Fork of Parallel Coordinates with Brushing
This interactive parallel coordinates plot visualizes the Iris dataset, encoding each flower's measurements across four quantitative axes and one categorical axis. Users can brush along any axis to filter the displayed lines, with multiple brush interactions compositing to refine the multidimensional selection. The visualization uses D3.js for scales, line generation, axes, and color mapping, while the `d3-rosetta` library handles declarative SVG construction and transition-based animations. Brushed intervals trigger live updates to the filtered data, and path opacity animates smoothly during transitions.
