This line chart displays one week of temperature data in San Francisco, sourced from the Data Canvas - Sense Your City project. The visualization uses D3 v7 with SVG rendering, employing `scaleTime` and `scaleLinear` for axes, `line` with `curveBasis` for the smoothed path, and circles for individual data points. The chart includes custom margins, gridlines via `tickSize`, and clear axis labels, with styling applied through external CSS.
