This animated scatter plot cycles through pairs of Iris flower measurements, highlighting sepal length on the y-axis while rotating through petal width, sepal width, petal length, and sepal length on the x-axis. Circles are color-coded by species (setosa, versicolor, virginica) using a legend. Built with D3 v6, it loads CSV data from GitHub, uses local ES6 modules for a reusable `scatterPlot` function, and leverages `scaleLinear`, `axisLeft`, and `axisBottom` for axes, with a `setInterval` driving the axis updates.
