A parallel coordinates chart displays the Iris flower dataset across four quantitative dimensions—petal length, petal width, sepal length, and sepal width—with each species colored via a `d3.scaleOrdinal` and the `schemeDark2` palette. The React component builds per-dimension linear scales with `d3.scaleLinear` and a common point scale for axis positioning, then renders natural curves through each row using the `d3.line` generator with `curveNatural` within an SVG. Data is loaded asynchronously from a CSV using `d3.csv` inside a custom `useData` hook.
