This parallel coordinates plot visualizes mental health metrics, including Anxiety, Depression, and Sleeplessness, with lines colored by gender (steelblue for males, hotpink for females). The code uses D3 v7’s `d3.csv` to load student data, `d3.scaleLinear` and `d3.scalePoint` to map dimensions, and `d3.line` to generate paths. Axes are added via `d3.axisLeft`, and hovering highlights individual lines by increasing opacity and stroke width.
