This line chart visualizes one week of temperature data in San Francisco, sourced from the Data Canvas - Sense Your City project. It uses d3.scaleTime and d3.scaleLinear to map timestamps and temperature values, with d3.axisBottom and d3.axisLeft rendering labeled axes. The smooth line path is generated using d3.line with curveBasis. The SVG chart includes gridlines via tick marks, a title, and axis labels, with data loaded as CSV and parsed into Date and numeric values before rendering.
