This line chart visualizes one week of temperature data in San Francisco, sourced from the Data Canvas - Sense Your City project. It uses time on the x-axis and temperature on the y-axis, with a smooth curved line drawn using d3.line and curveBasis. The chart is rendered as SVG, with axes created via d3.axisBottom and d3.axisLeft. Data is loaded from a CSV file, parsed, and scaled using d3.scaleTime and d3.scaleLinear.
