This line chart displays one week of temperature in San Francisco, using data from Data Canvas - Sense Your City. It visualizes temperature variations over time with a filled area beneath the line, rendered as SVG. The visualization uses d3.scaleTime, d3.scaleLinear, d3.area with curveBasis, and axes from d3.axisBottom and d3.axisLeft. Data is loaded as CSV and parsed with dates and numeric temperatures before rendering.
