This animated scatter plot of the Iris dataset cycles through four different feature combinations on the x-axis—petal width, sepal width, petal length, and sepal length—while the y-axis remains fixed on sepal length. Points are colored by species (setosa, versicolor, virginica) and switch between elliptical and circular shapes. Built with D3.js (`d3.csv`, `d3.scaleLinear`, `d3.axis`), it updates the plot every few seconds using `setInterval`, re-rendering axes and labels dynamically in SVG. The visualization appears to load data from a GitHub-hosted CSV and includes a custom legend with species names and colors.
