This parallel coordinate plot visualizes the Iris dataset, showing how measurements of sepal and petal length and width vary across three flower species. Each polyline represents a single iris, colored by its class, with axes for each attribute arranged horizontally. The visualization uses D3.js v5, employing `d3.scalePoint`, `d3.scaleLinear`, and `d3.axisLeft` to construct axes and SVG paths for the data lines. The dataset is loaded via `d3.csv`, and a legend maps class names to specific color values.
