This interactive parallel coordinate plot visualizes the Iris dataset, showing four flower measurements across vertical axes colored by species. Hovering a line highlights all lines of that species while dimming others, using D3 v4’s scaleOrdinal for colors and path generation via d3.line. Users can drag axis labels to reorder dimensions, with d3.drag updating axis positions and adjusting the x-scale point mapping. The SVG renders 149 data rows from iris.csv, excluding one duplicate, with axes built using d3.axisLeft.
