This line chart visualizes a week of temperature data in San Francisco, showing the change over time with a smooth, filled area beneath the line. The x-axis represents time in hours, while the y-axis displays temperature values. The visualization is built with D3 v5, using `scaleTime` and `scaleLinear` for the axes, along with the `area` generator and `curveBasis` interpolation to create the shaded curve. Data is loaded from a CSV file hosted on VizHub and rendered as SVG.
