This interactive parallel coordinate plot visualizes the Iris dataset, showing four measured attributes for three flower species. Users can reassign each of the four axes to different columns using dropdown menus, allowing exploration of relationships between variables. The visualization uses D3.js v5 with SVG rendering, employing `d3.scalePoint`, `d3.scaleLinear`, and `d3.line` to draw colored polylines for each sample. A legend identifies the species, and class-specific colors distinguish the three Iris varieties throughout the plot.
