This fork of D3 v5 line chart visualizes one week of temperature data in San Francisco, sourced from Data Canvas's Sense Your City dataset. The SVG rendering plots temperature over time using `scaleTime` and `scaleLinear` axes, with `axisLeft` and `axisBottom` for ticks and labels. A `line` generator with `curveBasis` draws the smoothed temperature path, while styled circles and axis-label text are configured via CSS classes.
