This interactive scatterplot visualizes the Iris flower dataset, plotting sepal and petal measurements against each other. Users select the x and y axes from dropdown menus, and the points animate smoothly to their new positions with staggered transitions. The visualization encodes the three Iris species with red, green, and blue semi-transparent circles. Built with D3 v7, it uses `scaleLinear`, `axisBottom`, `axisLeft`, and `transition` to handle scaling, axes, and animated updates when the selected columns change.
