This line chart visualizes temperature in San Francisco over time, with a smooth curved line connecting data points and labeled axes for Time and Temperature. The visualization uses D3 v5’s `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` with `curveBasis` to render the SVG path. Data is loaded from a CSV file via `d3.csv`, with timestamps parsed as dates and temperatures as numbers. The chart includes a title, tick marks, and a styled line with a steel-blue stroke.
