This area chart displays a week of temperature data in San Francisco, using time on the x-axis and temperature on the y-axis. The data is loaded from a CSV file hosted on VizHub. The visualization is rendered as an SVG using D3 v5, employing the `area` function with a basis curve to create a smooth filled region, with axes generated by `axisBottom` and `axisLeft`. The chart is styled with a maroon fill and stroke, and includes axis labels and a title.
