This line chart displays one week of hourly temperature data in San Francisco, sourced from Data Canvas - Sense Your City. 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` for the smoothed temperature curve. The gold-colored line shows temperature fluctuations over time, with gridlines and labeled axes for time and temperature in degrees Celsius.
