This area chart visualizes a week of temperature readings in San Francisco, plotting temperature over time with a smooth, maroon-filled curve. The x-axis shows timestamps and the y-axis shows temperature, with labeled axes and a title. Built with D3 v5, the code uses `scaleTime`, `scaleLinear`, and the `area` generator with `curveBasis` to create the smooth path, while `axisBottom` and `axisLeft` render the tick marks. Data is loaded from a CSV file, and the SVG rendering approach is evident.
