This scatter plot visualizes the Iris dataset, mapping petal width to sepal length while color- and shape-encoding species. Built with reusable D3 chart patterns, it uses `scaleOrdinal` and `symbol` for categorical encoding. Every two seconds, the animation cycles the x-axis through different numeric columns. The chart renders as SVG with `axisLeft` and `axisBottom` scales, and a custom legend distinguishes Setosa, virginica, and versicolor.
