This scatterplot displays a week of temperature measurements in San Francisco, with time on the x-axis and temperature in degrees Celsius on the y-axis. The visualization uses d3.csv to load the data, then d3.scaleTime and d3.scaleLinear to map the values, with d3.axisBottom and d3.axisLeft rendering the labeled axes. Orange circles are positioned using the scales, and the chart includes a title and axis labels styled via CSS. The example originates from the Data Canvas - Sense Your City project.
