This line chart displays one week of temperature data in San Francisco, sourced from the Data Canvas - Sense Your City dataset. The visualization uses D3 v5 with an SVG rendering approach, employing `scaleTime` and `scaleLinear` for axes, `axisBottom` and `axisLeft` for ticks, and a `line` generator with `curveBasis` to smooth the temperature curve. Circles mark individual data points. The chart includes labeled axes for time and temperature, a title, and a styled maroon path with gridlines, all composed within a fixed-width SVG canvas.
