This interactive parallel coordinate plot visualizes the Iris flower dataset, showing the relationships between numerical measurements (sepal width, sepal length, petal width, petal length) across three species. Each flower is represented as a polyline colored by species (setosa, versicolor, virginica) using an ordinal color scale, with a legend indicating the categories. Built with D3 v3, the visualization uses `d3.svg.axis` and `d3.svg.line` for rendering SVG, and supports axis dragging via `d3.behavior.drag` to reorder dimensions, while the background context lines fade during interaction. The data is loaded from an external CSV file.
