This line chart displays one week of temperature data for San Francisco, plotted as revenue values per year with time on the x-axis. The visualization uses d3.csv to load the data, then creates scales with scaleTime and scaleLinear, renders axes via axisBottom and axisLeft, and draws the smooth curve using d3.line with curveBasis. The SVG output includes styled axis labels and a title, with a maroon stroke for the line path. The data originates from the Data Canvas - Sense Your City project.
