This interactive parallel coordinates plot visualizes the Iris flower dataset, displaying four numeric attributes (sepal length, sepal width, petal length, and petal width) as polylines colored by species—setosa, versicolor, and virginica—using a categorical color scale. Users can drag axes to reorder dimensions and use brush interactions on each axis to filter the displayed lines. Built with D3 v3, the SVG rendering uses d3.svg.line, d3.svg.axis, d3.svg.brush, and d3.behavior.drag for manipulation. The data is loaded as CSV from a GitHub repository, with axis labels and a color legend included.
