This line chart displays one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City. It shows temperature fluctuations over time with time on the x-axis and temperature in degrees Celsius on the y-axis. The visualization uses d3.scaleTime and d3.scaleLinear for scaling, d3.line with curveBasis for the smoothed path, and d3.axisBottom and d3.axisLeft for the axes. The chart is rendered as an SVG with a maroon line and includes axis labels and a title.
