This visualization shows a week of temperature readings in San Francisco as a smooth, filled area chart over time. The area path is generated using D3’s `area` generator with a `curveBasis` interpolation, while `scaleTime` and `scaleLinear` map the timestamp and temperature data to the SVG canvas. Axes with gridlines are created via `axisBottom` and `axisLeft`, and the data is loaded as CSV from a VizHub-hosted dataset.
