Temperature in San Francisco Line Chart
This line chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas - Sense Your City, with a smooth curve tracking readings over time. The SVG rendering uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to generate the path. Grid lines and labeled axes for time and temperature support the visualization, while the data is loaded via `d3.csv` and parsed into JavaScript `Date` objects.
