This visualization shows weekly temperature trends in San Francisco as a filled area chart, with a smooth curve representing the data over time. The vertical axis measures temperature, while the horizontal axis displays time series data. The chart is rendered using D3 v6 in an SVG format, employing `scaleTime` and `scaleLinear` for axes, `area()` with `curveBasis` for the smooth path, and `axisBottom`/`axisLeft` for ticks. Data comes from a CSV file containing forest cover loss figures, though the code repurposes the date field as the time variable.
