This interactive scatter plot displays the Iris dataset, encoding petal and sepal measurements for three flower species. The D3.js (v6.7.0) visualization cycles through four column combinations on the x-axis while the y-axis remains fixed, animating the points with each interval. A legend identifies species by color (green for setosa, orange for versicolor, blue for virginica). The implementation uses reusable scatter plot logic from `scatterPlot.js` with `scaleLinear`, `axisLeft`, and `axisBottom`, while `index.js` handles data parsing, marker styling, and dynamic axis updates.
