This interactive parallel coordinate plot visualizes the classic Iris dataset, showing how each flower’s sepal and petal measurements vary across three species. Users can drag any vertical axis horizontally to reorder the dimensions, with all connecting polylines smoothly updating via D3 transitions. The visualization uses D3 v5’s `scaleLinear`, `scaleOrdinal`, and `scalePoint` for positioning, while axes are rendered with `axisLeft` and drag behavior is implemented through `d3.drag()`. Data is loaded from a CSV file and plotted as semi-transparent SVG paths colored by species.
