This interactive parallel coordinate plot visualizes the Iris dataset, showing the relationships between sepal length, sepal width, petal length, and petal width across three iris species, colored using an ordinal color scale. Users can drag the vertical axes to reorder dimensions, with the polylines and remaining axes smoothly transitioning to new positions via d3.drag and d3.transition. The visualization is built with D3 v7, using d3.scalePoint for axis placement and d3.scaleLinear for each trait’s y-axis, rendering semi-transparent SVG paths for each data record.
