This line chart displays one week of temperature data in San Francisco, using a smooth curved line to show temperature fluctuations over time. The visualization uses D3 v5's `scaleTime` and `scaleLinear` for the axes, `line` with `curveBasis` for the path, and `axisBottom` and `axisLeft` for labeled ticks. Data comes from the Data Canvas - Sense Your City project, loaded via `csv` and parsed into `Date` and numeric values. The SVG render includes a maroon stroke path, grid lines, and axis titles for time and temperature.
