This line chart visualizes one week of temperature in San Francisco, with time on the x-axis and temperature in Celsius on the y-axis. The SVG rendering uses d3.scaleTime, d3.scaleLinear, d3.axisLeft, d3.axisBottom, and d3.line with a curveBasis smoothing generator. Data is loaded via d3.csv from a remote dataset, and each temperature value is parsed as a number while timestamps are converted to Date objects. The chart includes axis labels, a title, grid lines, and a maroon smoothed line path. Data originates from the Data Canvas - Sense Your City initiative.
