This area chart displays one week of temperature data in San Francisco, sourced from Data Canvas: Sense Your City, with time on the x-axis and degrees Celsius on the y-axis. The visualization uses D3 version 5, employing `scaleTime` and `scaleLinear` for axes, a basis-smoothed `area` generator for the filled region, and `axisBottom` and `axisLeft` for gridlines and labels. The SVG render includes a title and axis annotations, with all styling handled by an external stylesheet.
