This parallel coordinates plot visualizes the Iris dataset, enabling multidimensional filtering through brushing on each axis. The visualization uses D3 scales, line generators, and brushY interactions, with transitions that fade lines in and out as filters change. Color encoding distinguishes species via scaleOrdinal with a hue shift applied to the default scheme. The chart is responsive, adapting to container resizing through observeResize, and uses mix-blend-mode for overlapping line rendering.
