This interactive scatter plot visualizes the Iris dataset, mapping petal width against sepal length and using different symbols and colors to distinguish the three species. Built with a reusable D3 chart function, it employs `scaleLinear` for axes, `scaleOrdinal` for categorical symbol and color mappings, and SVG rendering. A legend identifies species, while an animation cycles through different x-axis variables every two seconds, dynamically updating the plot via the chart's accessor methods.
