This interactive parallel coordinates plot visualizes the Iris dataset, displaying four flower measurements (petal and sepal length/width) across three species. Built with React and D3.v4, it renders SVG paths with animated transitions that highlight a selected species while dimming others on hover. Color-coded legends map species to distinct hues, and the chart’s axes are adjustable via radio buttons, allowing users to reassign features to each dimension. The visualization uses `d3.scaleLinear` and `d3.scalePoint` for coordinate mapping and `d3.line()` to construct the polylines.
