This scatter plot visualizes the Iris dataset, showing petal width against sepal length, with each species color-coded (setosa in gold, versicolor in teal, and virginica in red). The visualization cycles through four attribute combinations every two seconds, updating both the axes and circle positions. Built with D3 v6, it uses `d3.scaleLinear`, `d3.scaleOrdinal`, `d3.axisLeft`, and `d3.axisBottom` within a reusable `scatterPlot` function, rendering as SVG circles with HTML labels.
