This area chart visualizes one week of temperature data in San Francisco, with timestamps on the x-axis and degrees Celsius on the y-axis. The SVG rendering uses d3.scaleTime and d3.scaleLinear to map data to coordinates, while d3.area with curveBasis generates the filled path that highlights temperature fluctuations. Axis labels and a title are added via d3.axisBottom and d3.axisLeft, with data sourced from the Data Canvas - Sense Your City project.
