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. The data comes from the Data Canvas - Sense Your City project. Using d3.csv, d3.scaleTime, d3.scaleLinear, and d3.axisLeft/axisBottom, the code renders circles in SVG with a steelblue fill, clear axis labels, and a title. The axes include tick lines that extend across the chart for readability.
