This area chart displays a week of temperature data for San Francisco, with time on the x-axis and temperature on the y-axis, using a smoothed, filled path to convey the trend. The visualization, built with D3 v5 and rendered as SVG, applies a basis curve to the area generator for a fluid line and fills the shape in maroon with transparency. A CSV file provides the data, loaded asynchronously, while axis tick marks extend across the plot for grid-like reference, and both axes are labeled. The title appears at the top, with styling handled via an external stylesheet.
