the y-axis. The visualization uses D3 v5 with an SVG rendering, employing d3.scaleTime and d3.scaleLinear for axes, d3.axisBottom and d3.axisLeft for tick marks, and d3.csv to load the timestamp-temperature pairs from the included CSV file.
