This line chart displays one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City. The visualization uses d3.csv to load the dataset, then renders a smooth curved line with d3.line and curveBasis. Time and temperature scales are created with d3.scaleTime and d3.scaleLinear, while d3.axisBottom and d3.axisLeft generate the axes. The chart includes labeled axes for Time and Temperature, grid lines via tickSize, and a title, all drawn as SVG elements within a 960x500 viewport.
