This animated scatter plot cycles through different Iris flower measurements, switching the x-axis dimension every few seconds while keeping sepal length on the y-axis. Data points are color-coded by species (setosa, versicolor, virginica) with a legend and title displayed on screen. Built with D3 v6, it uses `scaleLinear`, `axisBottom`, `axisLeft`, and `setInterval` to update the visualization, reading the CSV dataset from a GitHub gist and rendering as SVG.
