This visualization shows the relationships between four measurements from the Iris dataset using a parallel coordinates plot, where each flower is represented as a polyline crossing four vertical axes. The plot uses D3 v7’s `scaleLinear` for each dimension and `scalePoint` for axis positioning, with the axes labeled sepal length, sepal width, petal length, and petal width. Data is loaded from a CSV file and parsed into numeric values before being rendered as an SVG with semi-transparent circles at each data point.
