This interactive scatter plot visualizes the Iris dataset, showing relationships between flower attributes as the x-axis cycles through petal width, sepal width, petal length, and sepal length every two seconds. Each species is distinguished by both color and symbol shape, with a legend displaying the mappings. Built with D3 v6, the reusable chart uses `scaleLinear`, `scaleOrdinal`, `symbol`, `axisBottom`, and `axisLeft` to render SVG marks and axes. The visible example originates from Curran’s gist and animates via `setInterval`, triggering re-renders of the chart.
