This line chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City. It plots temperature in degrees Celsius against time, with a smooth curved line generated using d3.line and curveBasis. The visualization uses d3.scaleTime and d3.scaleLinear for axes, rendered as SVG elements with gridlines and labeled axes. Data is loaded as CSV and parsed into Date and numeric values before rendering.
