This area chart displays a week of hourly temperature readings in San Francisco, with a smooth orange gradient curve emphasizing the temperature range. The visualization uses D3 v5’s `area()` generator with `curveBasis` to create a filled path between the temperature values and the baseline, while `scaleTime` and `scaleLinear` map the temporal and temperature axes. Data is loaded from a CSV file hosted on VizHub, and axes are rendered with `axisBottom` and `axisLeft` onto an SVG canvas.
