This visualization displays the classic Iris dataset as a parallel coordinate plot, with each flower sample drawn as a polyline connecting its sepal and petal measurements across four vertical axes. The lines are colored by species (setosa, versicolor, virginica) using a predefined color scale, and a legend identifies each class. The code uses D3 v5 APIs including `scalePoint`, `scaleLinear`, `axisLeft`, and `line` to position axes and render the paths as SVG elements, with data loaded via `d3.csv` from a remote GitHub source.
