This scatter plot shows the temperature in San Francisco over a week, with time on the x-axis and temperature on the y-axis. Each data point is represented as a steelblue circle, and the chart includes labeled axes and a title. The visualization uses d3.scaleTime and d3.scaleLinear for the axes, with d3.axisLeft and d3.axisBottom to render the ticks and grid lines. The data is loaded from a CSV file at a VizHub URL.
