This interactive scatter plot visualizes the Iris dataset, displaying petal and sepal measurements with points colored by species (setosa, versicolor, virginica). Using D3.js v6 with SVG rendering, the visualization cycles through four variable combinations on the x-axis at regular intervals via `setInterval`, while the y-axis remains fixed. The chart includes a species legend, axis labels, and a title, with the reusable `scatterPlot` module handling scales and axes through D3's `scaleLinear`, `axisLeft`, and `axisBottom`. Data is loaded asynchronously from a GitHub-hosted CSV file.
