This reusable scatter plot visualizes the Iris dataset, mapping petal width against sepal length with points colored and shaped by species—setosa, versicolor, and virginica. Built with D3 v6, it uses scaleLinear, scaleOrdinal, axisLeft, axisBottom, and symbol generators to render SVG marks. The axes dynamically cycle through different measurement columns every ten seconds via setInterval, updating the chart through a reusable closure-based chart function that returns getter and setter accessors.
