This visualization displays the classic Iris dataset as a parallel coordinate plot, with each polyline representing one flower specimen across four measurements: sepal length, sepal width, petal length, and petal width. The three Iris species are distinguished by color, with semi-transparent strokes revealing density overlaps between classes. The implementation uses D3 v5's `scalePoint` and `scaleLinear` for axes, `d3.line` to generate paths, and `axisLeft` for tick marks. A legend with colored circles identifies each species, while the title and axis labels are rendered as SVG text elements. The data originates from a CSV file loaded via `d3.csv`.
