This interactive scatterplot animates through different pairings of measurements from the classic Iris dataset, cycling the x-axis among petal width, sepal width, petal length, and sepal length while keeping sepal length on the y-axis. Each of the three iris species is represented by a distinct color and is accompanied by a static legend. The visualization is built with React and D3, using `d3.csv` for data loading, `scaleLinear` and `axisBottom`/`axisLeft` for scales and axes, and a `setInterval` callback to update the chart. SVG circles render the points, with a custom `scatterPlot` module managing the reusable chart configuration.
