This line chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City. The chart plots temperature in degrees Celsius on the y-axis against time on the x-axis, with a smooth curved line connecting data points. The visualization is rendered as SVG using D3 v5, employing APIs such as `scaleTime`, `scaleLinear`, `axisLeft`, `axisBottom`, `line`, and `curveBasis` to construct the axes and path. Interactive components are absent, with the focus on clear presentation of the temperature trend.
