This visualization displays a week of temperature readings in San Francisco as a smooth line chart over time. The line path is generated using D3’s `line()` generator with `curveBasis` to create a curved trend, while time and linear scales map the timestamp and temperature data. The chart includes labeled axes for Time and Temperature, with tick marks and gridlines rendered via `axisBottom` and `axisLeft`. The underlying data is loaded as a CSV from a dataset on temperature in San Francisco, parsed into date and numeric values, and rendered as an SVG within an 800 by 430 pixel viewport using D3 v5.
