This scatter plot displays one week of temperature readings in San Francisco, with time on the x-axis and degrees Celsius on the y-axis. It uses d3.scaleTime and d3.scaleLinear to map the data, while d3.axisBottom and d3.axisLeft render the labeled axes with grid lines. The temperature data originates from the Data Canvas - Sense Your City dataset and is loaded via d3.csv. Each temperature observation is represented as a steelblue circle, and the visualization is rendered as SVG within a fixed 960 by 500 pixel viewport.
