This interactive parallel coordinate plot visualizes the Iris dataset, displaying four measurements—sepal length, sepal width, petal length, and petal width—as connected polylines for 149 samples, colored by species (red, green, blue). Users can drag any axis horizontally to reorder dimensions, which updates the line paths accordingly. Built with D3 v4, it uses `d3.scaleOrdinal` for color mapping, `d3.scalePoint` for axis positioning, `d3.axisLeft` for rendering ticks, and `d3.drag` for interactive reordering, with hover highlighting that dims non-selected lines via `transition()` styling.
