This line chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City. It shows temperature trends over time using smooth curves generated with the d3.line function and curveBasis interpolation. The visualization employs d3.scaleTime and d3.scaleLinear for axes, with d3.axisBottom and d3.axisLeft for tick rendering. Data is loaded via d3.csv, parsed into Date and numeric values, and rendered as an SVG path styled with a maroon stroke.
