This area chart displays one week of temperature data in San Francisco, sourced from the Data Canvas – Sense Your City project. The chart uses a smoothed curve (`curveBasis`) to fill the area between the temperature line and the baseline, with time on the x-axis and degrees Celsius on the y-axis. The visualization is rendered as an SVG using D3 v6, with axes and gridlines generated via `axisBottom` and `axisLeft`, and the data is loaded from a CSV file using `csv`. The chart is styled with a maroon fill and includes labeled axes and a title.
