This line chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City. The chart displays a smooth, curved line plotting temperature over time, with labeled axes for time and temperature and a title. The visualization is rendered using D3 version 7, leveraging `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` for the smoothed path. The SVG output includes styled gridlines and text via CSS, with data loaded from a CSV file.
