This animated scatter plot visualizes the iris dataset, cycling through different flower measurements (petal width, sepal width, petal length, sepal length) on the x-axis while keeping sepal length on the y-axis. Colored circles represent species categories (setosa, versicolor, virginica) with a static legend. The visualization uses D3.js’s `scaleLinear`, `axisLeft`, and `axisBottom` APIs to construct a reusable scatter plot, with a `setInterval` driving the animation. Data is loaded from a remote CSV file, rendered as SVG, and styled with custom labels and a title.
