This interactive parallel coordinate plot visualizes the classic Iris dataset, displaying four measured attributes for three flower species. Built with D3 v5, it renders each flower as a colored polyline across vertical axes, with colors distinguishing Iris setosa, versicolor, and virginica. Users can drag any y-axis label to reorder the axes, dynamically repositioning the corresponding coordinate lines. The implementation uses `d3.scaleLinear` and `d3.axisLeft` for axes, with `d3.drag()` handling the interactive reordering and `d3.transition()` animating the axis shifts.
