This example presents an interactive parallel coordinate plot of the classic Iris dataset, allowing users to reorder the dimensions by dragging the axis labels. The visualization renders each flower as a polyline connecting its measurements across the four numeric axes and the categorical species axis, with the three iris species distinguished by color. Built with D3 v7, the chart uses `d3.scaleLinear` and `d3.scaleBand` for axis scaling and `d3.line` to generate the paths. The reordering functionality relies on the Sortable.js library, which triggers a full re-render of the SVG when the drag operation ends.
