This line chart visualizes temperature readings over time in San Francisco, showing how values fluctuate across the dataset’s timeline. The chart uses an SVG rendering approach with D3.js v5, employing `scaleTime` and `scaleLinear` for the axes, and `line` with `curveBasis` to create a smoothed path. Data is loaded via `csv` from a remote file, with timestamps parsed as dates and temperatures converted to numbers. The visualization includes labeled axes with tick marks, gridlines, and a title, while the line itself is styled in maroon for clarity.
