This chart visualizes temperature readings from San Francisco over time using an area fill beneath a smoothed curve. Temperature is plotted on the y-axis against timestamps on the x-axis, with the area colored orange and labeled axes for clarity. The visualization is rendered with SVG using D3 v5, leveraging `scaleTime` and `scaleLinear` for scaling, `area` with `curveBasis` for the smoothed area path, and `axisBottom`/`axisLeft` for the ticks. The data is loaded from a CSV file, with numeric temperature values and parsed dates.
