This animated scatter plot explores the Iris flower dataset by cyclically rotating which of four measurements (petal width, sepal width, petal length, sepal length) is mapped to the x-axis every two seconds, while the y-axis remains fixed. The visualization distinguishes the three iris species using hardcoded colors (blue, lawngreen, orange) via a switch statement. It uses D3.js APIs including `csv`, `scaleLinear`, `axisLeft`, `axisBottom`, `extent`, and `join`, with a reusable `scatterPlot` module. Data is loaded from a GitHub Gist CSV, rendered as SVG circles with a custom font.
