This parallel coordinate plot visualizes the classic Iris dataset, displaying four morphological measurements for three flower species. Each observation appears as a semi-transparent polyline crossing the vertical axes, with color encoding the species classification via a categorical color scale. The visualization supports interactive reordering by dragging axis headers, which triggers animated transitions repositioning the axes. Built with D3 v5, the implementation uses `d3.scaleLinear` for value mapping, `d3.scaleOrdinal` for color assignment, and `d3.line` for generating the polylines from the CSV data.
