This interactive scatterplot allows users to explore the Iris flower dataset, comparing measurements like sepal and petal length and width, and species. The visualization uses D3.js to create an SVG plot with automatically scaled axes, supporting both quantitative and categorical variables. Users can change the x and y axes via dropdown menus, triggering smooth transitions of the data points. The iris data is loaded from a remote CSV file, and the plot updates with a 600ms transition and staggered delays for each circle.
