This animated scatter plot explores the Iris dataset, cycling through different measurements on the x-axis to reveal relationships between sepal and petal dimensions. Data points are color-coded by species using orange, blue, and black markers, with a custom legend and rotating axis labels. Built with D3 v6, the visualization uses the reusable `scatterPlot` module with `scaleLinear`, `axisLeft`, and `axisBottom` to render SVG circles and axes. A `setInterval` timer switches the x-axis variable every few seconds, smoothly updating the chart to compare all four measurement combinations.
