This interactive parallel coordinates plot visualizes the classic Iris dataset, showing the relationships between sepal and petal measurements across three flower species. The code uses D3.js (v3) to render an SVG chart with lines colored by species (setosa, versicolor, virginica) via an ordinal color scale. Users can drag axis labels to reorder dimensions, dynamically rearranging the lines and transitions. The visualization includes a legend, background lines for context, and brushing functionality for each axis, demonstrating multidimensional data exploration in a React framework.
