This line chart displays pupil diameter over time, measured from the right eye, with the y-axis fixed from 0 to 7 millimeters. The visualization filters the dataset to the first eleven data points and renders them as a smooth, navy blue curve. The code uses D3 v5 with `scaleLinear`, `axisBottom`, `axisLeft`, and a `line` generator with `curveBasis` for the path, drawing to an SVG canvas. Data originates from a CSV file loaded via `d3.csv` and is normalized by converting timestamps into minutes.
