This visualization shows a week of temperature readings in San Francisco as a filled area chart. The area spans from the baseline to the temperature values over time, using D3 v6’s `scaleTime`, `scaleLinear`, `area`, and `curveBasis` to create the smooth shaded shape. The SVG rendering includes axis labels, a title, and grid lines via `axisBottom` and `axisLeft`. Data is loaded from a CSV file hosted on VizHub, with timestamps converted to JavaScript `Date` objects and temperatures parsed as numbers.
